“The expansion of Homo sapiens across Eurasia marked a major milestone in human evolution that would eventually lead to our species being found across every continent,” write the authors of new research published today in Science Advances.

But scientists still aren’t sure how early modern humans managed to pull off this remarkable migrational trick, given considerable environmental variations around the world. The new study, co-authored by Sarah Pederzani from the Max-Planck-Institute for Evolutionary Anthropology, sought to explore the climatic conditions experienced by Homo sapiens when venturing from southwest Asia to Europe.
