Haplogroup A1a is a Eurasian branch on the maternal tree of humanity. It is between 3,700 and 10,800 years old (Behar et al 2012b).

Published research includes highly diverse origins for this lineage. The earliest study including the lineage has a sample from Japan (Tanaka et al., 2004). From Derenko et al., 2007 comes a sample from Velikij Novgorod in Russia while Derenko et al., 2013 includes a sample from Iran. A shared additional mutation shared by these two samples indicates a connection. Meanwhile, a citizen science donation comes from an ethnic Turk in Turkey (Greenspan et al., 2006 – 2016).

Geno 2 data includes additional origins including Germany, India, Japan, the United Kingdom and many participants in the United States with European origins.

It is not clear if the diverse origins stem from migrations both east and west from Central Asia or are part of a complex Western migration from East Asia.

It is worth noting that prior to Phylotree build 16 it was known as A4a1 in published research.

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.

mtDNA Haplogroup A1a Data Sources

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 results over to build 17.
