在埃及、苏丹、利比亚和乍得现在极度干旱的撒哈拉东部地区进行的150次考古发掘的放射性碳数据揭示了过去12000年来气候变化和史前占领之间的密切联系。主要时间片的天气多指标观点表明，从公元前8500年湿润条件突然出现后的初始定居过渡到自公元前5300年以来由于逐渐干旱而导致的人口外流。沙漠边缘的南移有助于引发尼罗河沿岸的法老文明的出现，影响到整个大陆的牧业传播，并影响撒哈拉以南非洲直到今天。
Radiocarbon data from 150 archaeological excavations in the now hyper-arid Eastern Sahara of Egypt, Sudan, Libya, and Chad reveal close links between climatic variations and prehistoric occupation during the past 12,000 years. Synoptic multiple-indicator views for major time slices demonstrate the transition from initial settlement after the sudden onset of humid conditions at 8500 B. C. E. to the exodus resulting from gradual desiccation since 5300 B. C. E. Southward shifting of the desert margin helped trigger the emergence of pharaonic civilization along the Nile, influenced the spread of pastoralism throughout the continent, and affects sub-Saharan Africa to the present day.
