Two of South Africa’s most famous archaeological sites, Sibudu and Blombos, have revealed that Middle Stone Age groups who lived in these different areas, more than 1,000 km apart, used similar types of stone tools some 71,000 years ago, but that there were differences in the ways that these tools were made .But this was not the case at 65,000 years ago when similarities in stone tool making suggest that similar cultural traditions spread across South Africa.
