Dogs are also viewed as being the single most genetically diverse species on Earth - largely thanks to human-imposed selective breeding, the vast array of dog breeds surpasses any other creature on the planet.

Dogs are also viewed as being the single most genetically diverse species on Earth - largely thanks to human-imposed selective breeding, the vast array of dog breeds surpasses any other creature on the planet. Due to selective breeding by man, however, many breeds of dog have significant [[gene|genetic]] disorders. These include hip dysplasia (common with German Shepherds), and respiratory problems caused by shortening of the face, as seen with Boxer dogs and the Bulldog's lip.
