In the Paleolithic Era, we were always on the move and never had permanent shelters. We made small temporary homes because we were Nomads. We kept on following animals and herds to soon hunt them.
It was important for us to develop permanent shelters, so we stay in one place and not have to move around as much. When we built bigger and better house it saved us from harsh weather.
Our second important change was that we stored and cooked food in our homes. We dug holes in the dirt in dark places, because dark places are good for storing food. The dark places are cool in temperature. We also dug a hole in the dirt to make fires to cook.
This topic is important because permanent homes protected us from the harsh weather. This new way of life helped us stay in one spot all the time. Also, it help us develop how we cook and store our food.
