Human evolutionary genetics
Human evolutionary genetics studies how one human genome differs from another human genome, the evolutionary past that gave rise to it, and its current effects. Differences between genomes have anthropological, medical and forensic implications and applications. Genetic data can provide important insight into human evolution.
