Haplogroup: H3
mitoSearch ID: B4QTH
Mitochondrial haplogroup H is a predominantly European haplogroup that participated in a population expansion beginning approximately 20,000 years ago. Today, about 40% of all mitochondrial lineages in Europe are classified as haplogroup H. It is rather uniformly distributed throughout Europe suggesting a major role in the peopling of Europe, and descendant lineages of the original haplogroup H appear in the Near East as a result of migration. Future work will better resolve the distribution and historical characteristics of this haplogroup.
H3 is the second most common branch of H. Like H1, it is found mainly in Western Europe. However, H3 is not found in significant frequencies in the Near East. It is at its highest frequency in Iberia and Sardinia, and is about 10,000 years old.
