The Question Of Mitochondrial DNA

The most publicly discussed scientific finding from the Kwäday Dän Ts’ìnchi project was the mitochondrial DNA analysis and the identification of seventeen living people who shared closely matching maternal-line DNA sequences with the ancient man.

Understanding what this finding actually means — and what it does not mean — requires understanding how mitochondrial DNA works and what it can and cannot establish about biological relationships.

Mitochondrial DNA (mtDNA) is the genetic material housed in the mitochondria — the energy-producing structures present in virtually every cell of the body.
