Picture an “animal” in your mind right now. What does it look like? A dog? A lion? Maybe a sloth, pangolin, naked mole-rat, or even just a human? There’s a good chance that you imagined a mammal, which is understandable since we are mammals after all, but there is so much more animal life out there! Today, we’re going to try to figure out what that “average” animal would really look like - its size, what it eats, how many legs it has, if it even has a head, if it flies or walks or swims, you get the idea. And what we’ll find might just surprise you, or maybe not, they’re pretty common after all! But what we’ll also discover along the way is that what we think of as average is based on what we KNOW and there is so much animal life still to be identified. So maybe if you’re watching this in five years after you’ve identified a ton of new nematode species our answer will be totally different!

Somewhat random aside: I've been stuck thinking about the original 'Sonic the Hedgehog' games lately. All the animals that you save from the robots are either mammals or birds (except for one level of Sonic 2 that has turtles) but the majority of the robots that you fight are modelled after invertebrates or fish. It's a weird dissonance where it's a story of nature versus technology, but the view of nature is skewed to being very mammal-centric. It's a bit weird to say about some old platform games, but it feels like a pertinent example of how some people view animals?

@SpiderdayNightLive 3 жыл бұрын

Yeah, it’s a problem called vertebrate bias, and it doesn’t just show up in video games-it’s a big issue in zoology research too. More time and money is spent on vertebrates (which as we saw are a very tiny % of all animals) than in inverts, even though there are so many more of them.

I staggered too, but looking at it now, I think I see it. Its "knees" are bent backwards and are in-between the camera and its butt. The joint connecting its red little stubby toes is an ankle? Then we go towards the butt for knees? No wait... The knees are the ankle, and the thing I called the ankle is where the toes join the feet? Idk. But it looks like it has 6 limbs probably because some joints are lined up like I said, butt-joint-camera

That freaked me out too at first! I think what appears to be 2 sets of back legs is just its legs folded back all the way and then its feet pointing outwards. If you look closely you can see its "knees" tucked against its bum.

I must say I love the content of this channel and I love zoology (i'm a biologist myself) but I shall make one critic: It is hard to not be Homocentric (thinking the human is the apex of evolution, or "the most evolved life") when you guys represent human on this sort of scales like in 1:57

@robertiktomi8498 3 жыл бұрын

Well, they said "diverged latest"; which animal species (other than domesticated forms) is much younger than Homo sapiens ?

@SpiderdayNightLive 3 жыл бұрын

Hey Leandro, thanks for the feedback. One of my goals in the series is to break away from homocentric depictions of evolution, which is why we showed that as a phylogenetic tree and not the linear scale that you are probably familiar with. We say that humans are a late diverting group (H.sapliens is about 200k years old which is not much) not that they are more evolved. Keep watching, I think you will be pleased with the upcoming episodes.

@Mobin92 3 жыл бұрын

Why does the number of species matter and not the number of individual animals? Just because you can categorize beetles into many different kinds, doesn't make them more important.
