Haplogroup N is a human mitochondrial DNA haplogroup that is primarily found in populations across Northern Europe and Asia. It is believed to have originated around 20,000 years ago, during the last Ice Age, and is associated with the migration patterns of early humans in these regions. This haplogroup is significant for studying human ancestry and population genetics, as it helps trace the lineage of certain groups. Individuals with haplogroup N may share common ancestors, providing insights into the historical movements and genetic diversity of Eurasian populations.
