Unlike other domestic species selected for production-related traits, dogs were initially selected for their behaviors. In 2016, a study found that only 11 fixed genes showed variation between wolves and dogs. These gene variations were unlikely to have been the result of natural evolution and indicate selection on both morphology and behavior during dog domestication. These genes have been shown to affect the catecholamine synthesis pathway, with the majority of the genes affecting the fight-or-flight response (i.e., selection for tameness) and emotional processing.

Stillbirth was the most frequent cause of death, followed by infection. Mortality due to infection increased significantly with increases in inbreeding. This timing indicates that the dog was the first species to be domesticated in the time of hunter–gatherers, which predates agriculture.


Dog behavior is the internally coordinated responses of the domestic dog to internal and external stimuli. As the oldest domesticated species, dogs’ minds inevitably have been shaped by millennia of contact with humans. As a result of this physical and social evolution, dogs have acquired the ability to understand and communicate with humans more than any other species and they are uniquely attuned to human behaviors. Behavioral scientists have uncovered a surprising set of social-cognitive abilities in domestic dogs. These abilities are not possessed by the dog’s closest canine relatives or other highly intelligent mammals, such as great apes, but rather parallel to children’s social-cognitive skills. The timing and location of dog domestication is a matter of debate.
