Is this new? I thought this was already known?

What about Americans?

I can`t see anything there saying they checked American DNA. Only people from Eurafrasia + Australia. Seems a bit presumptous to suggest people everywhere came from Africa at the same time without even checking a fairly large part of the world. Not 100% sure but I don`t expect 80k years is enough time for the Americas to have drifted away from Eurafrasia. Which also raises another question, even if Americans too came from Africa at the same time then how did they actually get to the Americas?

America was connected with Asia via Alaska.

It's not a new theory but I think there was still some debate about whether or not it was multiple waves of exodus from out of Africa or centrally basically one group. 

Looks like basically it was one group. I guess they hit the equivalent of the genetic lottery because their genes have spread and spread while everyone's elses either got stuck in Africa or died out. 

Guess you can walk a lot when you don't have TV, or internet, or anything to do and just need food, lol.
