This week in class we will wrap up evolution and start classification. Plus our tadpoles are quickly turning into very cute little frogs.
I found the perfect topic for this weeks blog. According to National Geographic, scientists in western India have recently discovered fourteen new species of "Dancing Frogs."
Explain in your response, how article and video relates to evolution. Then try and hypothesize how it relates to classification. What is up with the dance? Why do they do it? Are these dancing frogs in trouble?
The idea of Dancing Frogs sounds as if it rather belongs in a children’s book than anything, but along the Western Ghats of India, such an idea has come true. Fourteen new species of dancing frogs, adding to the ten already discovered, has not only opened up a huge amount of study, but also presented an urgent message that scientists must know. Although it would be entertaining, the aforementioned frogs cannot do the tango; however, they can move their legs in a special way. The male frogs stretch their legs to get the attention of other female frogs as a mating “call”, due to the constant loud drone of streams and waterfalls that mute the sounds of an actual call. This is not only an interesting concept, but one that is derived from evolution. Millions of years ago, these dancing frogs did not probably dance as their instinct, but rather, they may have descended from a group of frogs in a less noisy habitat. When a group of frogs emigrated from their original habitat into the loud, river-ridden ghats, natural selection occurred: the frogs that learned how to gain the attention of their mates to continue their bloodline were the ones that had children and passed such traits on. Although evolution is a concept that we think of not happening anymore, it may just happen with these dancing frogs once again. These entertaining amphibians are dancing with extinction, all because of farming and other human activity in their usual habitat. Scientists are desperately working to save such intriguing species, and perhaps they will evolve once again to find a new habitat that will suit their dancing lifestyle.
After reading this article, I found it interesting how in this newly found species, the male front "dances" by lifting his leg up and almost stretching to attract the female. But, it also appears that because of its habitat, the newly found species are going extinct. This video relates somewhat to evolution because these frogs were probably frogs that lived mostly in water, so they didn't need to go extinct because they were the fittest for their environment. But now that their environment is losing water, they aren't fit for their environment, and according to the theories of evolution, only the fittest for the environment will survive, and that could possibly be why they're going extinct, I think. The dance that they do, is odd. Scientists say they haven't seen frogs do this in the past, but maybe a long long time ago, these frogs did that with their legs to help them, not just finding there mate. But, now as time went on, the legs could just now be used to attract their mates, because the other thing they used their legs for would be gone. Yet, I still think these dancing frogs are in trouble, because their environment that they're most fittest to survive in is changing, and then they won't survive. Maybe, come dramatic thing will happen, and with this discovery, it could possibly lead to more.
These new frog species are a remarkable example of evolution. Found exclusively in the Western Ghats, these frogs practice the courtship ritual of leg waving or foot-flagging, which has been noted in a number of species across the world on several continents. Also, the Indian scientists have revealed that the frogs belong to the genus Micrixalus, an ancient group of animals that can be dated back to the time of the dinosaurs, so perhaps all of these foot-waving species can be dated back to a common ancestor (Pangea broke up after the appearance of frogs in the Triassic period). It’s a good example of Charles Darwin’s theory of descent with modification. These frogs also fit Darwin’s other theory of natural selection. Since these frogs are both tiny and live in fast-moving streams, it would be difficult for males to produce a loud enough mating call to attract a mate; thus, they make a visual display instead. The frogs that evolved these visual behaviors were more likely to produce offspring, so the vocally-calling frogs eventually died out.
Dancing Frogs sounds very interesting to watch. However, the ability to watch this event may disappear as these "dancing frogs" are becoming extinct. The reason they make the movement with their legs (That looks as though it's dancing) is because they are making an attractive gesture to females in the area because mating is becoming intensely competitive. The reasoning for this is because the habitat in which they live is becoming abnormally dry. Also, these frogs are so small that the streams are strong enough to possibly take a frog or two down river. The frogs mating relate to Darwin's theory of Natural Selection. They see that in order to survive they must mate and through little behaviors the females pick the best males. If frogs make that dance move more commonly, then females will choose those who make the moves. These frogs are very much so in trouble and it may be too late to save them as they are recently discovered and are already on the edge of extinction.
On May 9th, in western India, 14 new species of Dancing Frogs were discovered. At first, you may think, "Dancing Frogs? Just how talented are these creatures?" Strangely, their title does come into play with their mating rituals. Male dancing frogs will stretch their hind leg and extend their webbed foot to attract mates-- also known as foot-flagging. Unfortunately, despite this new discovery, it may end up being short-lived for scientists. The habitats for these creatures has gradually depleted over the past 12 years, and if this pattern continues, the Dancing Frogs may really live their final dance. Based on the information from both the article and the video, this can connect to evolution through the frogs' environment. Since they are surrounded by water, there is already enough noise as is. Compared to many decades ago, there may have not as been as much noise, so these frogs could have used their mating calls in order to attract mates. However, due to migrating into a new habitat for whatever reason, these frogs could no longer use their calls due to the overpowering sound of both the water and its currents. In addition, natural selection also plays a heavier role today due to their current habitat drying up, so finding mates has also become more competitive. Considering all of the types of Dancing Frogs, there would be no surprise if some sort of isolation mechanism was involved to help make each species' differences. Through these differences and similarities, classification can also be applied through factors such as their environment, similar patterns and characteristics, and behaviors. Personally, I feel that these frogs will be in danger if their habitat continues to dry up, yet if they have managed to adapt from their previous environment, there is always a chance that they can make that reoccur.
Although I do not think that the dancing frogs have to do with evolution per say, I enjoyed this article a lot. What may be called "evolution" is actually just an adaption, learned behavior to help them survive. Anyway, this article was very interesting to read as it exemplifies the diversity of Earth and how new species are found every day. After experiencing behavioral isolation due to the loud rushing water and their mating calls being drowned out, the frogs obviously worked smarter, not harder, and discovered a new way of communicating with each other. They are a testament to the genius of nature. These frogs should be protected by the Indian government in order to preserve their uniqueness and so they are able to be studied by scientists. If they are endangered then efforts should be made to help them out. On the subject of classification, now that scientists will have to classify them there will be a little less room in the classification system. Although they will obviously be put in Amphibia, there will have to be names thought of for 14 more species in the world. I'm sure there are plenty of scientists who will be willing to help, however.
