The most-accepted hypothesis today is that evolved from and first appeared in East Africa between 2.0 and 1.8 mya. If those are not the exact species that the human line descended through during those times, our actual ancestors were close cousins. The early adults had brains of about 850 ccs, and some later specimens reached 1,100 ccs, or triple the mass of a chimpanzee’s brain. Today’s human brain only averages about 1,200 ccs (). , as with other members of the line, had a brain that was another third larger than , and probably was responsible for its relatively sophisticated material culture. But important as its growing brain was, other anatomical changes were more telling. was fully adapted for living on the ground and walking great distances. For the first quarter-million years of existence, it lived in the Oldowan culture, which used tools and weapons that were little more than rocks with sharpened edges, and probably some shaped sticks. They evolved in a highly dangerous environment and all of their ancestors slept in trees. How could they have slept on the ground? In a word: fire.

A biological assessment of what has been called the puzzle of agriculture might phrase it in simple ethological terms: why was this behaviour (agriculture) reinforced (and hence selected for) if it was not offering adaptive rewards surpassing those accruing to hunter-gathering or foraging economies?
This paradox is responsible for a profusion of models of the origin of agriculture.
