Harvard's Daniel Lieberman argues that genus Homo differs from other early hominins through an integrated suite of behaviors, collectively termed hunting and gathering, that emerged sometime between 3 and 2 mya. The emergent properties associated with hunting and gathering made possible increased access to energy. More energy, in turn, led to further selection for increased brain size, larger body size, and slower life histories, characteristics which are all associated with the genus Homo.
