What led ancient people to a sedentary lifestyle?

The ancient people came to settled life as the technology of metal processing developed. The metal tools made it possible to cultivate the land over a large area, and thus it became possible to obtain enough food from one place. And this meant that people no longer had to wander from one place to another and engage in gathering. After agriculture, people began to domesticate wild farm animals, thanks to which primitive people could do without hunting as well.
