Hunting hypothesis
In paleoanthropology, the hunting hypothesis is the hypothesis that human evolution was primarily influenced by the activity of hunting for relatively large and fast animals, and that the activity of hunting distinguished human ancestors from other hominins. While it is undisputed that early humans were hunters, the importance of this fact for the final steps in the emergence of the genus Homo out of earlier australopithecines, with its bipedalism and production of stone tools (from about 2.5 million years ago), and eventually also control of fire (from about 1.5 million years ago), is emphasized in the "hunting hypothesis", and de-emphasized in scenarios that stress the omnivore status of humans as their recipe for success, and social interaction, including mating behaviour as essential in the emergence of language and culture.
