What is a dog really?
Correct Answer
E. A domesticated form of the gray wolf
Explanation
A dog is considered a domesticated form of the gray wolf because scientific research and genetic studies have shown that dogs are descended from wolves. Over thousands of years, humans selectively bred wolves for specific traits, resulting in the domestication of dogs. While dogs have evolved to be distinct from wolves in terms of appearance and behavior, they still share a common ancestor. Therefore, a dog can be defined as a domesticated form of the gray wolf.

Over how many years has the dog been domesticated?
Correct Answer
E. Over a span of 15000 years
Explanation
Dogs have been domesticated for over a span of 15000 years. This means that humans have been living and working with dogs for thousands of years, forming a strong bond and partnership. The domestication of dogs began when humans started to tame and breed wolves, gradually selecting for specific traits that were desirable for various purposes such as hunting, herding, and companionship. This long period of domestication has resulted in the wide variety of dog breeds that we see today, each with their own unique characteristics and abilities.
