Couldn’t hack living in a tough neighborhood, full of Homo Sapiens.
I had heard that the interbreeding of Neanderthals with Homo Sapiens caused the Neanderthals to die off.
I remember from All in the Family, a Homo Sapien is a killer fag, isn’t it?
Bingo!
Competition. Survival of the fittest. They lost. But their genes live on.
Life!
