At the bottom of the food chain we find food sources that should form the foundation of human nutrition. In the history of man there are two nutritional epochs: pre-agricultural and post-agricultural. Our species ceased evolving at about the same time as the post-agricultural epoch began. Coincidence or not, the human animal has not evolved one iota since the beginning of the post-agricultural era. Since that genetic high-water point, we have begun a slow descent that has gathered incredible momentum since around 1950, when industrial chemical production and use peaked dramatically. The true superman existed 10,000 years ago, in the pre-agricultural era. We should try to learn what kinds of foods nourished this super ancestor of ours.
