Being gay isn't genetic, but it is biological?

At least, according to io9's understanding of an upcoming study.
A team of international researchers has confirmed that there's no such thing as a ‘gay gene.' But that doesn't mean biology is off the hook in terms of explaining why homosexuality exists in the human population. It's not about genetics, say the researchers, it's about epigenetics — the process in which the expression of DNA is influenced by any number of external factors. And in the case of homosexuality, these factors are happening inside the womb.
I don't pretend to know anything about epigenetics, but I'm interested to learn, and I'm interested to see what reactions the rest of the scientific community (and the community at large) will have to the study once it's released.

  1. Interesting, because external factors *in the womb* are still factors from Mom, no? Either way, I heartily believe that for many if not most gays it is biological.
