We used to live in small groups of people because we didn’t know how much food we would find when we moved.
We stayed in small groups but had enough people to go find food and hunt and hope they don’t get hurt or die.
With more people we were able to get bigger and more jobs done and everything was easiler to do with more people.
The first Important change is that we stayed in one place. After we started to construct permanent shelters and be able to stay in one place we started to grow bigger communities
The second major change was that with more people they were able to send people out to find things or do stuff.
When trade came along they were able to send out bigger groups and more people around the world to find things they don’t have in there area and get more and or better resources.
This is another important topic because with the creation of communites there was more people with more ideas and they could do and make many new things. Without communites we wouldn’t have big cities and we wouldn’t have friendships with others.
