Other animals do too. Great talk, but regarding animals, it does not look this person knows much about them, probably, it would be better not to make comparisons between animals and people in such situation simply. Animals are very caring and support even those not of their kind if needed, there are many examples for that.

Pretty sure I saw a documentary showing that domestic cats living in feral colonies share care of nursing kittens as well..

The most annoying thing of many, if not most, popular treatments of evolution is this idea what selection optimizes everything, in effect replacing god. I don't know if you've ever tried to convince someone that some trait X might not be an adaptation, but it's hard.

I do it all the time. Selection might optimize, but genetic drift is sure going to mess things up. Your mind and mine are again intersecting on these issues. I've been meaning to write more about it, but perhaps we'll have to write a paper together (again). I would consider it a service to inform people who make use of evolutionary theory. As much as I'm sad to see adaptationism run amok within biology, I would see it as more helpful to let non-biologists know about other mechanisms. Biologists and non-biologists unwittingly make use of selection all the time. Have you read Mutation-Driven Evolution by Masatoshi Nei? See my post on sexual selection in humans for a gentle reminder that selection is not the only evolutionary mechanism.

I thought about writing a paper on the subject in Evolution: Education and Outreach (open access and read by many educators), it's still on the long list of things I should do. If you want to do it, I'd be happy to help, especially if you take the responsibility of first-authorship. For various reasons, I'm not a particularly skilled teacher and I never taught evolution. I'm sure you would be more qualified to drive such effort. And I think it's an important, albeit difficult, fight. A good friend published two papers on perception of randomness, and it's incredible to see smart, mathematically skilled people, struggle so much with randomness. I didn't read Nei's book but I'm familiar with his work on the subject. His 2005 paper "Selectionism and Neutralism" makes a pretty strong case for the importance of mutations.
