The ability to extract DNA from ancient fragments of biological material has revolutionized our understanding of recent evolutionary history, including human evolution and phylogeography. Analysis of ancient DNA in tandem with radiocarbon dating, along with traditional archeological techniques, has led to a flurry of discoveries. With us to discuss this research is Maanasa Raghavan. Maanasa is a Neubauer Family Assistant Professor of Human Genetics at the University of Chicago.
