Was Bisexuality the Original Norm?

In his book, Bagemihl describes homosexual activity in a broad spectrum of animals. He asserts that while same-sex behavior is sometimes found in captivity, it is actually seen more frequently in studies of animals in the wild.

There's an interesting concept - humans are an entirely domesticated species.  There's a lot of homophobia and pro-"traditional" family approaches out there.  Well, there's evidence to suggest that when time was, it was villages that raised children - not nuclear families. 

What if it's the homophobes that are impeding nature, going against God's programming by trying to impose heterosexuality?
