In evolotionary biology the "why" question can be tough, because in that context you often ask "what made natural selection force this animal into becoming this size". I guess when eating large quantities of small organisms then size matters, higher net gain in energy, in a fashion that couldnt be competed out with smaller whales having less need to sustain themselves but also having a relative drop in energy source as well. Then you got the aspect of potential predators etc, a just-so story.
Very well done ..fast and informative. I have some friends id recommend this kind of teaching to...seriously , I know lots of adults who don't know things like this anf don't have good ability to concentrate for long periods of time , who had problems learning at school when young. I would definitely send videos like this one to them. Thankyou for posting it here.
A question for people who study biology. Is there such a thing as a size trap in evolutionary terms? It seems evolution favours growing bigger as a defense against predators and for other reasons. But bigger animals need more food and when a disaster happens, like a great extinction event, the bigger species generally can't adapt and die out. Which means big species like the BW or T-Rex dominate the world in their era but eventually tend to die out becoming evolutionary dead ends, failures. Or am I wrong?
1503nemanja Bigger animals means bigger lifespans, smaller (rabbits, bacterias...) have smaller lifespans, so they need to reproduce more than the bigger ones, so, we have to sides of the coin, if you're bigger, you'll live more but reproduce less, evolution don't "recommend" to be bigger nor smaller, that's why bacterias keep existing and whales too, there's no dead end, if a animal can eat enough to maintain itself and reproduce, it's a success, if you can't, well.....you're pretty much dead.
You need to remember that evolution is blind, and depends heavily on the environment. To say that those extinct species are failures is saying that they had a purpose which they didn't fulfill, which of course is not true. Remember that 99% of species that have lived on Earth are extinct by now. If there was a purpose, even though there isn't, it would be to pass the DNA to future generations, and DNA transcend organisms and species, so... Not much of a big deal if some species go extinct.
Actually, i love the way they express information to us. Even i'm seventeen, i still prefer being inform by animated film like this to listening hours to boring teacher or documental film. Though, i cant understand all of the words they said, but at least i got enough knowledge. (If there's any grammar mistaken, please correct me. )
She needs to narrate more. She has a very relaxing voice that's easy to listen to. Also, neat information! :D (I mean, I knew most of this as my field of study happens to be marine biology, but some facts I didn't know, so...neat!)
Damned, please do subtitles! A very interesting TED Talk, but I'm not an English native speaker and couldn't understand everything. I want to understand everything!
Wow Asha it was lovely to watch this clip well done :) my 2 little nieces in UK are going to love these videos they are 5 and 7 and are sooo hungry for information which is easy to digest and interactive like this is.
This channel has always been for kids and young adults. I watch it as an adult because it seems to be able to fill in some of the gaps in my education. Watch it and enjoy it but please stop moaning about something that really is a non-issue.
TED-Ed can you make a video about krills ? how can a normal person help increase their numbers? And thank you so much for all those wonderful informative videos ❤
Because Krill feed on phytoplankton, little microscopic organisms that flourish in upwellings of deep waters at the Antarctic convergence. These upwellings are full of nitrate and phosphate that act as a fertilizer for the phytoplankton. When you combine that plus the 24 hour light they receive in the Antarctic, it allow them to flourish. Krill are large enough to be eaten by large animals, so animals get a large amount of energy from the kill because it's close to a primary food source.
What did the blue whale look like before they do now? What caused the whale to evolve into its current form? I found the size of the esophagus very interesting. Why would it be so small on such a big animal? It's questions like these that you can ask about every animal and plant that gives you pause while contemplating evolution.
LOL. I could not stop laughing at the whale. and on top of that I actually got a blue whale puppet for Xmas. I wasnt expecting a puppet / plush but I love it
I actually love the way they express information to us. Even though I'm seventeen, I prefer being informed by animated films such as this over listening to a boring teacher or documentaries. Even though I can't understand all of the words they said, I at least gained some knowledge from the video. Sorry, I'm not trying to be a "Grammar Nazi" I was just trying to fulfil the help you asked for. Your English is quite good for a 17 year old, Vietnamese boy. :D
They are not. Whales, as well as dolphins, are mammals like us. They are warm blooded, give birth to live young, have hair (not a lot, but it's there), and breath air. Fish are cold blooded, (generally) lay eggs, have scales, and breath water through gills. A good tell is to look at how their tail fin moves. Fish, like sharks, move their tails back and forth horizontally to swim, while whales and dolphins move their tails up and down vertically.
Perhaps watch the video again? It explains how the blue whale's ecological niche of krill dietary specialisation encouraged a huge body size in order to maximise the efficiency of it's caloric intake versus expenditure. If you're interested in what the ancestors of whales looked like, we have an impressive fossil record, and data from molecular phylogeny continues to give us a more detailed picture of the past. It's no good asking questions if you don't put any effort into finding the answers.
"So why isn't there a spectrum of sizes?" is what he is asking. You have to explain why the smaller ones were less likely to reproduce. The videos suggests that whale size is the most efficient for how they eat so smaller ones would be less likely to meet energy requirements. Also, smaller ones might have been preyed on more. Population change through evolution doesn't just happen because it can. It happens because the change makes the individuals more likely to reproduce so their genetics sp
so you would prefer to not say what you dont like on a video so they do it again and if everyone hates it, it will receive less views which will hurt the maker and they wont be able to make free videos. so im just helping them
guys each video is made by a different person in TED so therefore the style of each video may differ based on what audience the producer want to aim at..;.
It seams diet plays a large role in animal evolution Thanks so much for putting this together very informitive

