Haplogroup L1 is a human mitochondrial DNA (mtDNA) haplogroup. It is most common in Central Africa and West Africa.
It diverged from L1-6 at about 140,000 years ago (140.6+33.7
−33.0 kya 95% CI).[3]
Its emergence is associated with the early peopling of Africa by anatomically modern humans during the Eemian, and it is now mostly found in Central African foragers.
