DNA ties us all together. Written in our DNA, our genetic code, we have a historical document that takes us back in time to the very earliest days of our species.
A family tree for humanity for everybody alive today is a work in progress as a result of the Genotype Project. Based on looking at the pattern of genetic variation and assessing the relative ages when they occurred throughout our history, the project shows how each one of us in the world falls into a lineage somewhere on this tree. What’s the take-home message? Within the last 200,000 years, we all share an ancestor, a single person -Mitochondrial Eve- in Africa, an African woman who gave rise to all the mitochondrial diversity in the world today.
