We are just nomads. We can't live in one place because we have to go for food and water purposes and we only live with our family's so we don't have certain things and can't make certain tools and shelters.
It takes longer to produce tools and hunting gear. (Especially when we need it.)
We have all the work done so we have more time to make our village safer.
It takes less time for us to make something because there is so many people in our community.
Communities was an important advancement we could get things done a lot earlier and this led to advancements in supplies.
This is an important advancement because we get things that we need earlier and with all the work done we could work on other things.
We helped and cared for each other more then the Paleolithic people did and that made us safer because we built trust.
