... we must be wary of granting too much power to natural selection
by viewing all basic capacities of our brain as direct adaptations.
I do not doubt that natural selection acted in building our oversized
brains -- and I am equally confident that our brains became large as
an adaptation for definite roles (probably a complex set of interacting
functions).  But these assumptions do not lead to the notion, often
uncritically embraced by strict Darwinians, that all major capacities
of the brain must arise as direct products of natural selection.
