Double log plot of estimates of adult endocranial volume and body mass. Estimates were calculated from raw cranial landmark data provided in Geiger et al. [81]. Following Geiger et al. [81], breed refers to modern breed as recognized by kennel club standards, and village dogs refers to ‘premodern’ domestic dogs (NG = New Guinea). The latter are defined as populations that are geographically or culturally isolated from modern domestic breeds and that are situated in well-supported, basal positions on molecular phylogenetic trees [81]
