Up until now, every article discussing the size of the head I read relate it to the size of the pelvis. No mention in this article. I suppose a bigger brain means a bigger head. Was the pelvis larger in those ancient humans? Was the brain/head the same size at birth then and now, meaning the brain had to grow more, and maybe ancien humans were less mature at birth?
