What were characteristics of early humans during the old Stone Age

The early humans that lived in the old Stone Age had much different lives than the humans in the Neolithic period or in the present. These humans were very primitive, and the most advanced they managed to get was the invention of several stone tools. The humans were still not on the top of the food chain in the old Stone Age, but instead they were hunters, gatherers, but were also hunted by the predators. These humans were nomads, and they were constantly on the move because they were not able to produce food, but instead were moving with the migration of the animals, or where there were more abundant sources of fruits, tubers, and wild vegetables.
