Haplogroup O is a branch on the maternal tree of human kind. It is a child of haplogroup N. It was likely born in the Southeast Asia around 52,000 years ago. (Behar et al., 2012b)


Most researchers consider the birthplace of E to have been born in Southeast Asia.


Behar et al., 2012b placed the birth of the O lineage between 45,700 and 58,400 years ago. This means the line was born in the Upper Paleolithic. At the time, people were using stone tools.

National Geographic Geno 2.0 Text

Haplogroup: O
Age: About 51,000 Years Ago
Origin: Southeast Asia
Blurb: This branch in your maternal ancestors’ journey marks the point where groups traveled to Sahul, the landmass that once connected New Guinea and Australia. Your ancestors journeyed along the coastlines of Southeast Asia to reach Sahul. When the Paleolithic period ended and climate change led to higher sea levels, the land connecting what are now islands became submerged.Today, geneticists have found this lineage exclusively in modern native Australian populations.

mtDNA Haplogroup O 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.

mtDNA Haplogroup O 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 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.
