Answer 2

To answer in one word : Interdependence

That's how early men used to live. No business, no money they just hunted, gathered ate, had sex, slept, died.

Then slowly they began inventing things. This lead to development of some skills.

Example :- I would be good in gathering, my clan mate good with hunting, another clan mate good with medicine. Other clan mate would heal us when we had issues.

When this became macro level it was called BARTER SYSTEM.
