The enigma of the Předmostí protodogs. A comment on Prassack et al. 2020

Prassack et al. (2020) analyzed dental microwear in a sample of canids from the Gravettian site of Předmostí that had been identified as either Paleolithic dogs or Pleistocene wolves (n = 10 in each group), accepting that the morphological differences between the groups validly distinguished the (self-domesticating) protodogs from wolves. The authors then concluded that differences in one m2 microwear pattern separated those groups and indicated enhanced anthropogenic based durophagy in the putative protodogs. The study also inferred protodog diets from another isotope study.
