When did the first humans leave Africa?
The first modern humans began moving outside of Africa starting about 70,000-100,000 years ago. Humans are the only known species to have successfully populated, adapted to, and significantly altered a wide variety of land regions across the world, resulting in profound historical and environmental impacts.
When was the Out of Africa theory?
200,000 years ago
The “Out of Africa” hypothesis is an evolutionary theory of modern human origin that posits that modern humans arose in the late Pleistocene, about 100,000–200,000 years ago, in Africa.
What was the main reason early humans migrated from place to place?
Climate Change Some of the biggest human migrations coincided with major changes in climate, according to a new analysis. Researchers say early humans set out in search of climates where more food was available. And some populations stayed put in certain locations because barriers like glaciers blocked their progress.
Who were the first humans to leave Africa?
Who left Africa first? Homo ergaster (or African Homo erectus) may have been the first human species to leave Africa. Fossil remains show this species had expanded its range into southern Eurasia by 1.75 million years ago.

What is the out of Africa theory based on?
New research confirms the “Out Of Africa” hypothesis that all modern humans stem from a single group of Homo sapiens who emigrated from Africa 2,000 generations ago and spread throughout Eurasia over thousands of years.
How did the first humans migrate?
Around 1.8 million years ago, Homo erectus migrated out of Africa via the Levantine corridor and Horn of Africa to Eurasia. This migration has been proposed as being related to the operation of the Saharan pump, around 1.9 million years ago.
