However, overpopulation triggers such a strong migratory response, that it will drive herds away from the overcrowded area, without any regard of dangerousness of the terrain crossed while migrating. Causing them to fall off cliffs, drown in rapids, and similar deaths that could be seen as suicidal.
I feel like you believed what you said the first time, and then looked up 'Lemmings' on Snopes when you found out you were wrong. You claimed to be a biologist to give your words in this thread weight, but you actually barely scraped through high school biology with a D, didn't you?
that particular point was also flawed because it would imply that homosexuality would increase as a population became overcrowded in order to decrease reproduction, which i have never heard of happening. I don't see any reason to go insulting martinuzz though, this isn't really the sort of thing someone with a degree in biology usually gets to learn a lot about.
but yeah, preventing overcrowding problems is not among the things i've seen scientists say may make homosexuality adaptive for animals.
