    Interesting stuff. If we can assume that (a) 600cc is a 'small' brain
    (bigger than an average male gorilla I think), and (b) (para)humans weren't especially social, then I'd buy it.

    I can see how tribe formation might be facilitated by a challenging new environment (especially a colder one); followed by the classic feedback effect of modelling others' brains, to get to a big brain. Weren't we already dwelling in shared caves by the time we were leaving Africa though? I suppose a shared cave doesn't imply sociality... Do you have anything to suggest we might *not* have been particularly social about then? (I don't know what was in the Aiello and Dunbar paper you cited)

    Btw I liked (f)actor :)

    Cheers, Chris.
