Villages Develop
With the advent of farming and domesticated animals to feed a society, life became much easier for early humans. As a result, many more humans survived the difficulties of life. The population quickly rose from around 2 million humans on the Earth, to more than 90 million.
Farming allowed people to build villages along rivers, or wherever the ground was fertile enough for crops to grow. Archeologists have found some villages that are believed to have been built more than 8,000 years ago. Some of these ancient villages, such as Jericho, still survive to this day.
