**“Climate and the Peopling of the World”**

One of the most puzzling questions in modern human origins has been why the dispersal of modern *Homo sapiens* out of Africa was so delayed after their first appearance in East African fossil record near ~200 ka (ka, thousands of years ago). Fossil, archaeological, and genetic evidence indicate that early migrations into the Levant and Arabian Peninsula occurred around 120-90 ka, but the global dispersal of our kind did not occur until after 70-60 ka. New paleoclimate records and coupled climate-vegetation-population modeling constrain this narrative, highlighting the central importance of high- and low-latitude climate interactions in regulating the flows of humanity out of Africa that populated the world.
