I like this life much better than when we used to live in a cave .
They are spending to much time much time away from their family for hunting. Thats when the idea hit them , instead of killing the animal we can capture them and bring them home to make them fat so that they will get more food. The berries we can grow for our food so they wont have to go out and collect them every day.
They figured out that they can domesticate the wild animals so that they don't have to go and leave their family.Instead they garden and teach their kids how to and stop risking many children's life.they are now able to make their food fat and can grow their own produce. Now they don't have to go out collect berries or hunt.
Now they've learned that being in a community can be helpful because they can now trade and some can be farmers while others can be blacksmiths because they can trade when their done. They can also work together to do things such as hunt (if needed) or learn how to farm. Another thing that comes in handy when living in a community is that you have others to help you when you are struggling with something
