Implications of Evolutionary Theory for Human Homosexuality

Universals

As pointed out above, more complex animals, seem to add new, more complex associations with homosexuality to the already existing repertoires of simpler species. Yet they still retain the older repertoires. We should, thus, find evidence of these older repertoires in humans. This makes sense in terms of the "tinkerish" econony of natural selection. As modern neuroscientists have pointed out (Damasio 1994; Vincent 1990; LeDoux 1996), the human brain is constructed in "layers." The phylogenetically inner layers are more conservative, varying less from one species to the next, in conformity with the great dictum of natural selection: "If it ain't broke, don't fix it".
