Competitive mapping allows for the identification and exclusion of human DNA contamination in ancient faunal genomic datasets

10 Pág.After over a decade of developments in field collection, laboratory methods and advances in high-throughput sequencing, contamination remains a key issue in ancient DNA research. Currently, human and microbial contaminant DNA still impose challenges on cost-effective sequencing and accurate interpretation of ancient DNA data.Genetic analyses were funded through a grant from the Swedish Research Council (VR grants 2012–3869 and 2017-04647) awarded to L.D..
