Oldest Footprint Study Could Rewrite Human History.
A 153,000-year-old footprint has been discovered in South Africa, proving that humans were walking around 30,000 years earlier than previously thought. The discovery was made using the optically-stimulated luminescence dating method, which analyses how long it’s been since a grain of sand has been exposed to sunlight. The scientists involved believe that the area could be home to many illuminating discoveries given the makeup of the soil and that further hominin ichnosites are waiting to be discovered on the Cape South Coast and elsewhere on the coast.
