Most historians agree with which theory explaining early human migration?

Humanity began in East Africa and spored to the rest of the world.

According to historians, ancestral foundation story for modern humans states that primitive groups migrated out of Africa 60,000 years ago. Maximum non-Africans can determine their origin to these migrations. However, the new evidence recommends that people actually immigrated out of Africa as far back as 120,000 years ago.

These primitive groups may have produced tools and brought culture with them, and they also interbred with other hominin varieties that survived at the time. This includes Denisovans and Neanderthals. Genetic traces of these primitive migrant groups can nevertheless be founded today.
