Haplogroup N (M231) is a Y-chromosome DNA haplogroup typical of Northern Eurasia, which is defined by the presence of the marker M231
Origins
Haplogroup N-M231 is a descendant haplogroup of Haplogroup NO1-M214. Its most recent common ancestor with its nearest outgroup, haplogroup O-M175, is estimated to have lived about 36,800 or 41,900 years ago. However, extant haplogroup N-M231 is considered to be 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.
It is suggested that N-M231 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 (Rootsi 2006).
The absence of haplogroup N-M231 in the Americas indicates that its spread across Asia happened after the submergence of Beringia (Chiaroni 2009).
Possible time of origin 36,800 [95% CI 34,300–39,300] years before present
41,900 [95% CI 31,294–51,202] years ago
Possible place of origin East Asia
Coalescence age 22,100 [95% CI 19,800–24,400]
19,153 [95% CI 13,677–24,422] years ago
about 21,000 years ago
