Dogs Evolution Infographic
How did we take a wolf and come up with bulldogs, Yorkshires, collies, golden retrievers, whippets, goldendoodles, and otterhounds? Designed by Parisian artist Alice Bouchardon, the “Evolution of Dogs” attempts to explain the complicated Darwinian evolutions that resulted in various kinds of dog breeds.
Based to a genetic research by UCLA in 2010, what we call dogs today were probably originated as wolves about 33,000 years ago in the Middle East. But precisely how is a creature like a pug, a bull terrier, or even a coyote linked to those wolves? In Bouchardon’s infographic, the gray wolf’s heritage is divided into 11 different families of dogs, varying from hounds and herding dogs to toy dogs and mastiffs.
Nowadays, there are more than 400 breeds and they may all approximately be characterized by the shapes of their skull. The most wolf-like dogs, like Siberian Huskies, have dolichocephalic skulls, which dedicates the largest proportion of the skull to the nasal cavity for smelling and hunting. Mesocephalic skulls are the most common, and dedicate equal portions of the skull to cranium and nasal cavity, while brachycephalic skulls are ones like in the pug and bulldog, where the snout is either flat or nonexistent.
