The Homo Sapiens has started off in Africa. As the numbers were increasing, climate was changing, and the resources were becoming less and less, the species started to migrate out if its cradle. The migration was going from Africa to the Middle East initially, as well as in Europe through Gibraltar.
Gradually, the Homo Sapiens managed to take over the territory of the Neanderthals, and it started to spread out more and more across Eurasia. The migrations didn't stopped there though, but the humans continued through the islands of Southeast Asia and eventually reached Australia, later continuing in the Pacific Islands.
Part of the populations that lived in Eastern and central Siberia started migrated in few waves through the Bering Strait in North America, moving south and reaching Central and South America.
