The Lebombo Bone, the oldest mathematical science tool (found in Border Cave in the Lebombo Mountains between South Africa and Swaziland).
Too often do Western history books attribute mathematics to a European origin, which is simply not true. Many peoples around the world have contributed to mathematical sciences, however, chronologically, its origins are rooted in Africa.
In the 1970’s during the excavations of Border Cave, a small piece of the fibula of a baboon, the Lebombo bone, was found marked with 29 clearly defined notches, and, at 37,000 years old, it ranks as the oldest mathematical objects known. It resembles the calendar sticks still in use by Bushmen clans in Namibia today.
This bone bears witness to the existence of a very sophisticated accounting system [in Africa] which enabled man to master time (lunar phases, etc.). It is the first visible hint of the emergence of calculation in human history
