higher. Thats how the now ubiquitous goldfish began its life. Such confounders make gwas in dogs prone to generating false-positive associations. At the other end of the continuum is the dolichocephalic appearance of breeds such as the Saluki, Borzoi, and collie. These kinds of conformational problems arent limited to dogs. Some canine skull conformations are named after their resemblance to human craniosynostoses, such as brachycephaly and dolichocephaly. Thus, development of dogs is highly attributed to domestication which has given the dog its current traits as a friendly animal to human being. Beyond understanding the mechanisms of dog craniofacial diversity, identification of causal genetics is necessary for understanding just what makes dog breeds so morphologically diverse in the first place. The young of many species look similar, with their large heads, big eyes, round foreheads, and snub noses. First came new colours, including a white goldfish and one with a black-and-white tortoiseshell pattern splashed across its back.

For instance, a study at the University of Washington, Bothell, in 2007 showed that we prefer penguin species that feature a dash of red or yellow on their bodies to those that are merely black and white. The same goes for any other benign modification. This latter approach demonstrated that principal component 1 (PC1) explained 76 of skull variance among skulls that were measured and described the continuum of morphological changes extending between brachycephalic and dolichocephalic dog breeds. We are drawn to creatures that are new, unusual, and rare. This suggests that, among incipient dogs, the skull was at the leading edge of several anatomical changes that would transform transaction words for essays wolves.
