incest

Research on the subject suggests that somewhere, somehow our squirmy reaction to incest can be expressed genetically. Because of natural selection and all that blah blah, it's thought that there exists a biomechanism that triggers incest avoidance in humans. Well, it looks like some very bold scientists have found a solid starting point for furthur research: lemur hoo-ha's. Christine Drea, Marylene Boulet, and Marie Charpentier from Duke University carefully obtained genital gland secretions from 17 sexually mature female ring-tailed lemurs. Side note: most species of lemurs live in…
The New York Times has an article on cousin marriage that's up. Here's some important bits: Shane Winters, 37, whom she now playfully refers to as her "cusband," proposed to her at a surprise birthday party in front of family and friends, and the two are now trying to have a baby.

The couple -- she is a second-grade teacher and he builds furniture -- held their wedding last summer on a lake near this tiny town in central Pennsylvania. But their…
The Hapsburgs are one of those royal families who are relatively well known, and in the minds of the public are to a great extent the emblems of the downsides of inbreeding. To painting to the left is of Charles II, king of Spain, the last of the Spanish Hapsburgs, and an imbecile whose premature death at the age of 39 ushered in a period of dynastic chaos which led to the War of Spanish Succession These conflicts between France and other European powers were one of those turning points in history, a sad capstone to the long reign of the Sun King, Louis the XIV. France's position as the…
Over at Secular Right I point out that Romania is set to decriminalize consensual sexual relations between adult first-order kin. That is, incest. There are a few angles that this story offers. First is the moral-ethical one. From a rational individualist perspective how reasonable are laws which ban consensual sex between adults who just happen to share distinctive genetic information? The love that dare not speak its name because of alleles which are identical by descent? Of course all this rational talk is irrelevant for most people. Incest is gross, repugnant and immoral. Not because…
