Sorry, but I’m actually not too knowledgeable on the subject. I happened to have heard of those two evolutionary trends, and since your original post wasn’t too specific, I thought you might be interested.
You could try consulting some resources on evolutionary psychology. Though I haven’t read it (yet—the copy is sitting on my bookshelf), I’ve heard good things about The Moral Animal.
