Explanation:
The Paleolithic and Mesolithic livelihood system is known as hunting-gathering, still practiced by some peoples. The hunting-gathering was the first adaptation of humanity that was carried out successfully, occupying at least 80% of the history of mankind. The human species, from its existence 5 million years ago until ten thousand years ago, survived by hunting and gathering. Approximately thirty individuals, united by kinship, hunted ruminants and collected wild fruits and seeds. The presence of certain animals appropriated for hunting and fruits and vegetables appropriated for collection depended on the environmental characteristics of the geography in which the hunter-gatherer society was moving.
