Enlighten me then with your wisdom. Where did this increased brain size and capacity come from then? Increased brain capacity that had nothing to do with any change in behaviour and nothing to do with any revolutionary change in child rearing back in the Paleolithic. No change in gender roles and nothing to do with play, myth or ritual? You are not making any sense or rational debate. So we are following the Flintstones family model of child rearing now then I guess?
If it had nothing to do with a revolution in child rearing, then why didn't chimps grow bigger brains? All the same reasoning you give would apply equally to chimps, and they should have grown bigger brains in competition with humans. Why didn't they?