These quirky little frogs definitely relate to evolution and classification. Interestingly, the "dancing" is an evolutionary response to changes in the environment; the monsoon during mating season creates waterfalls, making it hard for females to hear the traditional mating call of frog males. Thus, the dancing is another way of attracting attention from females and warning off other males. The classification aspect comes into play in that these new species will have be sorted into the established classification system. The article suggests that these dancing frogs may be related to similar frogs in the Amazon or in Australia, but I think it would be fascinating to find out if these frogs obtained dancing as a behavior from a common ancestor and then were geographically separated, or if the common ancestor did not have this defined character and each species developed/evolved to dance separately. The answer would prove to be invaluable in figuring out where they fit in. In addition, I do think the ecological threats these frogs face are very real and pose a serious threat to the survival of the species`. India is becoming a more industrialized country, and with industrialization comes the destruction of many places in nature. Hopefully, scientists will be able to educate people on the dangers of upheaval in an environment so the damage can be minimized.
These "dancing frogs" are definitely a rare find. It is so interesting that scientists have found 14 new species, as this nearly doubles the previous amount of known species. The evolution of their mating behavior is also very cool. They most likely developed this interesting leg-wave type of dance because their mating calls were drowned out by the noise of the streams and waterfalls they live near. This is natural selection at its finest. The frogs with the ability to attract a mate without using a mating call (the most favorable variation) were able to reproduce. Eventually, that trait would have spread to many other generations, and the frogs that didn't do this "dance" would die out. It is a unique way of adapting to an environment. Despite their fascinating behavior, these frogs are definitely in danger. The article said that human interference (things like deforestation and commercializing) are reducing the amount of these frogs. Scientists say areas that were once abundant in dancing frogs now may have very few. This is a dangerous prospect that is true for many species, not just the frogs. Habitats of rare and interesting species like these need to be protected.
I do think evolution played a part in this frog existence. They adapted to not being able to hear each other calling the mates to waving their hind legs in the air to attract mates or even push other males away. These frog are in danger of extinction. In the video the scientist said that some of the frogs are becoming extinct before scientist are able to discover and document them. The frog has been around since dinosaur age and it amazes me that we are just now discovering these frogs but we may have discovered them too late to really know what the frog is about or how it came to be, unless we can save the jumping frogs.
These frogs evolved to dance to attract mates. The males stretch their hind legs out to attract mates. They adapted to this, because they were not able to hear each other when they called their mates, so they just waved them down. I do think these frogs are close to extinction, because of their size. The video stated that the frogs are easily swept away from the stream. The females also had issues keeping their eggs from floating away, so they started covering them with sand and rocks to hold them still.
This relates to evolution because the frogs have been dancing since the dinosaur era. This relates because it shows that the frogs have traits from their descendants. They have evolved from making noise frogs to stretching their legs frogs to attract females. The frogs are in danger because the rivers are catching them in a wave and taking them downstream. The frogs relate to classification because they will be difficult to decide on, with their new discovery of the legs.
The Dancing frog is a prime example of evolution. Unlike their genetically similar counterparts these frogs have very long hind legs that allow them to stretch and attract mates. This is an obvious sign of evolution because these frogs developed alternate uses for their legs over a longer period of time that most other frogs do not do. Perhaps, some time in the ancient ancestry of the dancing frogs, they began to "dance" in order to attract more mates than other frogs.These frogs at facing a potential extinction due to the changing rainfall patterns. Scientists discovered are attempting to collect as many subjects as possible to prevent their extinction. It still amazes me that we are discovering so many new species every day. I can only wonder what wonders the undiscovered world still holds to be found.
These "dancing frogs" are quite interesting. I believe this trait was acquired as mating became harder and possibly part of the reason for all these new species of frogs. I don't think its evolving but adapting to its environment and surviving and mating out side of their circle as a way to keep their species alive.
They probibly use to comunicate too and no obviuly they eloved to overcomne this problem so i think they are fine and i love the one frog that looked like he was trying to put his arm around the other oen on the rocks.
The dancing frog developed from another frog that had shorter legs. These frogs developed longer legs because longer legs are more attractive to other frogs. The only thing that I think evolution should of taken care of is the stream can carry away the frogs and kill them. The only way their species can survive is if they evolve with stronger legs.
The frogs are evolving because they are adapting to their environment. They figured out a new way to catch the attention of the females. next this relates to classification because it said they are all in the same family which is a classification level. The dance is just another way to catch the females attention. their mating calls don't work so they do this. i think these frogs are perfectly fine because they figured out a way to do it in their noisy environment.
The fact the females had to change their way of getting the males attention and trying to find a mate is an example of evolution. This also relates to classification because of this new feature their classification now has to be new and different. The "dance" that is done also shows that no matter what cost of the environment organisms will do anything they can to reproduce and keep the species alive. This new study may also lead to more new species and studies because of how they adapted and survived that maybe other species that we have already discovered have done the same thing and have adapted into a new species once again through the process of evolution. This also maybe a precursor to all the apocalypse theories on if there is one do we survive. As I said before it shows that organisms always find away to live, and in the event of our world crumbling right before our eyes we will find away to survive.
The dancing frogs were discovered along the streams of India. The male frogs "dance" or swing their legs to impress a female. They are also on the endangered species list because their habitat is becoming dryer and they are so small that they have trouble not getting swept down the rivers.
This article has to do with evolution because when the frogs needed to find a way to attract a mate they evolved longer legs which they could move around to attract a mate after they experienced behavior isolation and could no longer mate normally. The Indian government should do everything in its power to protect these "dancing" frogs and learn more about them and why they dance. The scientist will have to classify all these new species of frogs before it's too late. They will need to name all these frogs and figure out where they go in the system.
After reading the article and watching the video I think that this video relates to evolution because the frogs acquired the "dancing" do to the fact that females couldn't hear them croak during mating season. The males acquired the dancing because of the waterfalls so they evolved to better fit their environments. This connects to classification because since these new species of frogs were found they will need to be classified as a new species and receive a latin name. The frogs dance because that is how they attract mates, also they dance and use "kickboxing" to keep other males off of their territory. I think that the frogs are in trouble because their environment is in trouble and I don't believe that they will evolve quick enough to survive since the evolution process takes a long time.
These "dancing" frogs, as they call them, aren't really dancing at all. It's what we refer to as a mating ritual, and I would guess the females choose the frogs with the longer legs, maybe because of hopping ability, or swimming ability. Maybe their legs help them hold on to the rocks so they don't get carried by the stream, and natural selection favors the frogs with longer legs. Either way, we need to classify these frogs, and fast, or there will be no more to classify.
