Answer:
The neolithic revolution
Explanation:
This was a new start to all groups. It evolved hunter and gatherers into a more "civilized" population. The people found out about agriculture. People started to farm more which lead to a good source of sustainable food. This lead people to settle down and build in the area they farmed in. More food created a more stable life which helped increase the population.
Invention of new weapons/gases was HUGE, but Disease and famine was also a large factor
