A map of the world, showing the routes that humans took as they spread out from Africa. There is still debate on a lot of this, on the timelines and the routes (less so on the latter, but how early humans came to North America has been pushed back a few times in recent years in the light of archeological evidence). The map shows us originating in Africa, then with thick red lines and arrows, the routes we took as we spread out across the globe: Origin in Africa: 150 000 - 100 000 years ago (my note: Homo Sapiens is thought to have originated around 200 000 years ago, so maybe they stuck around for a while before migrating? Perhaps we just haven't found evidence of earlier, failed migrations) Middle East: 100 000 - 90 000 years ago India: 60 000 years ago China and SE Asia: 60 000 - 50 000 years ago Australia: 50 000 - 40 000 years ago Europe: 40 000 years ago Siberia: 35 000 - 25 000 years ago Land bridge to North America: 15 000 years ago Mexico: 14 000 years ago Eastern North America: 12 000 years ago South America, down to the sourthernmost tip at Tierra del Fuego: 11 000 years ago Islands in the South Pacific Ocean and beyond to Hawaii and Rapa Nui: 3000 - 1000 years ago.

@fzimper @zleap @petergleick The timelines change a bit, as new evidence comes to light, but I think the *routes* are generally agreed on. North America was populated between 10 000 and 20 000 years ago by folks coming across a land bridge from Asia. And, go back far enough, we originate in Africa.