After finishing the article and watching the short video, I find pretty cool how they lift their legs to attract mates. Like the Dr. in the video said, it is a very unique way of behaving. I personally think that it is almost like a survival tactic. These frogs have evolved over their time in this wet, slippery environment to be able to attract their mates in a different manner than would be most efficient ordinarily. This is how it relates to evolution, if these frogs didn't do their "dance", then they would not be able to find a mate, causing an almost guaranteed extinction. I think they do this dance because they live in a harsh, rapid environment, in which they could/can easily get swept away by the rushing waters. This also relates to classification because they now have a very unique, and distinct characteristic that no other species of frog may have, therefore, they may have to be grouped in a different category. These frogs are indeed in danger, after all, they are "going extinct", they have started to adapt to means of survival in which they may not be comfortable with, but yes, they are in danger.
The "Dancing Frogs" of India can be related to evolution because they probably did not originally use this unique mating tactic. As we know, most animals have an audible mating call, while these frogs do not. I believe that over time, while living in a loud, noisy rain-forest environment, these frogs resorted to a different tactic that we now know as "foot flagging." Clearly it worked, since all male frogs of this species have the same instinct. This also relates to classification because these frogs are in the class Amphibia. Overall, I think it is cool that these frogs have such a unique mating tactic.
Dancing frogs can show us a lot of their history in a short amount of time. While reading the article one is able to quickly establish that because of enviormental changes making the dancing frogs home dry they now have to compete over mating. This is a sign of their soon to come extinction. As their enviorments changed so did their mating rituals and leg sizes, a sign of evolution. Even if they continue to evolve they won't be able to make it through. They are too close to extinction to survive at this point.
These so called "dancing frogs" directly relate to evolution because since they are the size of a walnut, the males have developed an eye catching mating habit to attract females. Dancing frogs could be connected to classification by being put into an already existing group of Linnaeus. Also it said that they are endangered. This is a HUGE issue considering we just discovered them!! We can only hope for the best and attemp as hard as we can to keep their species alive.
The dancing frogs are quite interesting. And scientists found these just in time as most of these species are extinct. This relates to evolution because this shows an evolutionary change in two different types of frogs. Pick any type of frog you want and compare it to the dancing ones and any one of them won't dance for a mate. This also relates to classification because these frogs probably have a different genus and species than any other type of frog.
The dancing frogs are very interesting. The kicking of the legs is to attract mates. I also noticed that they puff out their throats which is probably also another way to attract mates. This dancing happened from a mutation and has stuck with the frog. Because of this mutations productivity it has stuck with the frog, this is one of Darwin’s natural selection theories. The only bad part of the dancing frogs is that they are so small they get washed away in the streams in their environment. Once discovering a new species scientists have to classify it. This process can be long or short, in this case short because it is the same as any other frog but just with different features.
It's late at night, so I am going to keep this brief. This relates to evolution because the frogs probably developed their "dancing" to better fit their environment "the waterfalls" so they could survive. However, their environment is changing yet again, as it is drying up. They may not survive the changes, so scientists are right in collecting samples. I don't understand why they take frogs away when they are endangered though. Time will tell if evolution will move fast enough for these frogs, I'm going to say they'll all die though. As it relates to classification where do these go? I assume with the other frogs but that's too simple for a scientist solution. They'll probably change something that kids will have to learn in the future.
At first glance at this weeks blog, the title immediately intrigued me. "Dancing Frogs"? That seemed like something I would like. The article explains how the male frogs stretch their legs to attract the attention of the female frogs. They do this because of the inability to use a normal mating noise due to the loud volume of the stream. This relates to evolution because this species of frogs eventually changed to survive in its environment. This displays natural selection because the frogs who did not adapt did not survive. This article also relates to classification because the frogs will now need to be classified differently. Because of their new adaptation, they will be different from their ancestors. In order for this species of frogs to exist, they will need to evolve into a bigger size. This will not cause them to be swiped away buy the roaring stream. The fact that these frogs dance to attract the ladies is amazing. If boys danced to attract girls I would be won over!
Dancing Frogs are a truly amazing discovery. After reading the article and watching the video, I believe that the "dance" that the males do to attract the females relates to evolution. Due to the environment, they had to adapt in order to mate with the females. This relates to classification because now that there are more species being discovered, scientists are going to have to figure out how these frogs will fit in taxonomy system. Since they are exhibiting different traits form many frogs, scientists will have to study these frogs closely. Unfortunately, these frogs are in danger. Their environment is changing, and that can cause dramatic changes in their population growth and survival rate.
This relates to evolution because since most frogs don't 'dance' that means that they evolved in or order to find a mate. would dancing be a derived trait for the cladograms we're learning about? Its amazing how we're still discovering new species and its sad to hear that they are already endangered. Hopefully we can find a way to help them so that they dont go extinct before they're even discovered.
Because of where the frogs live, they had to change the way they mated. So they evolved from making a sound to attract mates to "dancing". These frogs are in trouble because they are already becoming extinct and it maybe too late to save these frogs.
The male frogs are the ones that dance, they do this because they need to attract female frogs, this is there "mating call." I think this has to do with evolution because they just found these fourteen new dancing species and they needed to find a way to attract mates. These frogs are endangered and they are trying to have the frogs reproduce and keep the ones that are alive safe. These frogs can be easily swept away and I think that is a main reason they are becoming endangered, they are so small.
This video relates to evolution because the dancing frogs are attracting mates because of natural selection. Impressing a female gets them to mate with you and so they can produce offspring. I just find it funny that the frogs dance to attract females. But it also shows how they evolved because I dont believe frogs started dancing at birth.
This video relates to evolution because usually male frogs have to call their mates using a noise. The issue is these frogs live under waterfalls so the females cannot here the males mating call. Therefore over time frogs have started to do this weird dance move to attract the females. Over time they adjusted to trait that best suits the to survive. They evolved over time to find a way to attract the females.
Obviously, this behavior in frogs is not widespread, and is a defining characteristic of this particular species. This relates to evolution because this was once a different frog, but it adapted and changed to better survive. To classify them, they would be farther along in the lineage of frogs. Their mating behavior is much different than that of the typical frog. The dance is unique to them to attract the attention of the females. I know I would pay attention if a boy started dancing unexpectedly! Unfortunately, these frogs are very much in trouble, as they are dying out. It is essential for the Western Ghats to take precautions in order for their survival. As the dominating species, it is important for us to do the best we can to save them. These creatures are fascinating and should stick around!
