Haplogroup I (mtDNA)
Introduction
In human genetics, Haplogroup I is a human mitochondrial DNA (mtDNA) haplogroup.
Haplogroup I is found throughout Europe, and also in Near East. It is believed to have arisen somewhere in Eurasia some 30,000 years before present, and been one of the first haplogroups to move into Europe.
Its ancestral haplogroup was Haplogroup N.
