Lotta subjunctives here. Not to be Popperian or anything, but isn't there something unsatisfactory about a way of thinking that requires hypothesis piled upon hypothesis, and offers no way to confirm or refute any of them?
It would be easy enough to come up with any number of such explanations for the perverse placement of the clitoris, or any other vexatious trait. A quick troll through Google suggests that one popular, competing sociobiological explanation for the shy little pearl's out-of-the-way domicile is that it encourages women to select sexual partners with large penes. I do not have the privilege of possessing a clitoris myself, but perhaps some of our clitoridiferous fellow-listers can comment on whether well-endowed partners do or do not create more clitoral bliss, just as a physical side-effect of megalophally.
A cynical reader might speculate that Andie thinks nature selects for Alan Alda because of an ideological commitment to Aldatude; other sociobiological tale-spinners may have ideological commitments that lead them to emphasize hammer-tude. How to decide?
