Who is Mitochondrial Eve and How is She Related to Us? 

Mitochondrial Eve is the oldest known women who is the closest known ancestor of all currently living humans. It is believe that she lived about 100,000- 200,000 years ago. Mitochondrial DNA  comes from the mothers side, and Mitochondrial Eve is the oldest women who shares common Mitochondrial DNA with current humans. Mitochondrial DNA is located in organelles called mitochondria. Since Mitochondrial DNA is past from mother to offspring without changing, every human being is directly descended from Mitochondrial Eve since they share the same Mitochondrial DNA.
