This is an extremely fascinating talk. Talk nerdy to me is refreshing because it is a civil conversation. The topic of bisexuality come up and the 'gay gene.' Ricahard Dawkins, "...homosexuality has a strong genetic basis, based on multiple studies that point to heritability of LGBT identification and behavior." Breast feeding leads to homosexuality?
My last post, The Gay Brain, really got some of you talking. The central thesis of the video was that even though scientists have yet to identify the "gay gene," the vast consensus in the scientific community is that homosexuality has a strong genetic basis, based on multiple studies that point to heritability of LGBT identification and behavior. Many scientists believe that there is not just one gay gene, but in fact a multitude of genetic markers that are either switched on or off by a complex dance of epigenetic and environmental factors. Either way, it cannot be denied that being gay is rooted in one's biology.
At the end of the post, I asked what all of this means from an evolutionary perspective. Chosenfew79 left a comment that summarizes the questions that were raised by many of you:
