Haplogroup I is a branch on the maternal tree of human kind. It is a child of haplogroup N1a1b It was likely born in the West Asia around 21,000 years ago. (Behar et al., 2012b)
Most researchers consider the birthplace of I to have been born in West Asia.
Behar et al., 2012b placed the birth of the H lineage between 17,300 and 24,500 years ago. This means the line was born in the Upper Paleolithic. At the time, people were using stone tools.
This timeline is an overview of the I branch's history from the first early people to the birth of the first woman from the I lineage. (View in new tab.)

mtDNA Haplogroup I 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 I Data Sources
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.
