A 60,000 year old pinkie finger. A 45,000 year old skull. A 40,000 year old tooth. Ancient DNA is demystifying our origins. Neanderthals, Denisovans. Migration, inter-breeding. Lost ancestors, “ghost DNA”. Harvard geneticist David Reich maps human history and origins – certitudes, surprise revelations, enduring questions. And answers how this lineage continues to shape modern humans – from disease to longevity, behaviour to intelligence.
