Descendant branch(s): A8a1


Haplogroup A8a is a branch on the maternal tree of humanity. Its age is not clear, but it must be younger than the birth of its parent lineage between 11,400 and 25,200 years ago (Behar et al., 2012b).

Published research on this lineage comes from two papers. The first found members in the Ket population of Siberia (Starikovskaya et al., 2005). The second found a member in the Guizhou region of China (Ji F et al., 2012).

Geno 2 data includes one person with maternal origin information. They are from Italy.

With limited but diverse information, it is difficult to determine the migration path of this lineage. It was likely part of an Asian population that migrated East to modern China and West to modern Europe.

Phylotree History

Phylotree.org is the maternal (mtDNA) tree of humanity. It is maintained by Dr. Mannis Van Oven. Each build is a major update to the tree. The current build is #17.

GenBank Samples

GenBank is a database of genetic sequence data. It is run by the United States National Institute of Health. It serves as the main repository for mtDNA full sequence profiles. Samples come both from published academic literature and donations from genetic genealogy community members. In addition to GenBank samples, listings below may include other samples published but not submitted to GenBank such as those from the HapMap project.

Note: GenBank results currently use Phylotree build 16. I am working on changing resuts over to build 17.

Geno 2.0 Data

Data from Geno 2.0 is derived from the The National Geographic Society’s Genographic Project — the DAR. The Hg ID is specific to this site and is used to protect the identities of those who take part in Genographic research. Birth Country, Mother's Birth Country, and Maternal Grandmother's Birth Country have been normalized from DAR database fields. The Maternal Origin is determined based on the three previous fields.

Note: Geno 2.0 results currently use Phylotree build 16. I am working on changing resuts over to build 17.
