WORLD HISTORY

Detailed explanation-1: -Between 70, 000 and 100, 000 years ago, Homo sapiens began migrating from the African continent and populating parts of Europe and Asia. They reached the Australian continent in canoes sometime between 35, 000 and 65, 000 years ago.

Detailed explanation-2: -Though it is unclear when some modern humans first left Africa, evidence shows that these modern humans did not leave Africa until between 60, 000 and 90, 000 years ago. Most likely, a change in climate helped to push them out.

Detailed explanation-3: -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.
