Though it is typically used to refer to a family of lineages found in AFRICA, L1 is sometimes referred to as haplogroup L1-6, which is the macrohaplogroup that includes the majority of African lineages and all non-African lineages. Haplogroup L1-6 is the macrohaplogroup that includes subclades L1, L2, L4, L5, L6, and also L3 which gave rise to the two non-African haplogroups M and N. Haplogroup L1-6 and its only sibling haplogroup L0 are united by the matrilineal most recent common ancestor, (MRCA) of all living humans, Mitochondrial Eve. The existence of these two lineages, implies that Mitochondrial Eve had at least two daughters, one of whom is the maternal common ancestor of haplogroup L1-6 lineages.
