While we started in temperate climates, about 60,000 to 80,000 years ago the first humans began straying outside of the continent in which our species was born.“This great migration brought our species to a position of world dominance that it has never relinquished,” reads a 2008 article in Smithsonian Magazine, pointing out that eventually we obviated the competition (most prominently including Neanderthals and Homo erectus).

But we’re already seeing the effects in melting glaciers and rising global temperatures.
This proved important for North America, as about 20,000 years ago, some of these people crossed over to that continent using a land bridge created by glaciation.
From there, colonies have been found in Asia dating as far back as 14,000 years ago.
