Quote:False. The caring of those with a broken bone is probably reflective of heritable behavioral trait which enhances the social support network of the bearer of the trait, which confers a survival advantage upon the bearer. This is Darwinian evolution red in tooth and claw, as evidenced by most human societies now having hospitals.
I disagree. For a small HG band - the care of an unproductive mouth would have been a serious drain on resources.
