New breakthroughs in ancient DNA are causing a revolution in the study of human evolution. By sequencing ancient DNA from the fossils of human ancestors, researchers have recently discovered new types of ancient humans and revealed interbreeding between our ancestors and our archaic cousins, including Neandertals. They are exploring how that genetic legacy is shaping our health and appearance today. And now that investigators can sequence entire ancient populations, ancient DNA is revealing that humans on every continent are a complex mix of archaic and modern DNA. Ancient DNA is enabling researchers to answer questions they could not previously address. As a result, archaeologists, anthropologists, and population geneticists are now seeking collaborations with ancient DNA researchers.
