The domestication of different grasses, all members of the monocotyledonous family Gramineae, was a seminal event in the history of mankind. The cultiva￾tion of these plants led to the generation of agricultural surpluses. These in turn enabled societies in different parts of the world to make the transition from a nomadic or semi-nomadic lifestyle to one based on communities living in per￾manent settlements
