The life of early human beings was Nomadic why

Nomadic basically means to move around a lot. Many nomads raise livestock. If the livestock stay in one place too long, they will graze the plants to the point where the plants might not grow back! So it is in their own interest to move. In tropical areas, some nomads groups raise crops and practice slash and burn agriculture. People have to have water and vegetable growth to survive. Moving with weather patterns is vital for survival in order to have water and plant life. Some nomadic tribes move to avoid the very cold weather of the northern areas and find more comfort in the southern regions.
