DS, I have discovered that the biologist PZ Myers is also skeptical of evolutionary psychology: http://freethoughtblogs.com/pharyngula/category/bad-science/evolutionary-psychology/ so I am not yet convinced that I have to accept evolutionary biology and evolutionary psychology as a package deal, though of course I recognise that our brains were subject to evolutionary processes as well.
Cofty, thanks for your response, I was hoping you would contribute to this thread, I will try to come back with some examples for you tomorrow.
