Granted, but that particular claim is not especially relevant to this conversation, nor does Wikipedia's article on Kanazawa refute Jokela's findings. My purpose for linking to that wasn't to highlight the "women are getting more more beautiful" headline but simply to draw a connection from the claim that beautiful women reproduce more to the conclusion that obese women would therefore reproduce less. I don't back this claim, because I haven't read the paper, but unverified data is better than no data.
