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)