It is truly amazing that this species of frogs have in fact adapted to their environment in such a unique way. Since their mating call is unheard due to the rushing water from monsoons, they stretch their legs which attracts females. This trait is done by many other species of frogs that are not related to the genus Macrixaus from different areas around the globe, including Australia and South America. This can be associated with the fact that evolution can happen to many other species in the same environment, called Coevolution. Sadly, these frogs are in danger because of the expansion of farming.Although necessary, these creatures may eventually disappear if they are not protected by the government. If this does not happen, these frogs will have to find another way to adapt to their ever changing environment.
I think this is pretty funny way of evolving, its so unique. This dance is actually a way to attract mates, because if a boy can dance hes a keeper. These frogs are not the first species to dance their way into their mate's life, other species near the frogs do similar dances. Coevolution is what this is referred to. Sadly the frogs are in danger from farming, hopefully the dance lives on as do the frogs
This video relates to evolution because the frogs adapted their "dances" because of evolution. Since they don't have very many traits that make them well suited for their environment, they are endangered. They are being swept away the rivers currents and the population might soon become extinct. They adapted this mating call because the population is shrinking, so it is becoming harder and harder for them to find a mate, and to get the females attention, they simply dance. This relates to classification because since scientists found these dancing frogs, they are realizing that there are more frog species that they don't know about, so they are trying to classify all of them before they go extinct.
This discovery of these new species of frogs is remarkably relate able to our unit on classification and evolution. I can see the similarities of these 14 frog species to the many finch species Darwin found on the Galapagos Islands in the way they seemed to have evolved. Since they both have several species within the "frog" category, I can hypothesize they both can from divergent evolution: specifically adaptive radiation. Supposedly, the frogs adapted to their environment by dancing, so who's to say they haven't migrated to another location where they can better thrive? I am intrigued, wondering what the number of species of the frogs and finches can tell us about their form of evolution or their evolution patterns. I'm positive this is happening everywhere, we just don't even see it. Some other similarities in the environments of the two creatures makes me wonder if the fact that the two lands were not populated(for the most part) contributes to the form of evolution that occurs, or how quickly it occurs. Hopefully what I think is true: the "survival of the fittest" will decline the amount of species of frogs across the Western Ghats, but the fittest species will continue to live on in that particular environment. Another possibility could be that some or all of the frog population have began to migrate to be able to adapt where they have a better chance at surviving. Overall, this is a very interesting find, and I am curious to see what is in the future for these special frogs.
This really fascinated me, this behavior in frogs in not 'normal', for most frogs don't do this. Usually male frogs make a noise to call for a mate. Now, due to the noise of the waterfall, these frogs cannot be heard, perhaps. After all their unsuccessful attempts to find a mate, they started 'dancing' in order to find a mate. When this started becoming successful, the frogs started to do this instead of noises, as it was now best suited for their survival.
This article and video relates to evolution because the frogs have made an adaptation based on their environment. They changed their ways to suite the environment around them. Since not all frogs do this, I'm assuming that they learned to do this, and their oldest ancestors did not do this. Because, if their oldest ancestors did this, a lot more species of frogs would be doing this "dancing".The dance they do is a sort of mating call. It attracts females so they can mate with them. These frogs are in danger, and we need to save them. We might be able to learn much more from these species. We should study them and learn what other adaptations they made, if any, and apply that to evolution.
Upon watching the video, it became aparent that this particular characteristic of "dancing' must be the result of natural selection. At some point, a frog must have undergone a mutation which created the urge for spasms or the stretching of specific limbs during the mating season (or all seasons for that matter). This trait would have been extremely helpful because mating calls were not very effective. Since this allowed for better mating, the trait became preferable and was passed on from generation to generation. On the other hand, this could also be the result of behavioral isolation. The calling did not work, so they resorted to dancing so that they might still efectively reproduce.
Its an odd way to attract the ladies, the way the frogs stick out their legs. I wonder what it would be like if guys did that to girls, it would be very strange. Anyway, i hope the scientists can document all these frogs. It would be a shame if we miss a new species of frog because we ran out of funding or time. I hope we can find many more new frogs, and see if there are any differences between them and thew ones we already found. The more differences they have, he farther they will go in the classification scale. Who knows, scientists could be on the verge of a evolutionary breakthrough! (though I doubt it). I wonder, are the frogs the only animals that "dance"? I would like to see other animals like a giraffe dance the way these frogs do. A little weird, but I think it would be entertaining. I think these frogs are in danger of being eradicated, and I hope we can do whatever we can to save these little fellas
This video relates to evolution because the frogs have adapted a new way to attract mates, that will actually work in their environment. I think they do their dance because it is easier for a female to see them. In the environment, the frogs may not be able to hear the singing-mating call. It relates to classification because probably somewhere in the past groups that the frog is related to did this leg mating call. They are in trouble because of the river, causing them to fall in and die.
What an amazing evolutionary adaptation! That is a perfect example of sexual selection. The females chose their mates based on an appearance or behavior. I would have loved to see one of those frogs doing their little dance. It's very sad that some of those species are going extinct before we can document them. I believe it would be a great idea to teach our frogs to dance so they could carry on the tradition. I also how recently the mutation occurred that made the frog want to "dance". I suppose if a mating call was not heard that the frog could do that to attract the mate without any sound.
It's truly amazing how the frogs were able to find a way to attract a mate next to a noisy waterfall like that. The fact that these frogs realized that they couldn't hear each other and found another way to get each others attention that they all understood is amazing. Using a dance to replace a mating call is a smart move on the frogs part. I don't think these frogs are in danger. As long as they can see each other, they will be able to mate.
