Despite the trollish nature of the post, it did remind me of something. The biological anti-incest drive is actually not triggered by the relatedness of individuals, but the amount of time you spent with them as children. I believe this was discovered in communist orphanages, where children refused to marry those they had been raised with. Incest between brothers and sisters who were not raised together is actually MORE likely because of all you're likely to have in common with each other.
You can also see this effect in High School classes that are small enough that you all know each other . . . and stable enough so you've been in almost every grade together. Sexual relationships between classes (or with recent arrivals) are much more common that those within the same class.
