 That, for me, was a pretty good validation of the hunter-farmer theory. Then I met cultural anthropologist Jay Fikes, Ph.D., who wrote the famous books debunking Carlos Castaneda. Dr. Fikes obtains his Ph.D. by studying the few remaining Native American hunting societies of the American Southwest and northern Mexico. After reading my book, he wrote a ringing endorsement of it, saying that his experience taught him that hunting and agricultural societies were profoundly different.
