Here is an interesting read on the genetic makeup of humans. The most interesting point is that all of 10,000 years ago, we developed agriculture, which caused humans to become more sedentary, changing from hunters to farmers, contrary to how previous humans had lived for hundreds of thousands of years, which the article contends is the main cause of many of our problems today. I would further add to the argument that the last 200 years has brought much the same level of change as we converted from an agricultural society to an industrial one. Comparing my day and that of out ancient ancestors, one would think you were talking about two different animals. An interesting read on a rainy day stuck in the office.
