Humans went threw a huge revolution it was about 11,000 years ago and a revolution is a wide spread change of life. Then as we were getting smarter and smarter they started to settle down and start communities and began farming.This was called the Neolithic Revolution, but this did not happen quickly because it was several thousand years. So as people were building communities some other's were still moving around the world to make a new community or they were just hunting for food for themselves and finding a good place to live were no one was and those people were called nomadic and how they were moving that was called migrating that word means moving to place to another place. As people were settling down to a place they were running out of food so some people went hunting but it was only men who hunted for food and the women were farming. The place that they settled down was in the fertile crescent because the soil there was fertile to grow plants and in the fertile crescent had protection for the people who lived there because the mountains, ocean, and desert were protecting them from danger. When the people settled down it was about 31,000 years ago when they started.
