Ancient genomes reveal hybridisation between extinct short-faced bears and the extant spectacled bear (Tremarctos ornatus)

A. T. Salis, G. Gower, B. W. Schubert, L. H. Soibelzon, H. Heiniger, A. Prieto, F. J. Prevosti, J. Meachen, A. Cooper, K. J. Mitchell

The paper uses ancient nuclear genome sequences to show that the extant spectacled bear has ancestry from Pleistocene hybridization with an extinct short-faced bear lineage, causing discordance between mitochondrial and nuclear phylogenies.
