The Allen Ancient DNA Resource (AADR) is a curated compendium of ancient human genomes, providing a centralized, version-controlled dataset of over a million single nucleotide polymorphisms (SNPs) from more than 10,000 individuals with published ancient DNA data. Since 2019, the AADR has been maintained to offer a standardized, easily analyzable format for researchers. The dataset includes data from diverse sources, including public repositories and in-house sequencing, and integrates modern human genomes for comparative analysis. The AADR includes detailed metadata such as archaeological context, geographic location, chronological information, and contamination estimates. It also provides various metrics, including molecular sex determination, cytosine-to-thymine rates, and contamination levels. The dataset is available on Harvard Dataverse and includes multiple file formats for ease of use. The AADR is continuously updated with new data and includes a mitochondrial repository for ancient individuals. Researchers are encouraged to cite both the AADR and the original publications that produced the data. The AADR aims to provide a comprehensive and accessible resource for the study of ancient human genomes.The Allen Ancient DNA Resource (AADR) is a curated compendium of ancient human genomes, providing a centralized, version-controlled dataset of over a million single nucleotide polymorphisms (SNPs) from more than 10,000 individuals with published ancient DNA data.
