Detailed explanation-1: -Dog breeding is another prime example of artificial selection. Although all dogs are descendants of the wolf, the use of artificial selection has allowed humans to drastically alter the appearance of dogs.

Detailed explanation-2: -An example of artificial selection-Dog breeding Domestication is the act of separating a small group of organisms (wolves, in this case) from the main population, and select for their desired traits through breeding.

Detailed explanation-3: -Most breeds were derived from small numbers of founders within the last 200 years, and since then dogs have undergone rapid phenotypic change and were formed into today’s modern breeds due to artificial selection imposed by humans.

Detailed explanation-4: -Artificial selection is an evolutionary process in which humans consciously select for or against particular features in organisms – for example, by choosing which individuals to save seeds from or breed from one generation to the next. People have been artificially selecting plants and animals for thousands of years.

Detailed explanation-5: -For over two centuries, dogs have been selectively bred for a variety of purposes: for work, sport, showing or companionship. Dogs have evolved from domesticating wolves. Although still unclear, it is generally believed that early humans were accompanied by one Palaeolithic dog ‘breed’.
