comment How did aquatic dinosaurs go extinct?
now that I read the question again, I may have misunderstood it. I have to make a pro forma edit before I can remove the downvote. But I have to wait for the peer review.

comment How did aquatic dinosaurs go extinct?
Interesting info, but the aquatic dinosaurs went extinct millions of years before the meteor. So, this doesn't answer the question.

comment About animal ecology and one view of this in science fiction
I agree that the question is formulated very badly, has a strong philosophical bent, and could be interpreted in different ways. But there is a surprisingly simple answer: all interpretations I can think of are false. Animals do not strive towards maintaining environmental balance, neither consciously or unconsciously. The existing balance is a byproduct of the sum of their independent non-cooperative actions.

comment How are arms different than legs?
Why do they have to be defined physiologically? It is a matter of common everyday language, and human language is generally inconsistent and full of "because we've always called it this way" and "because they look similar" reasons. Do you have any example of any scientific research which divides appendages in "arms" and "legs" and proves results which are true for the one and not for the other? Maybe if you got to stuff which is about gripping, or bearing weight, but then you are back at the informal language level.

comment Why does botulinum toxin seem to be more dangerous to humans than to other mammals?
From a food safety point of view, you don't get botulism from "carcasses" (meat). Common botulism vectors are plants, especially the parts growing around dirt (making homemade garlic oil is a really bad idea), and honey (a danger to infants, adults can stomach the spores and they can't form a colony of living bacteria in honey). So, if there are animals which come frequently into contact with botulism, they aren't vultures. Actually, I might have to write an answer about that...

Polar bears have hollow hair shafts? Forget alpaca and mink, I want to knit polar bear yarn!

comment Does human eye lens have a magnification of its own?
What do you mean, "bigger/smaller than what they actually are"? What is your definition for seeing a thing in an absolute size, because I can think of none that makes sense? (And no, the human eye does not work like a camera, so saying that when the image of a 2 mm worm hits a 2 mm stretch of neurons in the retina you have "actual size" doesn't make sense, because it doesn't matter for your visual perception).
