Abstract:
Archaeological findings, numerical human dispersal models and genome analyses suggest several time<br/> windows in the past 200 kyr (thousands of years ago) when anatomically modern humans (AMH)<br/> dispersed out of Africa into the Levant and/or Arabia. From close to the key hominin site of Omo-Kibish,<br/> we provide near continuous proxy evidence for environmental changes in lake sediment cores from the<br/> Chew Bahir basin, south Ethiopia. The data show highly variable hydroclimate conditions from 116 to 66<br/> kyr BP with rapid shifts from very wet to extreme aridity. The wet phases coincide with the timing of the<br/> North African Humid Periods during MIS5, as defined by Nile discharge records from the eastern<br/> Mediterranean. The subsequent record at Chew Bahir suggests stable regional hydrological setting between<br/> 58 and 32 kyr (MIS4 and 3), which facilitated the development of more habitable ecosystems,<br/> albeit in generally dry climatic conditions. This shift, from more to less variable hydroclimate, may help<br/> account for the timing of later dispersal events of AMH out of Africa.
