In human mitochondrial genetics, Haplogroup L3 is a human mitochondrial DNA (mtDNA) haplogroup. Haplogroup L3 has played a pivotal role in the history of the human species. Soon after the haplogroup arose in East Africa a relatively small number of migrants carried it across the Red Sea to Arabia, inaugurating an intercontinental migration that eventually settled every major land mass on Earth except Antarctica. That small group also gave rise to every non-African haplogroup.[4]

Origin

L3 is believed to have arisen in Eastern Africa between 84,000 to 104,000 years ago.[1]

Distribution

It is most common in East Africa, in contrast to others parts of Africa where the haplogroups L1 and L2 represent two thirds of mtDNAs.[5]

L3 is sub-divided into several clades, two of which spawned the macro-haplogroups M and N from which the vast majority of non-Africans are descended.

One of these lineages, defined by loss of the DdeI site at np 10394, represents only a few percent of the African mtDNAs but appears to be the progenitor of roughly half of all European, Asian and Native American mtDNAs."[6]

According to Maca-Meyer et al. (2001), "L3 is more related to Eurasian haplogroups than to the most divergent African clusters L1 and L2".[7] L3 is the haplogroup from which all modern humans outside of Africa derive.[8]

Tree

This phylogenetic tree of haplogroup L3 subclades is based on the paper by Mannis van Oven and Manfred Kayser Updated comprehensive phylogenetic tree of global human mitochondrial DNA variation[3] and subsequent published research.
