2: 23 - I don't get it, how could carnivores, in the sense of animals eating other animals, exist for generations before animals eating other things? That would be like a species surviving on nothing but cannibalism, like a biological perpetual motion machine. Did you mean the first animals were (at least partially) eating other microorganisms that weren't plants?

I mean, if you're made of meat then it makes sense to eat other things that are already made of meat 8D Kind of like snakes: if you're a noodle with a head then the optimum shape of food is also noodle shaped (the head is optional)

I find it hard to believe that the first animal ever started by eating animals, because it can't be the start and eat others of it's kind. Like, wouldn't eating other animals have to start long after the first animal?

I'd be interested to learn more about taste and tastebuds. I've always wondered what animals think about their food, or whether they enjoy it. If animals DON'T really -taste- their food, then why do we?

It feels weird that carnivory is much more ancient and common throughout the animal kingdom, since the food chain has to be linked somehow and we can't just have producers and consumers operate separately.

oof that phylogenetic tree. i definitely wrote a paper for invertebrate zoology class in college arguing that porifera is more basal than ctenophora lol oh well

4: 37 -. and has very few nutrients and calories- Isn't wood technically high in caloric energy? If animals can't extract it all that's another matter.

I am pretty knowledgeable on this subject (I make videos on anatomy and cellular biology) but I still learned so much on this video lol. Good work!
