The rise of ancient genomics has revolutionised our understanding of human prehistory but this work depends on the availability of suitable samples. Here we present a complete ancienthuman genome and oral microbiome sequenced from a 5700 year-old piece of chewed birchpitch from Denmark. We sequence the human genome to an average depth of 2.3× andfindthat the individual who chewed the pitch was female and that she was genetically moreclosely related to western hunter-gatherers from mainland Europe than hunter-gatherersfrom central Scandinavia. We alsofind that she likely had dark skin, dark brown hair and blueeyes. In addition, we identify DNA fragments from several bacterial and viral taxa, including Epstein-Barr virus, as well as animal and plant DNA, which may have derived from a recentmeal. The results highlight the potential of chewed birch pitch as a source of ancient DNA.
