Bones found in South Africa help support the theory that modern humans originated in Africa.

Fossilised bones from hominids (part of the human evolutionary chain) dating back between 4.5 and 2.5 million years were found in limestone caves some 50km northwest of Johannesburg. In the Sterkfontein Caves, now part of what is known as the ‘Cradle of Humankind’, there was also evidence that humans used stone tools two million years ago and made fire 1.8 million years ago.
