Owners of dog species may disagree, but as far as biologists are concerned, all dogs are dogs. It takes a little digging to make sense. The dog is a direct descendant of the wolf, which proves that many wolves are fed into the gene pool of the dog over time.
The dogs are too young. Mammals require tens of thousands or more to evolve into unique species requiring the accumulation of mutations that cause modifications to the phenotype or its characteristics. Assessment of DNA from wolves and dogs and data, in addition to the remains, suggests that 000–40 years, about 16,000 years ago, was started by domestication with a dog breed.
We have accelerated the development of dogs, but not enough – Charles Darwin noted that the selection process was accelerated by choosing people for breeding according to other characteristics, while most of their genomes are still so many characteristics that were specific to what we call selection. Natural the choice takes time because it affects the new changes introduced into the gene pool during the process of DNA mutation.
The possibility of selection by other characteristics, while the majority of their genomes still very strongly indicate that the dog breeds are separated for a short time. This implies that the dog breed has different characteristics, while most of their genomes are still very similar to other characteristics, while most of their genomes are still very similar.
Huge physiological differences are mainly due to a relatively small number of loci, which show only a slight differentiation. These loci have a large phenotypic effect, which leads to a strong differentiation between the rocks in the genome. They’re artificial and possibly temporary – so if deformations are such as the characteristics of the coat and the flexibility of the ears.
Dog breeds are artificial and possibly temporary. So, if in the genome these strains are comparable with each other, how do the huge differences remain? The obvious answer is the linkage model that we impose on our dogs, we separate the strains, preventing crosses between them. Species are usually defined as groups of interbreeding natural populations.
Species are usually defined as groups of interbreeding natural populations, in cases where other factors can lead to reproduction. This requires hybrids between unique cases where other factors can make reproduction quite viable and cases where other factors can make reproduction completely. Obviously, in some cases, other factors can make pairing very difficult.
