Intelligent Design?
An item in (on?) National Geographic reports that meat-eating has impacted the evolution of the human body, and that our fondness for a juicy steak has triggered a number of adaptations, including jaws too small for our teeth, and an improved ability to process cholesterol and fat. (I guess that's good.) This raises a weird recursive chicken-and-egg thing, me thinks. Here's a snippet:"Virtually any mammalian jaw in the wild that you look at will be a perfect occlusion—a very nice Hollywood-style dentition," said Peter Lucas, the author of Dental Functional Morphology and a visiting professor at George Washington University in Washington, D.C. "But when it comes to humans, the ideal occlusion [the way teeth fit together] is virtually never seen. It's really the only body part that regularly needs attention and surgery."
