Mitochondrial Haplogroup L

Mitochondrial haplogroup L

 

Macro-haplogroup L forms the deepest branches of the human mitochondrial tree – the L lineages represent the most ancient of the human lineages and are most closely linked with our shared common ancestor, often dubbed the “Mitochondrial Eve” who lived in East Africa approximately 150,000-190,000 years ago. Macro-haplogroup L is made up of haplogroups L0, L1, L2, L3, L4, L5 and L6. All of these lineages except L3 are found exclusively in Africa or in African derived populations. All non-African populations can trace their lineage back to the L3 branch which represents those who began the “Out of Africa” migration some 60-65,000 years ago. For further information regarding the distributions of the L lineages within Africa see below, which is from:
