Further information: Hunting hypothesis
Hunting has a long history and may well pre-date the rise of species Homo sapiens. While our earliest Hominid ancestors were probably frugivore or omnivore, there is evidence that early Homo, and possibly already Australopithecine species have used larger animals for subsistence, and that hunting may have been one of the multiple environmental factors leading to replacement of holocene megafauna by smaller herbivores.
Of the closest surviving relatives of the human species, Pan, the Common Chimpanzee has an omnivorous diet including troop hunting behavior based on beta males led by an alpha male, while the less violent Bonobos, have a mostly frugivorous diet.
While it is undisputed that early humans were hunters, the importance of this fact for the final steps in the emergence of the Homo genus out of earlier Australopithecines, with its bipedalism and production of stone tools, and eventually also control of fire, are 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 behavioral modernity.
With the establishment of language, culture and religion, hunting became a theme of stories and myths, besides rituals such as dance and animal sacrifice. Hunting was a crucial component of hunter-gatherer societies before the domestication of livestock and the dawn of agriculture, beginning about 11,000 years ago. By the Mesolithic, hunting strategies had diversified with the developent of the bow (by 18,000 years ago) and the domestication of the dog (about 15,000 years ago).
There is fossil evidence for spear use in Asian hunting dating from approximately 16,200 years ago. The North American megafauna extinction was coincidental with the Younger Dryas impact event, making hunting a less critical factor in prehistoric species loss than had been previously thought.Many species of animals have been hunted and caribou/wild reindeer "may well be the species of single greatest importance in the entire anthropological literature on hunting" (see also Reindeer Age).Hunter-gathering lifestyles remained prevalent in the New World and Sub-Saharan Africa (with the notable exception of Aztec and Incan agriculture) until the European Age of Discovery, and they persist in some tribal societies, albeit in rapid decline. Peoples that preserved paleolithic hunting-gathering until the recent past include some indigenous peoples of the Amazonas (Aché), some Central and Southern African Bushmen (Hadza people, Khoisan), some peoples of New Guinea (Fayu), the Mlabri of Thailand and Laos, the Vedda people of Sri Lanka and a handful of uncontacted peoples.
