    heh. that’s weird/annoying.

    if you’re interested, you can prolly get the gist of the whole story by reading the guy’s comments (he responded to a lot of questions in the thread).

    @eugenicist – “I bet this isn’t that uncommon….”

    maybe. but this guy claimed it was an ongoing relationship for, iirc, 12 years (maybe it was 13). that i don’t think is so common. i mean, it wasn’t just a little pre-teen experimentation. not just playing doctor, you know?

    Yeouch! I didn’t catch that. I just thought they’d had a mildly sexual relationship (fooling around) for about a decade. Banging 2-3x/week for 13 years is something differerent.

  4. maybe these two didn’t overcome Westermarck effect, but just did not develop it naturally, somehow

    yeah, that’s probably it. there’s probably some variance with the westermarck effect, too, like everything else in Life — nothing’s 100% in biology. that would be unnatural.

    one point — they apparently shared a bedroom as teenagers. maybe a bad idea….

  6. Well, the Westermarck effect probably isn’t an absolute. Certainly, there are plenty of historical cases of incest (historical anecdote suggests that incest was fairly common within Ancient Egyptian royal families), though whether it was usually consensual or not is up for questioning. While I personally can’t imagine being attracted, in a sexual way, to any of my siblings, I also can’t imagine being homosexual. But that doesn’t mean homosexuality doesn’t exist, even though it would, at least in theory, be maladaptive in the evolutionary sense (as would a strong desire to have sex with someone who probably carries similar harmful recessive genes as oneself). Apparently, a more-common-than-you-might think problem with reuniting opposite-sex siblings separated their whole lives is genetic sexual attraction. Presumably, there is some adaptive advantage to reproducing with people who are somewhat similar to oneself, though not so closely related as to create serious inbreeding depression. The Westermarck effect probably evolved to prevent this tendency from causing people to bang siblings, resulting in children with serious double-recessive disorders.

  7. Georgia, I believe we are starting to have this kind of problem with sperm-donor babies growing up and then realizing that they are banging their half-siblings. Yikes!
