GENERAL KNOWLEDGE

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: -Most scientists subscribe to the view that Homo sapiens arrived in North America less than 20, 000 years ago. The latest study raises the possibility that another hominin species, such as Neanderthals or a group known as Denisovans, somehow made it from Asia to North America before that and flourished.

Detailed explanation-3: -The oldest human fossil remains found in Australia date to around 40, 000 years ago – 20, 000 years after the earliest archaeological evidence of human occupation. Nothing is known about the physical appearance of the first humans that entered the continent about 50, 000 years ago.

Detailed explanation-4: -For a long time, the accepted account had been that, after anatomically modern humans dispersed from Africa into Europe and Asia, groups of hunters entered North America from Siberia at the end of the last ice age around 13, 500 years ago, using a land bridge across the Bering Strait.
