The quote is instructive to those of us trying to develop an integrated and rational view of evo psych. In my case, I DO see a lot of compelling material on how women are different from men, and I DO see a lot of compelling material on how humans are like other primates and even mammals. The quote brings me up short: do I have the sex differences within species properly "weighted" in my thinking compared to across-species similarities? Or do I switch between my microscope and my telescope paying attention only to what I am seeing, forgetting which instrument I am using to look?