I think this article is a prime example of evolution. Since they can't hear each other over all the noise they decided to start dancing!. As interesting as this may be it can also have its downfalls such as the female frogs can't see the male so she just kinda moves on. They need to come up with a way that can be heard over the sound. Because vision isn't always as good as hearing
The idea of Dancing Frogs sounds as if it rather belongs in a children’s book than anything, but along the Western Ghats of India, such an idea has come true. Fourteen new species of dancing frogs, adding to the ten already discovered, has not only opened up a huge amount of study, but also presented an urgent message that scientists must know. Although it would be entertaining, the aforementioned frogs cannot do the tango; however, they can move their legs in a special way. The male frogs stretch their legs to get the attention of other female frogs as a mating “call”, due to the constant loud drone of streams and waterfalls that mute the sounds of an actual call. This is not only an interesting concept, but one that is derived from evolution. Millions of years ago, these dancing frogs did not probably dance as their instinct, but rather, they may have descended from a group of frogs in a less noisy habitat. When a group of frogs emigrated from their original habitat into the loud, river-ridden ghats, natural selection occurred: the frogs that learned how to gain the attention of their mates to continue their bloodline were the ones that had children and passed such traits on. Although evolution is a concept that we think of not happening anymore, it may just happen with these dancing frogs once again. These entertaining amphibians are dancing with extinction, all because of farming and other human activity in their usual habitat. Scientists are desperately working to save such intriguing species, and perhaps they will evolve once again to find a new habitat that will suit their dancing lifestyle.
ReplyDeleteAfter reading this article, I found it interesting how in this newly found species, the male front "dances" by lifting his leg up and almost stretching to attract the female. But, it also appears that because of its habitat, the newly found species are going extinct. This video relates somewhat to evolution because these frogs were probably frogs that lived mostly in water, so they didn't need to go extinct because they were the fittest for their environment. But now that their environment is losing water, they aren't fit for their environment, and according to the theories of evolution, only the fittest for the environment will survive, and that could possibly be why they're going extinct, I think. The dance that they do, is odd. Scientists say they haven't seen frogs do this in the past, but maybe a long long time ago, these frogs did that with their legs to help them, not just finding there mate. But, now as time went on, the legs could just now be used to attract their mates, because the other thing they used their legs for would be gone. Yet, I still think these dancing frogs are in trouble, because their environment that they're most fittest to survive in is changing, and then they won't survive. Maybe, come dramatic thing will happen, and with this discovery, it could possibly lead to more.
ReplyDeleteThese new frog species are a remarkable example of evolution. Found exclusively in the Western Ghats, these frogs practice the courtship ritual of leg waving or foot-flagging, which has been noted in a number of species across the world on several continents. Also, the Indian scientists have revealed that the frogs belong to the genus Micrixalus, an ancient group of animals that can be dated back to the time of the dinosaurs, so perhaps all of these foot-waving species can be dated back to a common ancestor (Pangea broke up after the appearance of frogs in the Triassic period). It’s a good example of Charles Darwin’s theory of descent with modification. These frogs also fit Darwin’s other theory of natural selection. Since these frogs are both tiny and live in fast-moving streams, it would be difficult for males to produce a loud enough mating call to attract a mate; thus, they make a visual display instead. The frogs that evolved these visual behaviors were more likely to produce offspring, so the vocally-calling frogs eventually died out.
ReplyDeleteDancing Frogs sounds very interesting to watch. However, the ability to watch this event may disappear as these "dancing frogs" are becoming extinct. The reason they make the movement with their legs (That looks as though it's dancing) is because they are making an attractive gesture to females in the area because mating is becoming intensely competitive. The reasoning for this is because the habitat in which they live is becoming abnormally dry. Also, these frogs are so small that the streams are strong enough to possibly take a frog or two down river. The frogs mating relate to Darwin's theory of Natural Selection. They see that in order to survive they must mate and through little behaviors the females pick the best males. If frogs make that dance move more commonly, then females will choose those who make the moves. These frogs are very much so in trouble and it may be too late to save them as they are recently discovered and are already on the edge of extinction.
ReplyDeleteOn May 9th, in western India, 14 new species of Dancing Frogs were discovered. At first, you may think, "Dancing Frogs? Just how talented are these creatures?" Strangely, their title does come into play with their mating rituals. Male dancing frogs will stretch their hind leg and extend their webbed foot to attract mates-- also known as foot-flagging. Unfortunately, despite this new discovery, it may end up being short-lived for scientists. The habitats for these creatures has gradually depleted over the past 12 years, and if this pattern continues, the Dancing Frogs may really live their final dance. Based on the information from both the article and the video, this can connect to evolution through the frogs' environment. Since they are surrounded by water, there is already enough noise as is. Compared to many decades ago, there may have not as been as much noise, so these frogs could have used their mating calls in order to attract mates. However, due to migrating into a new habitat for whatever reason, these frogs could no longer use their calls due to the overpowering sound of both the water and its currents. In addition, natural selection also plays a heavier role today due to their current habitat drying up, so finding mates has also become more competitive. Considering all of the types of Dancing Frogs, there would be no surprise if some sort of isolation mechanism was involved to help make each species' differences. Through these differences and similarities, classification can also be applied through factors such as their environment, similar patterns and characteristics, and behaviors. Personally, I feel that these frogs will be in danger if their habitat continues to dry up, yet if they have managed to adapt from their previous environment, there is always a chance that they can make that reoccur.
ReplyDeleteAlthough I do not think that the dancing frogs have to do with evolution per say, I enjoyed this article a lot. What may be called "evolution" is actually just an adaption, learned behavior to help them survive. Anyway, this article was very interesting to read as it exemplifies the diversity of Earth and how new species are found every day. After experiencing behavioral isolation due to the loud rushing water and their mating calls being drowned out, the frogs obviously worked smarter, not harder, and discovered a new way of communicating with each other. They are a testament to the genius of nature. These frogs should be protected by the Indian government in order to preserve their uniqueness and so they are able to be studied by scientists. If they are endangered then efforts should be made to help them out. On the subject of classification, now that scientists will have to classify them there will be a little less room in the classification system. Although they will obviously be put in Amphibia, there will have to be names thought of for 14 more species in the world. I'm sure there are plenty of scientists who will be willing to help, however.
ReplyDeleteThese quirky little frogs definitely relate to evolution and classification. Interestingly, the "dancing" is an evolutionary response to changes in the environment; the monsoon during mating season creates waterfalls, making it hard for females to hear the traditional mating call of frog males. Thus, the dancing is another way of attracting attention from females and warning off other males. The classification aspect comes into play in that these new species will have be sorted into the established classification system. The article suggests that these dancing frogs may be related to similar frogs in the Amazon or in Australia, but I think it would be fascinating to find out if these frogs obtained dancing as a behavior from a common ancestor and then were geographically separated, or if the common ancestor did not have this defined character and each species developed/evolved to dance separately. The answer would prove to be invaluable in figuring out where they fit in. In addition, I do think the ecological threats these frogs face are very real and pose a serious threat to the survival of the species`. India is becoming a more industrialized country, and with industrialization comes the destruction of many places in nature. Hopefully, scientists will be able to educate people on the dangers of upheaval in an environment so the damage can be minimized.
