Overview

Q-Z782 is a parallel branch to Z781 under Q-Z780 and reflects early diversification towards northern and eastern ecological zones of North America. The clade is associated with populations living along the northern forest, coastal, and subarctic interfaces, where early post-glacial migration corridors fostered distinct paternal structures.

Geographic distribution

Moderate frequencies among northern Algonquian groups, some coastal northeastern Native American populations, and subarctic communities. Occasionally appears among Inuit-admixed populations due to regional interactions.

Ancient DNA

  • Genetic signatures consistent with Z782 appear in early Holocene samples linked to northern coastal cultural complexes.
  • The age correlates with expansion along post-glacial ecological corridors in the northeastern subarctic zone.
  • Z782 may represent one of the earliest parallel radiations alongside Z781 in the northern continent.

Phylogeny & subclades

Sits directly under Z780 as a sister branch to Z781. Contains small clusters tied to northeastern and subarctic regions.

  • Q-Z782*

Notes & context

Z782 adds resolution for distinguishing coastal–northern paternal histories from interior expansions.
