Matt: There is only one necessary preadaptation for eusocial behavior: nesting. For bees and wasps, its obvious, but for humans, it was the creation of fire. Even nomads stop and build a nightly "nest" based around fire.

> The combination of nesting behavior coupled with the necessary labor division coupled with the ability to quite literally walk into completely new environments created an evolutionary whirlwind. This is backed up by the way, by the fact that genetic diversity on the motherland of Africa is higher than it is everywhere else.-You make an excellent point. Robert Wright's books on evolutionary psychology of earlier humans makes the same points.