ReplyDeleteThese "dancing frogs" are definitely a rare find. It is so interesting that scientists have found 14 new species, as this nearly doubles the previous amount of known species. The evolution of their mating behavior is also very cool. They most likely developed this interesting leg-wave type of dance because their mating calls were drowned out by the noise of the streams and waterfalls they live near. This is natural selection at its finest. The frogs with the ability to attract a mate without using a mating call (the most favorable variation) were able to reproduce. Eventually, that trait would have spread to many other generations, and the frogs that didn't do this "dance" would die out. It is a unique way of adapting to an environment. Despite their fascinating behavior, these frogs are definitely in danger. The article said that human interference (things like deforestation and commercializing) are reducing the amount of these frogs. Scientists say areas that were once abundant in dancing frogs now may have very few. This is a dangerous prospect that is true for many species, not just the frogs. Habitats of rare and interesting species like these need to be protected.
ReplyDeleteI do think evolution played a part in this frog existence. They adapted to not being able to hear each other calling the mates to waving their hind legs in the air to attract mates or even push other males away. These frog are in danger of extinction. In the video the scientist said that some of the frogs are becoming extinct before scientist are able to discover and document them. The frog has been around since dinosaur age and it amazes me that we are just now discovering these frogs but we may have discovered them too late to really know what the frog is about or how it came to be, unless we can save the jumping frogs.
ReplyDeleteThese frogs evolved to dance to attract mates. The males stretch their hind legs out to attract mates. They adapted to this, because they were not able to hear each other when they called their mates, so they just waved them down. I do think these frogs are close to extinction, because of their size. The video stated that the frogs are easily swept away from the stream. The females also had issues keeping their eggs from floating away, so they started covering them with sand and rocks to hold them still.
ReplyDeleteThis relates to evolution because the frogs have been dancing since the dinosaur era. This relates because it shows that the frogs have traits from their descendants. They have evolved from making noise frogs to stretching their legs frogs to attract females. The frogs are in danger because the rivers are catching them in a wave and taking them downstream. The frogs relate to classification because they will be difficult to decide on, with their new discovery of the legs.
ReplyDeleteThe Dancing frog is a prime example of evolution. Unlike their genetically similar counterparts these frogs have very long hind legs that allow them to stretch and attract mates. This is an obvious sign of evolution because these frogs developed alternate uses for their legs over a longer period of time that most other frogs do not do. Perhaps, some time in the ancient ancestry of the dancing frogs, they began to "dance" in order to attract more mates than other frogs.These frogs at facing a potential extinction due to the changing rainfall patterns. Scientists discovered are attempting to collect as many subjects as possible to prevent their extinction. It still amazes me that we are discovering so many new species every day. I can only wonder what wonders the undiscovered world still holds to be found.
ReplyDeletewww.independent.co.uk/news/14-new-dancing-frog-species-discovered--just-as-they-are-about-to-become-extinct-9337
These "dancing frogs" are quite interesting. I believe this trait was acquired as mating became harder and possibly part of the reason for all these new species of frogs. I don't think its evolving but adapting to its environment and surviving and mating out side of their circle as a way to keep their species alive.
ReplyDeleteThey probibly use to comunicate too and no obviuly they eloved to overcomne this problem so i think they are fine and i love the one frog that looked like he was trying to put his arm around the other oen on the rocks.
ReplyDeleteThe dancing frog developed from another frog that had shorter legs. These frogs developed longer legs because longer legs are more attractive to other frogs. The only thing that I think evolution should of taken care of is the stream can carry away the frogs and kill them. The only way their species can survive is if they evolve with stronger legs.
ReplyDeleteThe frogs are evolving because they are adapting to their environment. They figured out a new way to catch the attention of the females. next this relates to classification because it said they are all in the same family which is a classification level. The dance is just another way to catch the females attention. their mating calls don't work so they do this. i think these frogs are perfectly fine because they figured out a way to do it in their noisy environment.
ReplyDeleteThe fact the females had to change their way of getting the males attention and trying to find a mate is an example of evolution. This also relates to classification because of this new feature their classification now has to be new and different. The "dance" that is done also shows that no matter what cost of the environment organisms will do anything they can to reproduce and keep the species alive. This new study may also lead to more new species and studies because of how they adapted and survived that maybe other species that we have already discovered have done the same thing and have adapted into a new species once again through the process of evolution. This also maybe a precursor to all the apocalypse theories on if there is one do we survive. As I said before it shows that organisms always find away to live, and in the event of our world crumbling right before our eyes we will find away to survive.
ReplyDeleteThe dancing frogs were discovered along the streams of India. The male frogs "dance" or swing their legs to impress a female. They are also on the endangered species list because their habitat is becoming dryer and they are so small that they have trouble not getting swept down the rivers.
ReplyDeleteThis article has to do with evolution because when the frogs needed to find a way to attract a mate they evolved longer legs which they could move around to attract a mate after they experienced behavior isolation and could no longer mate normally. The Indian government should do everything in its power to protect these "dancing" frogs and learn more about them and why they dance. The scientist will have to classify all these new species of frogs before it's too late. They will need to name all these frogs and figure out where they go in the system.
ReplyDeleteAfter reading the article and watching the video I think that this video relates to evolution because the frogs acquired the "dancing" do to the fact that females couldn't hear them croak during mating season. The males acquired the dancing because of the waterfalls so they evolved to better fit their environments. This connects to classification because since these new species of frogs were found they will need to be classified as a new species and receive a latin name. The frogs dance because that is how they attract mates, also they dance and use "kickboxing" to keep other males off of their territory. I think that the frogs are in trouble because their environment is in trouble and I don't believe that they will evolve quick enough to survive since the evolution process takes a long time.
ReplyDeleteThese "dancing" frogs, as they call them, aren't really dancing at all. It's what we refer to as a mating ritual, and I would guess the females choose the frogs with the longer legs, maybe because of hopping ability, or swimming ability. Maybe their legs help them hold on to the rocks so they don't get carried by the stream, and natural selection favors the frogs with longer legs. Either way, we need to classify these frogs, and fast, or there will be no more to classify.
