      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

      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

          Are the only results that are positive in this direction from samples of mostly white people in industrialized nations? Extrapolating from contemporary pops w/ massively reduced fecundity and male variance vs ancestral past is dubious... https://link.springer.com/article/10.1007%2Fs10508-007-9191-2 …pic.twitter.com/Q3T98WHvcb

          Not at all. The effect was also found on Samoa:https://link.springer.com/article/10.1007/s10508-009-9576-5 …

          There may be a significant effect, but it is never large enough to outweigh the 0.2 < γ < 0.7 fecundity in HS males. Also the results may be influenced by measuring open and active HS males, which may fully explain the slightly greater fecundity of relatives.

          Does no one else suspect that the 0.2 < γ < 0.7 fecundity measures are an artifact of contemporary research that might not have held in more heteronormative cultural environments, say before the 1960s?

          Blanchard 2012 is negative result, and the methodology better and the sample size 4784 versus 240 for Campera's clinic !
