  • 150,000-year palaeoclimate record from northern Ethiopia supports early, multiple dispersals of modern humans from Africa 

    Lamb, Henry; Bates, C. Richard; Bryant, Charlotte; Davies, Sarah; Huws, Dei; Marshall, Michael; Roberts, Helen (2018-01-18) - Journal article
    Climatic change is widely acknowledged to have played a role in the dispersal of modern humans out of Africa, but the timing is contentious. Genetic evidence links dispersal to climatic change ~60,000 years ago, despite ...
