About us

As of April 2018, I no able to view the project members test results. I assume this is due to an incompatibility in the FTDNA web page and my web browser.  In any case, this seems like a good time to resign as a project administrator and hand over the project to another person.   If you are interested in volunteering as a project administrator, please email one of the remaining project admins, or if they do not respond, please contact FTDNA.
Best regards,

mtDNA haplogroup L0

Each person's mtDNA is inherited solely from their mother, and therefore mtDNA traces the ancestry on each person's direct maternal line. All living people descend on their direct maternal line from a woman estimated to have lived in Africa some 180,000 years ago and who is called mtDNA-Eve. The oldest branch point in the mtDNA tree is between Haplogroup L0 and its sister group L1'5.  Behar et al. estimated that the common ancestor of all L0 people lived in Africa about 140,000 years ago.

The vast majority of all living people descend from L1'5 through its major daughter groups L1, L2 and L3 that are found primarily in Africa. Two daughter groups of L3, named M and N, are believed to have migrated out of Africa approximately 60,000 years ago, and  most people of non-African ancestry are descended from haplogroups M and N.  The deepest branching of the human mtDNA tree can be seen at Phylotree, and the fine details of the L0 mtDNA tree can be seen here.

Several recent studies have evaluated haplogroup L0, most significantly, a 2008 study by Behar et al., "The dawn of human matrilineal diversity", and a 2012 study also by Behar et al., "A Copernican Reassessment of the Human Mitochondrial DNA Tree from its Root".  Haplogroup L0 is found at very low frequency throughout Africa and the Middle East. Some of its oldest branches are found among the Khoi and San peoples of south and east Africa.  Some major branches in the L0 tree are represented by only one mtDNA sample, and additional L0 test results are needed to fully understand the diversity and geographic distributions of subclades of L0.

Important:  If you have completed the mtDNA full genome FMS/Mega test Please consider sharing your FMS coding region results with the project administrators.  The coding region results are not shown on the project page and will not be made public, and by default they are also hidden from the project administrators. The coding region results are essential for identifying your lowest level daughter group, for estimating the age of each daughter group, for identifying new daughter groups and for filling in the fine details on the L0 tree.  To share your coding region results with the project administrators:

1. log into your FTDNA account, click on the tab "My Account" and select "Results Display Settings".

2. check the circle next to “Yes” for "Show my mtDNA Coding Region Mutations to Administrators of these Projects" for the L0 project, and click "Save".

If you have questions about your haplogroup or the L0 project please email one of the project administrators at the addresses above.
