Mitochondrial DNA is passed from mother to children, both male
and female, unchanged and it mutates at a predictable rate;
i.e., the more the genetic mutations in the DNA, the more
ancient the origin of the population. Using these facts, some
scientists are studying mitochondrial DNA to try to trace back
the origins of the human race. Using this method, the scientists
have traced the human race to one female in Africa several
million years ago. Then they traced the migration patters of her
descendants as they spread across the earth. The Real Eve is a
fascinating documentary presenting a new and controversial
theory of human evolution. It does what all good documentaries
do, it makes you think, and it entertains at the same time.
