How and why did early humans migrate out of Africa?

from SAPIENS. In a study published today in Nature, researchers report that dramatic climate fluctuations created favorable environmental conditions that triggered periodic waves of human migration out of Africa every 20,000 years or so, beginning just over 100,000 years ago.

How do we know the first humans came from Africa?

Modern humans arose in Africa at least 250,000 to 300,000 years ago, fossils and DNA reveal. But scientists have been unable to pinpoint a more specific homeland because the earliest Homo sapiens fossils are found across Africa, and ancient DNA from African fossils is scarce and not old enough.
