Dogs (Canis lupus familiaris) descend from wolves (Canis lupus) sharing the same ecological niche of cooperative hunters, as humans. Initially, humans and wolves were competitors starting interspecific communication in order to avoid risk of injury. The evolutionary continuity of mammalian brains enabled interspecific prosocial contacts between both of them, which reduced stress, and enabled behavioral cultures leading to genetic isolation of those wolves. Dogs are the first domesticated animal… 
Did Dog Domestication Contribute to Language Evolution?
This work hypothesizes about a parallel domestication of humans and dogs, and more specifically, about a positive effect of the authors' interaction with dogs on human self-domestication, and ultimately, on aspects of language evolution, through the mechanisms involved in the control of aggression.
Intraspecific Motor and Emotional Alignment in Dogs and Wolves: The Basic Building Blocks of Dog–Human Affective Connectedness
A possible developmental trajectory of emotional sharing phenomena is delineated by using the domestic dog, a valid example of empathic predisposition towards individuals belonging both to the same and the different species, to investigate if the ability to emotionally engage with conspecifics is evolutionary rooted in canids and if provides the basis for the development of inter-specific emotional sharing (dog–human).
The relationship between functional breed selection and attachment pattern in family dogs (canis familiaris)
Abstract Adult dogs show similar behaviour pattern towards their owners as human infants towards their caregivers among experimental conditions, where the attachment behaviour is activated because of
Grumpy Dogs Are Smart Learners—The Association between Dog–Owner Relationship and Dogs’ Performance in a Social Learning Task
The results indicate that dog–human relationship has an integral role in the complex social behaviour of dogs, which warrants for the need of further empirical testing of the associations between social dynamics in dogs and their relationship with humans, including problem behaviours.
The future of biology from a canine perspective.


Is dog domestication due to epigenetic modulation in brain
Dog domestication is suggested to be essentially an epigenetic based process that changes the interactions of the HPAaxis and the 5-Hydroxytryptamine (5-HT) system that allows less stressed human-associated wolf clans to extend their social skills to interactions with humans.
Wolves Are Better Imitators of Conspecifics than Dogs
6-month-old wolves outperform same aged dogs in a two-action-imitation task following a conspecific demonstration and offer an alternative perspective to domestication by emphasizing the cooperativeness of wolves as a potential source of dog-human cooperation.
Animal evolution during domestication: the domesticated fox as a model
Changes in behavior, morphology and physiology that appeared in the fox during its selection for tameability were similar to those observed in the domestic dog, and the developmental, genetic and possible molecular genetic mechanisms underlying these changes are discussed.
The self-domestication hypothesis: evolution of bonobo psychology is due to selection against aggression
The self-domestication hypothesis provides a plausible account of the origin of numerous differences between bonobos and chimpanzees, and note that many of these appear to have arisen as incidental by-products rather than adaptations.
From wild wolf to domestic dog: gene expression changes in the brain.
It is indicated that rapid changes in brain gene expression may not be exclusive to the development of human brains and may provide a common mechanism for rapid adaptive changes during speciation, particularly in cases that present strong selective pressures on behavioral characters.
Integrating social ecology in explanations of wolf–dog behavioral differences
Whereas studies in comparative cognition normally invoke ecology and social organization to account for differences in social behaviour and cognition across species, dog–wolf differences have so far
Social Cognitive Evolution in Captive Foxes Is a Correlated By-Product of Experimental Domestication
The results suggest that sociocognitive evolution has occurred in the experimental foxes, and possibly domestic dogs, as a correlated by-product of selection on systems mediating fear and aggression, and it is likely the observed social cognitive evolution did not require direct selection for improved social cognitive ability.
Selection for tameness, a key behavioral trait of domestication, increases adult hippocampal neurogenesis in foxes
A controlled within‐species comparison of adult hippocampal neurogenesis in farm‐bred foxes (Vulpes vulpes) that differ in their genetically determined degree of tameness is presented.
The genomic signature of dog domestication reveals adaptation to a starch-rich diet
The results indicate that novel adaptations allowing the early ancestors of modern dogs to thrive on a diet rich in starch, relative to the carnivorous diet of wolves, constituted a crucial step in the early domestication of dogs.
Comparative social cognition: From wolf and dog to humans
Dogs’ special domestication processes, their natural socialization to humans, and the possibility of tracing evolutionary changes by comparing dogs’ behavior to that of wolves, make dogs altogether
