History of the Domestic Dog 

DNA analysis has proved that dogs are decedents from the grey wolf (Canis lupus). DNA research published in 1997 found no evidence that dogs have ancestors with any other species than the grey wolf. Fossils of humans and wolves have been discovered dating back 400,000 years. It has been suggested by Stephen Budiansky in his book ‘the truth about dogs’ that the genetic move from wolf to a new species happened 100,000 years ago and called ‘proto-dogs’. He also claims it was the dog who chose us; they hung around campfires begging food. This theory can be substantiated if we think how strong and powerful the wolf and dog are, is it then not more unlikely that humans could forcibly domesticate them? The proto-dogs appearance remained unchanged for many years, and domesticated dogs go back around 20,000 years. Brian Hare, director of the Duke University Canine Cognition Centre, suggest that the physical changes occurred due to a process of self-domestication.
