I know that I should probably be doing October of 2014, since I’m sort of working my way outward from January of 2015.

The Evolution of Diet talks about the “Paleo diet,” which posits that people should be eating a meat-based diet that limits, or eliminates, beans, grains, and dairy products. The theory is that the human genome hasn’t evolved in the last ten thousand or so years. It starts out speaking kind of positively about the Paleo diet, arguing that the hunter-gatherers’ inclusion of meat in the diet is part of what allowed us to develop advanced brains. However, as the article progresses, we get farther from this argument. Gibbons quotes Amanda Henry, who has found evidence that humans have been eating grains and tubers for at least the last hundred thousand years. Gibbons also quotes Sarah Tishkoff, who makes the point that humans did not stop evolving ten thousand years ago. We are still evolving and many populations have evolved to digest lactose and starches that others have not.
