The invention of mathematics is placed firmly in African prehistory. The oldest known possible mathematical object is the Lebombo bone, which was discovered in the Lebombo Mountains of Swaziland and dated to approximately 35,000 B.C. Many of the math concepts that are learned in school today were also developed in Africa. Over 35,000 years ago, Ancient Egyptians scripted textbooks about math that included division and multiplication of fractions and geometric formulas to calculate the area and volume of shapes.
Many treatments used today in modern medicine were first employed in Africa centuries ago. The earliest known surgery was performed in Egypt around 2750 B.C. Medical procedures performed in ancient Africa before they were performed in Europe include vaccination, autopsy, limb traction and broken bone setting, bullet removal, brain surgery, skin grafting, filling of dental cavities, installation of false teeth, what is now known as Caesarean sections, anesthesia and tissue cauterization.
