Food sharing and cooperation are at the centre of hunter-gatherers lifestyle. No other Apes share food or cooperate to the extent that humans do. A complex network of sharing and cooperation exist within camps and between camps in different hunter-gatherer groups, regulated by social rules, friendship ties, food taboos, kinship and supernatural believes. Sharing is a crucial adaptation to hunter-gatherers lifestyle and one that is believed to be central for the evolution of mankind. Resilience project investigates the patterns of food sharing and cooperation in in different hunter-gatherer populations and how central sharing is, for hunter-gatherers resilience.
