After analyzing 49,024 locations of dog DNA single nucleotide polymorphisms (SNPs), Larson and his colleagues took the DNA from 1,375 dogs of 121 breeds, and 19 wolves. They discovered that six breeds were less genetically mixed. These six breed include the basenji, shar-pei, Saluki, Akita, Finnish spitz and Eurasier. They also found that dogs more genetically mixed were not from places where the ancient fossils have been found.

In the Origin Of Domestic Dogs, the University of Turku in Finland analyzed mitochondrail DNA from 18 fossils and compared ancient sequences to those from 49 modern wolves and 77 modern dogs. This new data pinpointed Europe as the major nexus of dog domestication. It identified four clades of modern dogs that are most closely related to ancient European dogs rather than wolves from China or the middle east. The largest clade of domestic dogs last shared a common ancestor 18,800 years ago and shared a common ancestor with wolves around 32,100 years ago. They must have domesticated somewhere in between this window.
In one year from the article of "Deeper Digging Needed to Decode a Best Friend's Genetic Roots" and the "Origin of Domestic Dogs," they have been able to narrow the origin of the domestication of dogs. The ancient dog fossils were key to understanding the origins of dogs.
