    The faces of gay men are more feminized and rated as more attractive than those of heterosexual men by both sexes. http://www.tandfonline.com/doi/full/10.1080/00918369.2017.1411692 …pic.twitter.com/OtW5cJY9Qa

        What twin studies say about the heritability of homosexuality, and why the data aren't yet good enough to draw strong conclusions. And I would love to bet my money on the larger concordances. https://www.amazon.com/Gay-Straight-Reason-Why-Orientation/dp/0190297379/ref=sr_1_1?s=books&ie=UTF8&qid=1512140795&sr=1-1&keywords=straight+gay …pic.twitter.com/ZYaVbtFkDl

        They - unfortunately way too few - examples of homosexuality in identical twins reared apart are also very interesting. https://www.amazon.com/Gay-Straight-Reason-Why-Orientation/dp/0190297379/ref=sr_1_1?s=books&ie=UTF8&qid=1512140795&sr=1-1&keywords=straight+gay …pic.twitter.com/kR3mft4WSV

        How strong is the data on the greater fecundity of relatives of gay men?

        The trend has been replicated several times http://cshperspectives.cshlp.org/content/7/4/a017657.full … and I haven't seen a single negative result. Still I would love to see a good meta-analysis. Same goes for concordance in identical twins. I bet it is higher than assumed.pic.twitter.com/xGbUbbNYdS

        By the way, if prenatal hormonal feminization was the cause of homosexuality, concordance in identical twins would have to be higher, as most (70%) share one placenta, the same hormonal milieu.

        I don't believe that natural selection would let stand a mechanism that drastically reduces reproductive success dependant on random, idiosyncratic experiences - at least without a compensatory benefit.

        There is a theory that gayness in men increases the success of the greater family unit, as they help raise kids and are often able to better relate to both men and women.

        And that is what I do not buy. Natural selection would eradicate any mechanism making sexual orientation (and thus, fitness) dependant on idiosyncratic events.
