Editor's choice: ancient DNA
The past few years has seen a surge in papers where DNA has been successfully sequenced from specimens that died decades, hundreds or thousands of years ago. Reaching the point where researchers are able to extract such ancient DNA is the culmination of decades of collaborative work by chemists, biologists and archaeologists. As a result of these efforts we can now harness ancient DNA data to reveal new insights in anthropology, evolutionary biology and the archaeological sciences. This collection celebrates research on ancient DNA showcasing the methodologies that birthed the field and highlighting some of its most compelling findings in recent years.
