Haplogroup L3
Videos
Haplogroup L3 is a human mitochondrial DNA haplogroup. The clade has played a pivotal role in the early dispersal of anatomically modern humans.
Proposed migration route depicting the origin of L3 in Africa and its dispersal both out of and within the continent, with two possible models (as depicted by Vai et al.) (a) Haplogroup N differentiates from L3 in Africa, with a subsequent spread out of Africa, and differentiation of haplogroup M from L3 outside Africa. (b) Haplogroups M and N diverge from L3 outside Africa after the expansion of L3 from the continent; later migrations during the Upper Paleolithic and Neolithic led some lineages back to North Africa. (Haplogroups are indicated in black circles in their probable area of origin.)
Proposed migration route according to the Asian origin hypothesis (Cabrera et al.). a: Exit of the L3 precursor to Eurasia. b: Return to Africa and expansion to Asia of basal L3 lineages with subsequent differentiation in both continents.
Haplogroup M (mtDNA)

Haplogroup M is a human mitochondrial DNA haplogroup. An enormous haplogroup spanning all the continents, the macro-haplogroup M, like its sibling the macro-haplogroup N, is a descendant of the haplog
Haplogroup L3
…possibility of an origin of L3 in Asia was proposed by Cabrera et al. (2018) based on the similar coalescence dates of L3 and its Eurasian-distributed M and N derivative clades (c. 70 kya), the distant location in Southeast Asia of the oldest known subclades of M and N, and the comparable age of the…
