What is the pattern of evolution of dogs?
The dog, Canis familiaris, is a direct descendent of the gray wolf, Canis lupus: In other words, dogs as we know them are domesticated wolves. Not only their behavior changed; domestic dogs are different in form from wolves, mainly smaller and with shorter muzzles and smaller teeth. Darwin was wrong about dogs.

What is the variation of dogs?
Dog breeds vary not only in overall body size, but also in leg length, head shape and many other body features, all of which are controlled at least in part at the genetic level. The amount of morphologic variation observed in the dog is reported to surpass that of all living land mammals.
How many patterns does a dog have?
It reveals structural variants that control expression of the agouti signaling protein, or ASIP, gene at two separate locations to produce five distinctive dog color patterns. These different patterns are widespread, occurring in hundreds of dog breeds and hundreds of millions of dogs around the world.
