Previous genetic studies of dog lineages have concluded that domestication occurred in Southern China around 16,500 years ago, but the earliest archaeological evidence of domesticated canines is found in Europe and Siberia.
There is point-two-percent difference between the DNA of a domestic dog, and the DNA of a grey wolf. The difference between a coyote and domestic dog is higher, at four per cent. Domestic dogs are said to originate from wolf cubs that were used as guards by humans over 40,000 years ago in southeast Asia.Since that time wolves have been domesticated and used have been used by humans for hunting and herding.There are around 400 modern breeds of domesticated dogs.ogs are seen as loving creatures, whereas their wolf cousins are considered wild and ferocious. A study from Massachusetts has discovered this may be due to their early stages of development. Evolutionary biologist Dr Kathryn Lord studied how seven wolf pups and 43 dogs reacted to smells, sounds and visual stimuli.
