Namespaces Article Talk. There is clear evidence that dogs were derived from gray wolves during the initial phases of domestication and that no other canine species was involved. The first dogs were certainly wolflike, however the phenotypic changes that coincided with the dog—wolf genetic divergence are not known. Indicators of recent selection were shown by many of the 51 genomic regions that were associated with traits that define a breed, which include body size, coat characteristics, and ear floppiness. Later studies support coevolution in that dogs can discriminate the emotional expressions of human faces, [] and that most people can tell from a bark whether a dog is alone, being approached by a stranger, playing, or being aggressive, [] and can tell from a growl how big the dog is.

    Dogs and wolves are part of the rich palette of predators and scavengers that co-​evolved with herding ungulates about 10 Ma BP (million years before present).
    Animal domestication is a coevolutionary process in which a population responds to selective pressure while adapting to a novel niche that included another species with evolving behaviors.

    Oxford University Press is a department of the University of Oxford. Within the carnivores, the first domesticated animal would need to exist without an all-meat diet, possess a running and hunting ability to provide its own food, and be of a controllable size to coexist with humans, indicating the family Canidaeand the right temperament [57] : p with wolves being among the most gregarious and cooperative animals on the planet.

    A set of specimens dating 15, YBP have been confidently identified as domesticated dogs, based on their morphology and the archaeological sites in which they have been found. These genes are involved in the synthesis, transport and degradation of a variety of neurotransmitters, particularly the catecholamineswhich include dopamine and noradrenaline.

    Wolves are among the most gregarious and cooperative of animals on the planet, [58] [59] and their ability to cooperate in well-coordinated drives to hunt prey, carry items too heavy for an individual, provisioning not only their own young but also the other pack members, babysitting etc. This indicates that either dogs were domesticated much earlier than their first appearance in the archaeological record, or they arrived in the Arctic early, or both.

Human Ethology Bulletin, Volume 33, No 1,published March 25, Co-evolution of humans and canids: An alternative view of dog domestication. Over time, these tamed wolves would have shown their prowess at hunting, so humans kept them around the campfire until they evolved into.

    However, some ancestors adopted the pastoralist wolves' lifestyle as herd followers and herders of reindeer, horses, and other hoofed animals.

    Researchers have proposed that in the past a hunting partnership existed between humans and dogs that was the basis for dog domestication.

    The authors highlight the types of interactions, both good and bad, that can be had while living with wolf—dog crosses.

    This shared genetic trajectory might explain why Fluffy can be helped by antidepressant drugs, the authors hypothesize. The questions of when and where dogs were first domesticated have taxed geneticists and archaeologists for decades. Isotope analysis can be used to identify some chemical elements, allowing researchers to make inferences about the diet of a species.

    1. The maternal wolf sequence that contributed to them has not been matched across Eurasia [72] and its branch is phylogenetically rooted in the same sequence as the Altai dog not a direct ancestor. Some dog populations in the Neotropics and the South Pacific are almost completely derived from European dogs, and other regions show clear admixture between indigenous and European dogs.
