Document Summary
Animal social behavior evolve into kinship-independent social cooperation, which is the emergency of humans: this only occurred because inexpensive coercion allowed us to be able to suppress our conflicts of interest. The strong, new selection can produce an evolutionary revolution within the past 6 million years: evolution of elite, aimed throwing, compared to the evolutionary history (6 million years), the written history (5,000 years) is merely nothing. The non-kin cooperation problem is not solved in proximal killers: benefit ccooperation < ccoercion. The non-kin cooperation problem is solved in remote killers: benefit ccooperation > ccoercion. Endocast: a mole cast made of the inside of a cranium. Stratigraphy: the outer layers of the mountains are young while the inner layers are way older. Whenever the volcanoes erupt, they release naturally decaying elements, which can be used for geographically dating. Africa now: there is little rain forest and mainly covered with savanna.
