Talk:Suicide and evolution

From Wikipedia, the free encyclopedia

Article needs work: only focuses on one researcher, tone is not encyclopedic, some sections are repeated.

I've always thought depression and subsequent suicide were forms of altruism, the results of kin selection. An animal becomes depressed and lethargic when rejected by peers or potential mates, and puts up less of a fight against predation. In doing so, the animal protects its kin from predators and removes its (inferior) self from competition for resources. As such, animals don't really have opportunities for suicide unless they have no natural predators, like man. Article should definitely cover suicide in animals, if it exists. — Omegatron 04:10, 12 December 2007 (UTC)
