Wicked doc on the science of homosexuality. Take that, bigots!
We’re starting to piece together the science of Epigenetics, which looks at how cell differentiation occurs during development. Think of it as a way for us to understand how different genes can be expressed even though there’s been no real change in the organism’s DNA sequence. It’s extremely complex and I won’t even pretend to understand what it’s all about, but one thing is for sure: it’s probably one of the most exciting fields of study in biology right now.
One of the ways that this science is being understood is by comparing identical twins, and as you can see from this video, something as simple as a hormone’s effect on the development of the brain may be entirely behind homosexual preferences. I think it makes sense; I mean, we are all female at some point, and if it wasn’t for our bodies producing testosterone, we’d still all be females. Why are we surprised when every once in a while, a dude is born who likes other dudes? Seems like it would be something you would actually expect to happen regularly in nature…which it does. Can we lay this issue to rest now?
