Even though the barcode (what I call it) shows up later in America, it shows up all over North America and not at all in South America.
That peculiarity can be explained if and only if none of the Yakuts made it to Alaska! All the rest of the Amerindian background would arrive later by boat from Philippines, Japan, China, Australia, Viet Nam, and even from Eastern Siberia.
I think the ancestors of the Yakuts were away at the time making one of their hundreds of migrations South to India (opening up a paleolithic Eastern access from what became the Silk Road).
Amazing stuff. Otzi the Iceman genome is out. Found in the border mountains of N. Italy and Austria. The closest relatives are from the Island of Sardinia.
Have you read Dale Drinnon’s recent blogs on “Migration of the Uralic Peoples”?
