Pottery Neolithic Sang-i Chakmak. The process was not as linear as was once thought, but a more complicated effort, which was undertaken by different human populations in different regions in many different ways. Most of the other achievements of humankind have followed from this one. Hence we may ask, do these findings mean that cereals and milk are chemically rewarding?

If wild cereals were in fact a minor part of the diet, any argument based on caloric need is weakened. State University of New York Press. The ingestion of cereals and milk, in normal modern dietary amounts by normal humans, activates reward centres in the brain. This makes the case for chemical reward as the motive for agriculture much stronger. Groups which practised vegeculture of fruits, tubers etc.

For the social philosophy, see agrarianism. But would susceptibility to the rewarding effects of exorphins lead to lower, or higher, reproductive success?
