Most everyone knows that dogs are descended from wolves. Anyone who has ever seen a dog and a wolf also knows that more than 10,000 years of active and passive selection by humans has had a dramatic transformative impact on the anatomy and physiology of the dog. Ancestry is not destiny, ...
Genetic evidence suggests that dogs descended directly from wolves (Canis) and that the now-extinct wolf lineages that produced dogs branched off from the line that produced modern living wolves sometime between 27,000 and 40,000 years ago. The timing and location of dog domestication is a matt...

Scientists also say that every modern dog descended from approximately five female Asian wolves, the mother of all modern dogs. Scientists suspect dogs first set paws in North America by following settlers across a land bridge that once linked northern Asia and North America....

Wolves are charismatic emblems of wilderness. Dogs, which descended from wolves, are models of urbanity. Do free-ranging dogs revert to pack living or are their societies only reminiscent of a wolfish heritage? Focusing on behavioral ecology, this is the first book to assess societies of both ...

the wolf. They did this by analysing the genetic history through the DINA of 162 wolves from around the world and 140 domestic dogs representing 67 breeds. The research also confirms, for the first time, that dogs are descended only from wolves and do not share DNA with coyotes or jackals...
