Ancient DNA: time travels into our global evolutionary past
Abstract

The DNA double helix probably represents some of the most famous molecules on the planet. It is common to almost all forms of life and passes genetic information across generations. With the advent of next-generation DNA sequencing, this information can be deciphered in both a time- and cost-effective manner, including in the past, leveraging the ultrashort ancient DNA molecules preserved in the fossil record. Almost 20 years after the human genome was first drafted and three decades of research, ancient DNA research has now come of age. Thousands of ancient individual genomes have been characterized and many thousands more are being sequenced both in humans and non-human organisms. This wealth of genetic information allows the reconstruction of past population affinities at unprecedented detail, charting through space and time the history of population migration, admixture and adaptation to novel environments. The recovery of DNA from microbes, especially pathogens, also opens for a deeper understanding of the origins of major infectious diseases, the genomic changes underlying virulence, and their impact on human history. Applied at the scale of communities, ancient DNA has started to reveal how our microbial self but also how plant and animal communities have responded to major environmental crises and/or cultural transitions.
