Short summary
During the past 260 000 years, rains over southern South Africa underwent many fluctuations which could have affected the behaviour and innovations of humans living there. In this study we reconstruct the rainfall during this period in this area using X-ray analysis of a sediment core retrieved in the ocean south of South Africa. We confirmed that a 23 000-year cycle of the orbit of the Earth affected rainfall and that rainfall was higher around 117 000, 93 000 and 72 000 years ago.
