How the dog came to be

DNA shows that dogs are not only close relatives of the gray wolf, but also the hybrid descendants of different gray wolf subspecies from all over the world. In earlier studies, it was thought that the ancestors of modern dogs were domesticated by humans from Western Europe about 16 to 11,000 years ago, and that the “ancient dogs” bred by humans earlier were extinct, leaving no surviving descendants. However, new research has shown that modern dogs have been domesticated at least twice.2 Genetic testing has revealed that many genotypes of Paleolithic European dogs are not found in modern European dogs. This means that ancient European dogs did not leave descendants, possibly because ancient European dogs were gradually replaced by Asian dogs during the Neolithic period.3. Through years of archaeological research, there is basically common knowledge – dogs evolved from gray wolves and were one of the first domesticated domestic animals by early humans. However, there are divergent opinions on when dogs became human companions.
