I love the New York Times Science section. Love it. Not that I can understand a tenth of the technical articles, but the health stuff is always good, and so are the social science features. Today there’s a Q&A with a scientist who says that the reason prehistoric human beings got smart is because they started cooking their food–not because of tool making, not because of eating raw meat. Cooking. Check it out.  (If you can’t open the link, you can try searching the Times web site. The story’s entitled “From Studying Chimps, a Theory on Cooking.” The scientist is Richard Wrangham, a primatologist.)
