During Paleolithic times people had to live in caves our rough like structures. Although these homes didn't last long the tribe had to move with the animals for food. They also moved to find better or more water.
During Neolithic Times people built more sturdy and stable houses to live in for a longer period of time. While the houses where sturdy they also had a good interior with many bedrooms and shelves to store food, water canteens, and resources. They also farmed food like cattle/ cows, pigs, and wheat, so they didn't have to move.
The impact this had on humankind is, that we got smarter and we had more advanced tools. Also, we traded/gifted to help out any other tribes or give them thankings/honors.