ReplyDeleteAfter finishing the article and watching the short video, I find pretty cool how they lift their legs to attract mates. Like the Dr. in the video said, it is a very unique way of behaving. I personally think that it is almost like a survival tactic. These frogs have evolved over their time in this wet, slippery environment to be able to attract their mates in a different manner than would be most efficient ordinarily. This is how it relates to evolution, if these frogs didn't do their "dance", then they would not be able to find a mate, causing an almost guaranteed extinction. I think they do this dance because they live in a harsh, rapid environment, in which they could/can easily get swept away by the rushing waters. This also relates to classification because they now have a very unique, and distinct characteristic that no other species of frog may have, therefore, they may have to be grouped in a different category. These frogs are indeed in danger, after all, they are "going extinct", they have started to adapt to means of survival in which they may not be comfortable with, but yes, they are in danger.
ReplyDeleteThe "Dancing Frogs" of India can be related to evolution because they probably did not originally use this unique mating tactic. As we know, most animals have an audible mating call, while these frogs do not. I believe that over time, while living in a loud, noisy rain-forest environment, these frogs resorted to a different tactic that we now know as "foot flagging." Clearly it worked, since all male frogs of this species have the same instinct. This also relates to classification because these frogs are in the class Amphibia. Overall, I think it is cool that these frogs have such a unique mating tactic.
ReplyDeleteDancing frogs can show us a lot of their history in a short amount of time. While reading the article one is able to quickly establish that because of enviormental changes making the dancing frogs home dry they now have to compete over mating. This is a sign of their soon to come extinction. As their enviorments changed so did their mating rituals and leg sizes, a sign of evolution. Even if they continue to evolve they won't be able to make it through. They are too close to extinction to survive at this point.
ReplyDeleteThese so called "dancing frogs" directly relate to evolution because since they are the size of a walnut, the males have developed an eye catching mating habit to attract females. Dancing frogs could be connected to classification by being put into an already existing group of Linnaeus. Also it said that they are endangered. This is a HUGE issue considering we just discovered them!! We can only hope for the best and attemp as hard as we can to keep their species alive.
ReplyDeleteThe dancing frogs are quite interesting. And scientists found these just in time as most of these species are extinct. This relates to evolution because this shows an evolutionary change in two different types of frogs. Pick any type of frog you want and compare it to the dancing ones and any one of them won't dance for a mate. This also relates to classification because these frogs probably have a different genus and species than any other type of frog.
ReplyDeleteThe dancing frogs are very interesting. The kicking of the legs is to attract mates. I also noticed that they puff out their throats which is probably also another way to attract mates. This dancing happened from a mutation and has stuck with the frog. Because of this mutations productivity it has stuck with the frog, this is one of Darwin’s natural selection theories. The only bad part of the dancing frogs is that they are so small they get washed away in the streams in their environment. Once discovering a new species scientists have to classify it. This process can be long or short, in this case short because it is the same as any other frog but just with different features.
ReplyDeleteIt's late at night, so I am going to keep this brief. This relates to evolution because the frogs probably developed their "dancing" to better fit their environment "the waterfalls" so they could survive. However, their environment is changing yet again, as it is drying up. They may not survive the changes, so scientists are right in collecting samples. I don't understand why they take frogs away when they are endangered though. Time will tell if evolution will move fast enough for these frogs, I'm going to say they'll all die though. As it relates to classification where do these go? I assume with the other frogs but that's too simple for a scientist solution. They'll probably change something that kids will have to learn in the future.
ReplyDeleteAt first glance at this weeks blog, the title immediately intrigued me. "Dancing Frogs"? That seemed like something I would like. The article explains how the male frogs stretch their legs to attract the attention of the female frogs. They do this because of the inability to use a normal mating noise due to the loud volume of the stream. This relates to evolution because this species of frogs eventually changed to survive in its environment. This displays natural selection because the frogs who did not adapt did not survive. This article also relates to classification because the frogs will now need to be classified differently. Because of their new adaptation, they will be different from their ancestors. In order for this species of frogs to exist, they will need to evolve into a bigger size. This will not cause them to be swiped away buy the roaring stream. The fact that these frogs dance to attract the ladies is amazing. If boys danced to attract girls I would be won over!
ReplyDeleteDancing Frogs are a truly amazing discovery. After reading the article and watching the video, I believe that the "dance" that the males do to attract the females relates to evolution. Due to the environment, they had to adapt in order to mate with the females. This relates to classification because now that there are more species being discovered, scientists are going to have to figure out how these frogs will fit in taxonomy system. Since they are exhibiting different traits form many frogs, scientists will have to study these frogs closely. Unfortunately, these frogs are in danger. Their environment is changing, and that can cause dramatic changes in their population growth and survival rate.
ReplyDeleteThis relates to evolution because since most frogs don't 'dance' that means that they evolved in or order to find a mate. would dancing be a derived trait for the cladograms we're learning about? Its amazing how we're still discovering new species and its sad to hear that they are already endangered. Hopefully we can find a way to help them so that they dont go extinct before they're even discovered.
ReplyDeleteBecause of where the frogs live, they had to change the way they mated. So they evolved from making a sound to attract mates to "dancing". These frogs are in trouble because they are already becoming extinct and it maybe too late to save these frogs.
ReplyDeleteThe male frogs are the ones that dance, they do this because they need to attract female frogs, this is there "mating call." I think this has to do with evolution because they just found these fourteen new dancing species and they needed to find a way to attract mates. These frogs are endangered and they are trying to have the frogs reproduce and keep the ones that are alive safe. These frogs can be easily swept away and I think that is a main reason they are becoming endangered, they are so small.
ReplyDeleteThis video relates to evolution because the dancing frogs are attracting mates because of natural selection. Impressing a female gets them to mate with you and so they can produce offspring. I just find it funny that the frogs dance to attract females. But it also shows how they evolved because I dont believe frogs started dancing at birth.
ReplyDeleteThis video relates to evolution because usually male frogs have to call their mates using a noise. The issue is these frogs live under waterfalls so the females cannot here the males mating call. Therefore over time frogs have started to do this weird dance move to attract the females. Over time they adjusted to trait that best suits the to survive. They evolved over time to find a way to attract the females.
ReplyDeleteObviously, this behavior in frogs is not widespread, and is a defining characteristic of this particular species. This relates to evolution because this was once a different frog, but it adapted and changed to better survive. To classify them, they would be farther along in the lineage of frogs. Their mating behavior is much different than that of the typical frog. The dance is unique to them to attract the attention of the females. I know I would pay attention if a boy started dancing unexpectedly! Unfortunately, these frogs are very much in trouble, as they are dying out. It is essential for the Western Ghats to take precautions in order for their survival. As the dominating species, it is important for us to do the best we can to save them. These creatures are fascinating and should stick around!
