Most primates have the capacity for eating sugary fruit, the capacity for eating leaves and the capacity for eating meat. But meat is a rare treat, if eaten at all. Sure, chimpanzees sometimes kill and devour a baby monkey, but the proportion of the diet of the average chimpanzee composed of meat is small. And chimps eat more mammal meat than any of the other apes or any of the monkeys. The majority of the food consumed by primates today–and every indication is for the last thirty million years–is vegetable, not animal. Plants are what our apey and even earlier ancestors ate; they were our paleo diet for most of the last thirty million years during which our bodies, and our guts in particular, were evolving. In other words, there is very little evidence that our guts are terribly special and the job of a generalist primate gut is primarily to eat pieces of plants. We have special immune systems, special brains, even special hands, but our guts are ordinary and for tens of millions of years those ordinary guts have tended to be filled with fruit, leaves, and the occasional delicacy of a raw hummingbird.Human Ancestors Were Nearly All Vegetarians

Compulsory schooling has been a fixture of our culture now for several generations. It’s hard today for most people to even imagine how children would learn what they must for success in our culture without it. President Obama and Secretary of Education Arne Duncan are so enamored with schooling that they want even longer school days and school years. Most people assume that the basic design of schools, as we know them today, emerged from scientific evidence about how children learn best. But, in fact, nothing could be further from the truth.School is a prison
Schools as we know them today are a product of history, not of research into how children learn. The blueprint still used for today’s schools was developed during the Protestant Reformation, when schools were created to teach children to read the Bible, to believe scripture without questioning it, and to obey authority figures without questioning them. The early founders of schools were quite clear about this in their writings. The idea that schools might be places for nurturing critical thought, creativity, self-initiative or ability to learn on one’s own — the kinds of skills most needed for success in today’s economy — was the furthest thing from their minds. To them, willfulness was sinfulness, to be drilled or beaten out of children, not encouraged.
