Human Mitochondrial DNA (mtDNA) is in every person on the planet. A mother passes mtDNA to her children. The male offspring carries it but doesn't pass it, the female offspring does.

In humans, there are 100-10,000 separate copies of Mitochondrial DNA (mtDNA). This is found in every cell of every living organism. This DNA is passed on almost completely unchanged, with the exception of random mutations.

The fact that mtDNA is passed on maternally, it allows researchers to trace family lineage far back in time. You can get your own DNA analyzed through Get your DNA tested at Ancestry.com DNA testing.

We all have relation to a woman scientists estimate to be 140,000 years old. This woman, "Mitochondrial Eve", is the maternal ancestor to us all. We can all be linked to her. Mitochondrial Eve

It is stated that "Eve" is our Most Recent Common Ancestor as is Y chromosomal "Adam". Adam was estimated being alive around 60,000 years ago.

In the entire world there are at least 42 of these common maternal ancestors though these "7 sisters" make up 95% of Europe's population. 9 common maternal ancestors are found in Japanese clans alone.

Haplogroups are groups made statistically by matching DNA.
