As Marshall Sahlins shows, for most of history, humans lived in a gift economy based on abundance. And within that economy, for most food or goods people families or tribes were mainly self-reliant, drawing from an abundant nature they had mostly tamed. Naturally there were many tribes with different policies, so it is hard to completely generalize on this topic -- but certainly some did show these basic common traits of that lifestyle. Only in the last few thousand years did agriculture and bureaucracy (e.g. centered in Ancient Egypt, China, and Rome) come to dominate human affairs -- but even then it was a dominance from afar and a regulation of a small part of life and time. It is only in the last few hundred years that the paradigm has shifted to specialization and an economy based on scarcity. Even most farms 200 years ago (which was where 95% of the population lived then) were self-reliant for most of their items judged by mass or calories. But clearly humans have been adapted, for most of their recent evolution, to a life of abundance and gift giving.
