Scientists discovered that many genes – not just one – influence sexuality. But so does the environment, making it impossible to determine whether somebody is gay based on there genetics alone. Nearly half a million people participated in the study, which was published in the journal Science on Thursday. One of the key findings was that five genetic strands are closely related to homosexual behavior, with two of the variants distinctly found in men.
What do the findings prove? It confirms what we already knew: that same-sex sexual behavior is a completely natural phenomenon.
