Little is known about the lives of early human beings. What we do know has been gathered through the study of ancient caves that scientists called archeologists believe early humans probably lived in.
The evidence suggests that the first human beings lived in caves along the southern coast of Africa. This region provided ample supplies of food as well as a warm climate.
It is believed that the men probably traveled in hunting packs or groups into the mainland looking for big game while the women stayed near the coast.
