Unresolved reasons and mechanisms of dog domestication

Determine the reasons and mechanisms underlying the domestication of the domestic dog (Canis lupus familiaris) by humans, including the specific causal processes that led to domestication.

Background

The paper reviews current understanding of dog domestication, noting broad agreement on an ancient origin but emphasizing that the drivers and processes that produced domesticated dogs are debated.

Despite numerous genetic, archaeological, and behavioral studies, the specific selective pressures, human-dog interactions, and mechanistic pathways that initiated and sustained dog domestication are still unresolved, which the authors explicitly flag as unclear.

While the domestication of approximately twenty animal species to date has primarily been for purposes such as food, clothing, and transportation (Beaver, 2009), the reasons and mechanisms behind the domestication of dogs remain unclear.
