When We Think Like Karl Pilkington

In my last post, I dismissed a common objection to the study of the genetics of behavior, political or otherwise: complexity—as in, development is too complex for genes to affect behavior. I hope that I managed to convey the certainty with which scientists have answered the question “does genetic variation affect behavior?” in the affirmative. There is a considerable body of evidence substantiating this claim, from the most basic (centuries of animal husbandry by domestication) to the most extraordinary (myriad knock outknock downknock in, and transgenic experiments). We are no longer dealing with correlations alone but with unambiguous cause and effect: polygamous voles turn monogamous, anxious mice relax, and heterosexual fruit flies become bisexual, all at the turn of a gene or three.