ReplyDeleteIt is truly amazing that this species of frogs have in fact adapted to their environment in such a unique way. Since their mating call is unheard due to the rushing water from monsoons, they stretch their legs which attracts females. This trait is done by many other species of frogs that are not related to the genus Macrixaus from different areas around the globe, including Australia and South America. This can be associated with the fact that evolution can happen to many other species in the same environment, called Coevolution. Sadly, these frogs are in danger because of the expansion of farming.Although necessary, these creatures may eventually disappear if they are not protected by the government. If this does not happen, these frogs will have to find another way to adapt to their ever changing environment.
ReplyDeleteI think this is pretty funny way of evolving, its so unique. This dance is actually a way to attract mates, because if a boy can dance hes a keeper. These frogs are not the first species to dance their way into their mate's life, other species near the frogs do similar dances. Coevolution is what this is referred to. Sadly the frogs are in danger from farming, hopefully the dance lives on as do the frogs
ReplyDeleteThis video relates to evolution because the frogs adapted their "dances" because of evolution. Since they don't have very many traits that make them well suited for their environment, they are endangered. They are being swept away the rivers currents and the population might soon become extinct. They adapted this mating call because the population is shrinking, so it is becoming harder and harder for them to find a mate, and to get the females attention, they simply dance. This relates to classification because since scientists found these dancing frogs, they are realizing that there are more frog species that they don't know about, so they are trying to classify all of them before they go extinct.
ReplyDeleteThis discovery of these new species of frogs is remarkably relate able to our unit on classification and evolution. I can see the similarities of these 14 frog species to the many finch species Darwin found on the Galapagos Islands in the way they seemed to have evolved. Since they both have several species within the "frog" category, I can hypothesize they both can from divergent evolution: specifically adaptive radiation. Supposedly, the frogs adapted to their environment by dancing, so who's to say they haven't migrated to another location where they can better thrive? I am intrigued, wondering what the number of species of the frogs and finches can tell us about their form of evolution or their evolution patterns. I'm positive this is happening everywhere, we just don't even see it. Some other similarities in the environments of the two creatures makes me wonder if the fact that the two lands were not populated(for the most part) contributes to the form of evolution that occurs, or how quickly it occurs. Hopefully what I think is true: the "survival of the fittest" will decline the amount of species of frogs across the Western Ghats, but the fittest species will continue to live on in that particular environment. Another possibility could be that some or all of the frog population have began to migrate to be able to adapt where they have a better chance at surviving. Overall, this is a very interesting find, and I am curious to see what is in the future for these special frogs.
ReplyDeleteThis really fascinated me, this behavior in frogs in not 'normal', for most frogs don't do this. Usually male frogs make a noise to call for a mate. Now, due to the noise of the waterfall, these frogs cannot be heard, perhaps. After all their unsuccessful attempts to find a mate, they started 'dancing' in order to find a mate. When this started becoming successful, the frogs started to do this instead of noises, as it was now best suited for their survival.
ReplyDeleteThis article and video relates to evolution because the frogs have made an adaptation based on their environment. They changed their ways to suite the environment around them. Since not all frogs do this, I'm assuming that they learned to do this, and their oldest ancestors did not do this. Because, if their oldest ancestors did this, a lot more species of frogs would be doing this "dancing".The dance they do is a sort of mating call. It attracts females so they can mate with them. These frogs are in danger, and we need to save them. We might be able to learn much more from these species. We should study them and learn what other adaptations they made, if any, and apply that to evolution.
ReplyDeleteUpon watching the video, it became aparent that this particular characteristic of "dancing' must be the result of natural selection. At some point, a frog must have undergone a mutation which created the urge for spasms or the stretching of specific limbs during the mating season (or all seasons for that matter). This trait would have been extremely helpful because mating calls were not very effective. Since this allowed for better mating, the trait became preferable and was passed on from generation to generation. On the other hand, this could also be the result of behavioral isolation. The calling did not work, so they resorted to dancing so that they might still efectively reproduce.
ReplyDeleteIts an odd way to attract the ladies, the way the frogs stick out their legs. I wonder what it would be like if guys did that to girls, it would be very strange. Anyway, i hope the scientists can document all these frogs. It would be a shame if we miss a new species of frog because we ran out of funding or time. I hope we can find many more new frogs, and see if there are any differences between them and thew ones we already found. The more differences they have, he farther they will go in the classification scale. Who knows, scientists could be on the verge of a evolutionary breakthrough! (though I doubt it). I wonder, are the frogs the only animals that "dance"? I would like to see other animals like a giraffe dance the way these frogs do. A little weird, but I think it would be entertaining. I think these frogs are in danger of being eradicated, and I hope we can do whatever we can to save these little fellas
ReplyDeleteThis video relates to evolution because the frogs have adapted a new way to attract mates, that will actually work in their environment. I think they do their dance because it is easier for a female to see them. In the environment, the frogs may not be able to hear the singing-mating call. It relates to classification because probably somewhere in the past groups that the frog is related to did this leg mating call. They are in trouble because of the river, causing them to fall in and die.
ReplyDeleteWhat an amazing evolutionary adaptation! That is a perfect example of sexual selection. The females chose their mates based on an appearance or behavior. I would have loved to see one of those frogs doing their little dance. It's very sad that some of those species are going extinct before we can document them. I believe it would be a great idea to teach our frogs to dance so they could carry on the tradition. I also how recently the mutation occurred that made the frog want to "dance". I suppose if a mating call was not heard that the frog could do that to attract the mate without any sound.
ReplyDeleteIt's truly amazing how the frogs were able to find a way to attract a mate next to a noisy waterfall like that. The fact that these frogs realized that they couldn't hear each other and found another way to get each others attention that they all understood is amazing. Using a dance to replace a mating call is a smart move on the frogs part. I don't think these frogs are in danger. As long as they can see each other, they will be able to mate.
ReplyDeleteI think this article is a prime example of evolution. Since they can't hear each other over all the noise they decided to start dancing!. As interesting as this may be it can also have its downfalls such as the female frogs can't see the male so she just kinda moves on. They need to come up with a way that can be heard over the sound. Because vision isn't always as good as hearing
