Thus, Vilà and his colleagues decided to compare the mitochondrial DNA of dogs and wolves in an attempt to understand the genetic consequences of these species' different lifestyles: domesticated versus wild. If dogs evolved from wolves, which seems to be the case, then wolves must have had the capacity for this diversity somewhere in their genomes. In fact, the variation among breeds of dogs is far greater than the variation among other completely distinct species in the family Canidae. One question that tugged at Swedish researcher Carles Vilà is how dogs can have such a wide variety of phenotypes-imagine a tiny Chihuahua standing next to a Great Dane, or a Chinese shar-pei peering from under its skin folds at an Old English sheepdog who peers back through its long hair. Increase in variability in the dog genome compared with the genome of theirĪncestral stock (Björnerfeldt et al., 2006).
