Data on 120,000 nurses suggest that protein from poultry and dairy foods--but not from red meat--may reduce by one-third the risk of dying of cancer. Cutting down on fat, however, doesn't seem to make a bit of difference...

Whoever did it, the creation of technology gave its inventors an astonishing advantage over other hominid species. Stone hammers and blades let them exploit carcasses left behind by other predators and permitted them to shift to an energy-rich, high-fat diet. "That," asserts Asfaw, "leads to all kinds of evolutionary consequences...