Well we've got to the point where we both agree and I don't think there's much to say now. Thanks for the talk, I enjoyed it and I hope that this problems solve as quick as possible to prevent what you just said in your last comment. Once more, thanks for the conversation.
emotions are thought to be evolutionary characteristics that means on a basic level we react in a specific way which, in evolutionary terms, helped us survive - e.g. love -> we feel love as it gives us a feeling of wanting to protect those we do, which where group living is involved, means we were much more protective of our young for example and therefore helps survival
Love is a concept based on chemical feelings; this concept is the connection, or feeling of a connection, to another being or object that makes one feel a part of the external entity and as a result a mentality of dependence may form; this is love.
I just googled this and no one knows why they are so big. If anything this video gives a reason against their size - at 4.23 it says bigger = less efficient. So the video not only doesn't explain why they are so big, it makes their size even more mysterious!
Yeah the heart is NOT the size of a small car. It's maybe half that size if not a bit smaller, and a child can't crawl through the arteries. Given that the date of this video is in the year 2013, I won't fault anybody, but a blue whale heart has recently been preserved and seen for its true size.
I Super mega really like this channel, Theres so much cool and fasinating information and this video looks cool bc this is like puppets or like an episode from sesame street

Lmao same question
Does the animation remind you of don't hug me I'm scared?
no, because it's not animation
yes especially when it's skin rolled up
yeah
no. it doesnt even remind you a bit. obviously it reminds to MUPPETS.

This looks like an episode of Sesame Street
That was the point.
It does actually.

This is great. Very beautifully made. Thanks for sharing it with us!
I find it a bit strange how kidsy this is compared to most other videos on the channel, but hats off i'd still watch the heck out of this.

bats can live 40 years and lions 14 years. it's not so simple.
Chiron Wode Yes, there's cases where is different, but if you see them in general, bigger=larger lifespan.
You need to remember that evolution is blind, and depends heavily on the environment. To say that those extinct species are failures is saying that they had a purpose which they didn't fulfill, which of course is not true.

The blue whale's mean lifespan is several times longer than humans like for several centuries.
The puppets were hilarious. I love to laugh.
Its the greatest animation on Ted-ed. Thanks

thank you.. Just thank you. I've always wanted to know this.

how can a normal person help increase their numbers?
And thank you so much for all those wonderful informative videos ❤
you didn't go to math class didn't you?
As a Sri lankan I feel sooo proud about miss Asha de vos❤
What a beautiful video!
Asha has done a great job too.

This animation is amazing
Are all those puppets really neccesary?
Absolutely.
Whales also eat sharks.
Masashi Ng the throat is too small to eat even a human baby
thye can only eat the size if a grape fruit
Whales are much bigger than sharks. Whales are the ocean's apex predators.
You should make more videos like this...
I sometimes just think if I'd have another chance to live in my next life, I would love to become a blue whale.
TEDEd is amazing. I learned so much
great video, just wanted it had the links of the research so then i could learn more
LOL. I could not stop laughing at the whale. and on top of that I actually got a blue whale puppet for Xmas. I wasnt expecting a puppet / plush but I love it
Wow. There are so many 'documentaries' that are so poorly narrated on UA-cam. Asha is 100% on the other side. This was well done.
I wasn't expecting puppets to be used but anyway it's still as entertaining. :)
