Nicholas: Welcome to EvCForum!
An excellent paper and well-reasoned argument. Much appreciated.
One question: besides brain structure (which you addressed admirably in that paper), are there other features of
H. sapiens that might be considered neotenic? I have heard that the relative hairlessness of human adults is also a neotenic feature. (I've also heard that hairlessness relates to an adaptation for savannah dwelling, i.e., heat exchange). Since this isn't my area, I'd appreciate your thoughts on the subject.
