Between 2 million and 10 thousand years ago Hunter Gatherers also know as nomads did not have permanent shelters and they had to travel for food. Most of the time they where not protected from natural disasters. They had to hunt a lot of animals such as deer, bison, mammoths, and rabbits. they also collected a lot of berries for fibber.
One change the nomads discovered was the domestication of animals and being able to farm, witch was the agricultural revolution. Some of the first animals to be domesticated where sheep, chickens, cows, and horses. Nomads also started growing wheat, vegetables, and fruits to trade.
Three ways life improved after the revolution are trading, permanent housing, and developing jobs. Nomads stared settling down and became sedintary, they traded animals and different food sources. People started building permanent homes because they learned how to farm so they did not have to hunt. They started developing new jobs and work spaces. Some jobs they had were blacksmiths, stable hands, coopers, barbers, and brewers.
