  • Standing athwart history and pushing it back

    Recently The New Yorker had a long feature on the German social experiment from the 1970’s to early 2000’s which placed homeless boys in foster care with pedophiles. The whole […]

  • It’s science, not math

    My post below elicited this response: Here are a couple of cases which seem to defy easy classification. A “chimera”. This is a person who has cells derived from two zygotes. It can happen if two fertilized eggs merge very early in development. Th…

  • Sex & sport

    The New York Times has an article up on a new I.O.C. ruling on who can compete as a woman. Basically they look at testosterone levels. This seems a different tack than cases where women were banned from competing as women because they had a male karyto…

  • Porn, a new age, an old age, and all that

    I’ve been commenting on internet porn for nearly 10 years. One reason is that as someone who graduated high school in the spring of 1995 I’m probably in the very last cohort of American males for whom pornography was an item subject to scar…

  • Iraq: the model that wasn’t

    The magazine Foreign Policy recently had a “sex” issue out. This issue is particularly famous for Mona Eltahaway’s jeremiad against Arab male culture, and their attitudes toward women. Over at bloggingheads.tv Charli Carpenter express…

  • Understanding ethnic biased sex slavery

    Recently on the NPR show Here and Now I was introduced to the concept of ‘loverboys.’ This is a specific phenomenon in the Netherlands were older males target schoolgirls, and entrap them in relationships where these girls are prostituted out (there are repeated references to group sex). Even before it got to that part I…

  • Promiscuity and vaginal bacterial diversity

    It’s a fun fact that there are an order of magnitude more bacterial cells in your body than your own cells. Not only that, it’s well known that we wouldn’t flourish, let alone survive, without our gut “flora,” which digest material which would otherwise pass through out system. Not only are microbes good for us,…

  • Everything I didn’t know about sex

    The Pith: The primary reason for the pervasiveness of sex among complex organisms is to maintain genomic integrity, not to increase genetic variation.. I just read a very strange article in the journal Evolution, Sex reduces genetic variation. In it th…

  • The Rights of Woman

    All the talk about the ladies, I poked around The World Values Survey. I was going to post the results in relation to “women” related questions, but I’ll leave it to you. I will say this: – Muslim and East Asian societies are the least forthrightly supportive of female political and social equality – There…

  • Sex with thee and the last woman

    A quintessentially sexy topic in biology is the origin of sex. Not only are biologists interested in it, but so is the public. Of Matt Ridley’s older books it is predictable that The Red Queen has the highest rank on Amazon. We humans have a fixation on sex, both in our public norms and our…

  • Polygamy and human evolution: maybe it’s agriculture

    Eric Michael Johnson has a fascinating piece in Psychology Today, Sex, Evolution, and the Case of the Missing Polygamists. I want to spotlight a few paragraphs: Keep in mind that in terms of interpreting such genetic evidence we are of necessity confined to a fairly recent time depth (and remember, by “recent” someone like me…
