The technology Our ability to sequence DNA has increased dramatically since the human genome was first sequenced 15 years ago. Out of Africa … and back In addition to their use in medical genetics, these data are providing us with an increasingly sophisticated view of human history. Ancient DNA also allows us to directly view the genomes of past populations.
