“We are still evolving. Right now, however, the most potent form of evolution is not biological evolution of the sort described by Darwin, but cultural evolution, in which we develop and pass new ideas and behaviors to our children, friends and others. Some of these novel behaviors, especially the foods we eat and the activities we do (or don't do), make us sick.” — Daniel E. Lieberman
