The reason for this post comes after the "evidence" presented by Don Matesz in his last post. I think that my answer got a little short and I think this topic is very important for understanding certain aspects of nutrition, especially when talking about evolutionary nutrition. First of all, I have to mention that humans can adapt to almost every diet. Obviously I have my own reasons for believing that a high fat diet is better than other diets, but I don't dismiss the idea that different people can get the same results using different dieting approaches.
Ok, back to the main topic. Don made the following assertion:
"Ninety-eight percent of the human genome is identical to the nearest primate relative, chimpanzees, who eat a 95 percent plant diet. Recent hunter-gatherers consume up to 20 times more meat than chimpanzees on a percent energy basis, a substantial deviation from the primate baseline."This leads us to comparative genomics. What is comparative genomics?

A very long and detailed review on human-chimpanzee comparisons has been written by Kehrer-Sawatzki and Cooper (4). I will copy some relevant excerpts for this discussion (my bolds).
