Neolithic Revolution (~12,000 BC)

The Neolithic (New Stone) Revolution occurred about 10,000 years ago and dramatically changed the way that early humans lived. Two important factors come out of the Neolithic Revolution:

1:The development of agriculture and
2:The domestication of animals.
These two changes allowed people to stay in one spot instead of wandering from place to place following their main food source (animals).

Now people were put in the situation of living together permanently and as a result much cooperation was needed for survival and civilizations started to arise.
