Haplogroup N-M231
Haplogroup N (M231) is a Y-chromosome DNA haplogroup typical of northern Eurasia, defined by the presence of the marker M231.〔
==Origins==
Haplogroup N-M231 is a descendant haplogroup of Haplogroup NO. It is considered relatively young, having populated the north of Eurasia after the last Ice Age. Males carrying the marker apparently moved northwards as the climate warmed in the Holocene.
The absence of haplogroup N-M231 in the Americas indicates that its spread across Asia happened after the submergence of the Bering land bridge . It is suggested that it arose in southeast Asia 19.4±4.8 ky years ago, and then migrated in a counter-clockwise path from modern day regions of Mongolia and northern China to as far as northeastern Europe .
