《自然-通讯》本周发表的一项研究A 5700 year-old human genome and oral microbiome from chewed birch pitch从一个被咀嚼过的桦树沥青样本中得到了一名5700年前丹麦人的全部基因组。对桦树沥青中含有的植物、动物和微生物DNA进行分析还揭示了这位个体的口腔微生物组和可能的饮食来源。
摘要: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 ancient human genome and oral microbiome sequenced from a 5700 year-old piece of chewed birch pitch from Denmark. We sequence the human genome to an average depth of 2.3× and find that the individual who chewed the pitch was female and that she was genetically more closely related to western hunter-gatherers from mainland Europe than hunter-gatherers from central Scandinavia. We also find that she likely had dark skin, dark brown hair and blue eyes. 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 recent meal. The results highlight the potential of chewed birch pitch as a source of ancient DNA.
