Welcome to European Tribune. It's gone a bit quiet around here these days, but it's still going.
Westerfeld effect - the incest avoidance mechanism in our brains works by remembering who we spent our childhoods with and killing all sexual interest in that set of people. It probably works by remembering pheromone complexes. (for obvious reasons.. not a lot of research into how this works, exactly)
 This has a bunch of knock on effects -most notably, almost all incest that does not involve damaged people happens because the kids were raised apart. More commonly, unrelated kids raised together from infancy do not usually knock boots, ever. It is probably also why small tribes almost always practice(d) exogamy or strictly segregated child rearing. Those tribes that did not do at least one of them failed to reproduce.
