Quizplus · Accepted Answer

Dogs, as a species, have a tremendous amount of genetic diversity that has been honed for centuries through selective breeding. This makes them a fascinating subject for anthropologists studying the relationship between genotype and phenotype, especially as it relates to the evolution of the human species. By studying dog breeds, anthropologists can learn how certain physical and behavioral traits are passed down from generation to generation and how they are influenced by environmental factors.
