Dogs Domesticated Since

 

Study says dog race has been domesticated since long ago as human’s companion and according to the news, dogs were derived from a wolf race that has been domesticated and become the present dog race. The news said the present dog race come from domestication of wolf-derived animals that has evolved; and it present or evident on their genetic makeup or DNA.


Dogs are thought to have evolved from wolves that ventured into human camps, perhaps sniffing around for food. As they were tamed, they could then have served humans as hunting companions or guards. The results suggest all dogs derive from a single extinct wolf population - or perhaps a few very closely related ones. If there were multiple domestication events around the world, these other lineages did not contribute much DNA to later dogs. Dr Skoglund[ Dr Pontus Skoglund, co-author of the study and group leader of the Ancient Genomics laboratory at London's Crick Institute ]said it was unclear when or where the initial domestication occurred. "Dog history has been so dynamic that you can't really count on it still being there to readily read in their DNA. We really don't know - that's the fascinating thing about it."”(BBC)

 

“Greger Larson, a co-author from the University of Oxford, said: "Dogs are our oldest and closest animal partner. Using DNA from ancient dogs is showing us just how far back our shared history goes and will ultimately help us understand when and where this deep relationship began."”(BBC)


The origin of the domestic dog includes the dog's genetic divergence from the wolf, its domestication, and its development into dog types and dog breeds. The dog is a member of the wolf-like canids and was the first species and the only large carnivore to have been domesticated. Genetic studies show that dogs and modern wolves display reciprocal monophyly (separate groups), which implies that dogs are not genetically close to any living wolf population and that the wild ancestor of the dog is extinct. An extinct Late Pleistocene wolf may have been the ancestor of the dog, with the dog's similarity to the extant grey wolf being the result of genetic admixture between the two. In 2020, a literature review of canid domestication stated that modern dogs were not descended from the same Canis lineage as modern wolves, and proposes that dogs may be descended from a Pleistocene wolf closer in size to a village dog.(Wikipedia)

 

 The main point : Domesticated dogs were derived from a wolf race that has been domesticated since long ago.
