Haplogroup L is a human mitochondrial DNA haplogroup primarily found in South Asia, particularly in regions like India and Pakistan. It is believed to have originated around 20,000 years ago and is associated with the early populations of the Indian subcontinent. This haplogroup is significant for studying human migration and ancestry in this area. Haplogroup L is divided into several subclades, each representing different lineages. Genetic studies of haplogroup L help researchers understand the genetic diversity and historical movements of populations in South Asia. It also provides insights into the relationships between various ethnic groups within the region.
