What animal was artificially selected by humans?

One prominent example of an animal that has been artificially selected by humans is the domestic dog (Canis lupus familiaris). Over thousands of years, humans have selectively bred dogs for specific traits, such as size, temperament, and behavior, resulting in the diverse breeds we see today. This process of artificial selection has allowed for the development of dogs that Excel in various roles, from companionship to working alongside humans in tasks like herding, hunting, and service.
