Using the tools of molecular genetics, DNA sequences can be compared among groups to test hypotheses about the evolutionary relatedness of organisms, and about the time that has elapsed since divergence. Molecular anthropology has made major contributions to understanding the migration and mixture patterns of human groups. It has also provided significant new insights into the rise and spread of modern humans and their relation to earlier human groups. As more data becomes available and better models are devised for their interpretation, the results are likely to become less provisional and more certain.
