Recent advancements in DNA sequencing technologies and laboratory preparation protocols have rapidly expanded the scope of ancient DNA research over the past decade, both temporally and geographically. Discoveries include interactions between archaic and modern humans as well as modern human population dynamics, including those coinciding with the Last Glacial Maximum and the settlement history of most world regions. This new type of data allows us to examine the deep past of human population dynamics and sharpen the current understanding of our present. The continued development in the ancient DNA field has transformed our understanding of human genetic history and will keep uncovering the further mysteries of our recent evolutionary past.
