2. The oldest mathematical artifact, the Lebombo bone, dates back to more than 35,000 years ago. It was found in the Lebombo Mountains near Swaziland.
3. Digital computer systems originated from ancient African cultural practices.
4. Many African cattle and sheep hearders recognize their herd through facial and pattern recognition.
5. The development of geometrical thinking started in early African history as hunter-gatherers of the Kalahari Desert in southern Africa learned to track animals by getting to know the shape of their poop to learn which animal passed by, how long ago, if it was hungry or not, etc.
6. Cowrie shells were a popular form of currency across Africa.
7. Geometry and symmetry in repeated patterns can be seen throughout the area south of the Sahara, in forms of artistic designs on houses, gourd, baskets, pipes, and other everyday items.
