Sequencing genomes of ancient specimens, including human ancestors, can provide rich insights into evolutionary histories. However, ancient DNA samples are frequently degraded, damaged and contaminated with ancient and modern DNA from various sources. This Review describes the methodological and bioinformatic advances that allow these challenges to be overcome in order to process and sequence ancient samples for genome reconstruction, as well as recent progress in characterizing ancient epigenomes.
