( A) Selection on behavior in dogs predates modern breeds, which have existed for ~1% of dog history ( 10). The extent to which ancient behavioral propensities persist in modern breeds, defined primarily by aesthetics and often disconnected from functional behavioral selection, is unclear. Modern breeds retain these component motor patterns, but their contexts, sequences, and thresholds vary ( 12, 13). Before the 1800s, dogs were primarily selected for functional roles such as hunting, guarding, and herding ( 11)-heritable behaviors derived from the wolf predatory sequence ( 12). By contrast, the modern dog breed, emphasizing conformation to a physical ideal and purity of lineage, is a Victorian invention ( 10). Early humans may have given favored dogs increased access to limited resources, but there is little evidence of humans intentionally breeding dogs until 2000 years ago ( 8, 9). Prehistoric wolves likely adapted to use human refuse through changes in morphology, behavior, metabolism, and reproduction ( 3– 7). Modern dog breeds are less than 160 years old (~50 to 80 generations), a blink in evolutionary history compared with the origin of dogs more than 10,000 years ago ( 1, 2) ( Fig. White, Zhiping Weng, Andrés Colubri, Diane P.
