Macro-haplogroup L

In human mitochondrial genetics, L is the mitochondrial DNA macro-haplogroup that is at the root of the anatomically modern human (Homo sapiens) mtDNA phylogenetic tree. As such, it represents the most ancestral mitochondrial lineage of all currently living modern humans, also dubbed "Mitochondrial Eve".

This article is about the human mtDNA haplogroup. For the human Y-DNA haplogroup, see Haplogroup L-M20.
Haplogroup L
Time of origin230 to 150 kya
Place of originEastern Africa
DescendantsL0, L1-6

Its two sub-clades are L1-6 and L0. The split occurred during the Penultimate Glacial Period; L1-6 is estimated to have formed ca. 170 kya, and L0 ca. 150 kya. The formation of L0 is associated with the peopling of Southern Africa by populations ancestral to the Khoisan, ca. 140 kya, at the onset of the Eemian interglacial. L is further subdivided into L1-6 and L1, dated ca. 150 kya and 130 kya, respectively. Haplogroups L5 (120 kya), L2 and L6 (90 kya), L4 (80 kya) and L3 (70 kya).
