Dear Wikiwand AI, let's keep it short by simply answering these key questions:
Can you list the top facts and stats about Haplogroup N (mtDNA)?
Summarize this article for a 10 year old
Haplogroup N is a human mitochondrial DNA (mtDNA) clade. A macrohaplogroup, its descendant lineages are distributed across many continents. Like its sibling macrohaplogroup M, macrohaplogroup N is a descendant of the haplogroup L3.
Haplogroup N | |
---|---|
Possible time of origin | ~55-70,000 YBP[1][2] or 50-65,000 YBP[3] |
Possible place of origin | Asia[4][5][6][7][8] or East Africa[9][10][11] |
Ancestor | L3 |
Descendants | N1'5, N2, N8, N9, N10, N11, N13, N14, N21, N22, A, I, O, R, S, X, Y, W |
Defining mutations | 8701, 9540, 10398, 10873, 15301[12] |
All mtDNA haplogroups found outside of Africa are descendants of either haplogroup N or its sibling haplogroup M. M and N are the signature maternal haplogroups that define the theory of the recent African origin of modern humans and subsequent early human migrations around the world. The global distribution of haplogroups N and M indicates that there was likely at least one major prehistoric migration of humans out of Africa, with both N and M later evolving outside the continent.[7]
