Environmental genomics of Late Pleistocene black bears and giant short-faced bears.

ABSTRACT: Analysis of ancient environmental DNA (eDNA) has revolutionized our ability to describe biological communities in space and time,^1-3 by allowing for parallel sequencing of DNA from all trophic levels.^4-8 However, because environmental samples contain sparse and fragmented data from multiple individuals, and often contain closely related species,⁹ the field of ancient eDNA has so far been limited to organellar genomes in its contribution to population and phylogenetic studies.^5,6,10,11 This is in contrast to data from fossils^12,13 where full-genome studies are routine, despite these being rare and their destruction for sequencing undesirable.^14-
