I'm skeptical of (The Huffington Post)
Homosexuality as a deterrent to overpopulation is a hypothesis proposed by scientific researchers applicable not just to homo sapiens, but throughout the animal world.
That is a strong claim, it’s corroborated by the entire article (and elsewhere, it’s a pretty well-known and widely repeated claim) and there’s good reason to be sceptical of it.
What is wrong?
Perhaps the claim is not a notable one, or are there other reasons?
