How many generations back does mitochondrial DNA (mtDNA) testing trace?
Mitochondrial DNA (mtDNA) testing covers both recent and distant generations.
- Matching on HVR1 means that you have a 50% chance of sharing a common maternal ancestor within the last fifty-two generations. That is about 1,300 years.
- Matching on HVR1 and HVR2 means that you have a 50% chance of sharing a common maternal ancestor within the last twenty-eight generations. That is about 700 years.
- Matching on the Mitochondrial DNA Full Genomic Sequence test brings your matches into times that are more recent. It means that you have a 50% chance of sharing a common maternal ancestor within the last 5 generations. That is about 125 years.
Mitochondrial DNA testing at Family Tree DNA also includes haplogroup testing. Your haplogroup represents your ancestral origins. (FTDNA)
The earliest migrations and expansions of archaic and modern humans across continents began 2 million years ago with the migration out of Africa of Homo erectus. This was followed by the migrations of other pre-modern humans including H. heidelbergensis, the likely ancestor of both anatomically modern humans and Neanderthals. Finally, the recent African origin paradigm suggests that Homo sapiens migrated out of Africa around 100,000 years ago, spread across Asia approximately 60,000 years ago, and subsequently populated other continents and islands.
Knowledge of early human migrations, a major topic of archeology, has been achieved by the study of human fossils, occasionally by stone-age artifacts and more recently has been assisted by archaeogenetics. Cultural and ethnic migrations are estimated by combining archaeogenetics and comparative linguistics. (Wikipedia)
For myself, I tested in 2011 with National Geographic. It was in the beginning of DNA testing. National Geographic, like Ancestry does not keep the samples and I was not able to get the full range of possibilities that are available today. It did give the Haplogroups. The migration route out of Africa where we all began, is pictured in this gallery. LONGEVITY. Yes, recently, I have also tested with FTDNA and 23 and Me. These companies keep the samples so I can upgrade. My parent’s engagement picture is there also. They were married 60 years. LONGEVITY. My son and I were able to travel to Bulgaria to research our maternal line. It goes back 45,000 years with ancestors along the Danube River where my grandmother was born. LONGEVITY. All the pictures in the gallery here are examples of longevity. Some are in Bulgaria, the maternal line and some in Scotland which is representative of my paternal Scottish lines. The photos represent the journey of our ancestors from the beginning of time, throughout the history of Europe and eventually emigration to America. For our paternal line, our ancestor from Scotland, born in 1627 in Blair Athol, Scotland. Daniel Robertson Robins was shipped from England as a prisoner in Cromwell’s Worcester Battle, to the Massachusetts Bay Colony in 1651 as an indentured servant at age 24. He served his time with the Nathaniel Foote family in New Haven, Connecticut, stayed 3 more years with them and married Hope Potter, one of the cousins. They moved to New Jersey and had a total of 9 children. We are part of the descendants of this line. Our maternal line is represented by the Bulgarian photos. Our maternal grandfather emigrated to Yakima, Washington in 1914. WWI started in that year and our grandmother could not emigrate to America until 1921. It was a long hard time for her to be stuck in Bulgaria. Our grandparents survived that hardship and descendants thrive today. LONGEVITY.
