Evidence from DNA

Our DNA is passed from generation to generation. This genetic information is copied perfectly most of the time, but occasionally small changes (mutations) occur that are then passed on. As groups of humans moved around the world over many thousands of years, they acquired different mutations in their DNA. The more DNA differences there are between different populations, the more distantly related they are.

Scientists study human origins by looking at DNA differences between different populations.
