The traditional origin story for modern humans says that early groups migrated out of Africa 60,000 years ago.
Most non-Africans can trace their origin to those migrations, but new evidence suggests that humans actually migrated out of Africa as far back as 120,000 years ago.
Those early groups may have brought tools and culture with them, and they interbred with other hominin species that existed at the time.
Tens of thousands of years ago, the first Homo sapiens — modern humans — started to cross mountains, deserts, and even oceans to leave Africa, where our species first evolved, and populate Asia and Australia.
The traditional understanding has been that this "Out of Africa" movement, as it's often referred to, happened approximately 60,000 years ago. Researchers still agree that most present day non-Africans trace the majority of their lineage to the large migration that occurred then.
