Limitations of Testing

Test results are statistical probabilities of your origins and must be interpreted with caution. Human populations have been mixing since they began leaving Africa more than 100,000 years ago. A genetic marker can strongly suggest an origin, but is not 100% proof because no markers have so far been found that exist exclusively in a single group. If all the available tests are run on any given individual that still represents only a small percent of their total DNA.

Although you may be predominantly from one of the main human population groups, the markers you discover in yourself can be from other groups because of the extensive mixing of human populations. Scientists believe that we're all descended from fewer than 100,000 individuals and that we're all related!
