It was the 11th meeting of the Empiricist League, a kind of ad-hoc, small-scale TED Talks for scientists and the New Yorkers who adore them. In the back corner of the room, Christian Rudder sat by himself at the bar, nursing Stephen King’s “It.” Rudder, the 39-year-old president and co-founder of the online dating site OKCupid, had come to deliver a distilled version of what he’s been working on for the last five years.

In 2009, Rudder started OKTrends, an in-house blog for OKCupid, as a way to attract new members to a site that was nearly out of money. The posts covered such topics as the best camera angle for a profile picture and how people lie on their profiles — the mysteries online daters wonder about. Soon, Rudder’s insights and wry wit were attracting millions of views. Savvy book publishers took note. And then Rudder delivered the punchline. Biology and sexual orientation. Biological basis of sexual orientation. CONTACT: Stanford University News Service (415) 723-2558 Biological basis of sexual orientation STANFORD -- Research into the biological basis of sexual orientation "presents a clear double message.

Yes, genetics plays a part. No, it is not all genetics," Dora B. Goldstein, professor emeritus of molecular pharmacology, told the audience that attended the first in a series of public lectures sponsored by the Medical Center's Lesbian-Gay-Bisexual Community on March 9. "This shouldn't be too surprising because that is what all kinds of behavioral studies indicate.

In her noon presentation, Goldstein reviewed relevant research in a number of different areas: population studies, family studies, twin studies, genetic research, childhood behavior, and brain differences. Study: Science Can Change the Sexual Orientations of Mice - James Hamblin. By altering serotonin in their brains, researchers caused female mice to prefer to mount and sniff the genitals of other females. twoshortplanks / flickr PROBLEM: A Gallup poll last week said that 47 percent of people in the U.S. understand sexual orientation to be congenital.

In 1978, that number was only 13 percent. Here's how Americans have tracked over recent decades in response to "In your view, is being gay or lesbian something a person is born with, or due to factors such as upbringing and environment? " As people's understanding changes, science is working to clarify what "born with" means.

Homosexuality May Start in the Womb. From a strictly Darwinian viewpoint, homosexuality shouldn't still be around.

Homosexuality May Start in the Womb

It isn't the best way to pass along one's genes, and to complicate the picture further, no "gay genes" have even been identified. According to a newly released hypothesis, the explanation may not lie in DNA itself. Instead, as an embryo develops, sex-related genes are turned on and off in response to fluctuating levels of hormones in the womb, produced by both mother and child. This tug of war benefits the unborn child, keeping male or female development on a steady course even amid spikes in hormones. But if these so-called epigenetic changes persist once the child is born and has children of its own, some of those offspring may be homosexual, the study proposes. Evolutionary geneticist William Rice of the University of California, Santa Barbara, felt there had to be a reason why homosexuality didn't just fade away down the generations.
