Here, we demonstrate that genes involved in glutamatemetabolism, which account partially for fear response, indeed show the greatest population differentiation by whole-genome comparison of dogs and wolves. However, the changing direction of their expression supports a role in increasing excitatory ...
Dogs, the first animals domesticated by humans, evolved from wolves.▉The apparent emergence of protodogs (a stage between wolf and dog) between 26,000 and 30,000years ago is followed by a gap of over ten millennia, with no additional, solid evidence indicating the presence of dogs until 1...
Despite some opinion that dogs were domesticated independently in the Old World and in the New, most consider domestication to have happened only once, possibly around 15,000 years ago in Asia. I propose that dogs were pre- domesticated either from wolves and/or wi...

Dogs’ increased human-directed sociability compared to wolves may be the result of increased oxytocin system activity and decreased stress responses, but comparative studies accounting for life experience are lacking. We compared hand-raised, pack-living wolves’ and dogs’ behavior and hormone concentr...
The process of breeding species to live with humans. The domestication of wolves likely led to modern dogs. 7 Tame Conditioning a wild animal to accept human presence. He tamed a wild parrot to sit on his hand. 9 Domestication Genetically modifying traits over generations. Domestication has made...
由第一段中 “A tiny proportion of the genome differentiates dogs from wolves, and yet millions of dogs are comfortably curled up in our homes, while wolves move around at the edge of extinction.”以及第三段中 “Dogs, in fact, did not descend from wolves. Instead, dogs and wolves shared...
domestication of dogs. This SDH is most closely related to that found in wolves from the Middle East, suggesting that region as its origin. Provided that Middle Eastern wolves today most closely resemble Middle Eastern wolves of yesteryear, then a fair inference is that the SDH descends from ...
Domestication of dogs from their shared ancestors with wolves occurred more than 15,000 years ago and affected many characteristics of the species. We analyzed the blood RNA sequence data of 12 dogs and 11 wolves from Europe and Asia to shed more light on the domestication history of dogs. We...
