Who is the extra one: dog, cat, wolf, calf, chicken? - briefly
The term "extra one" in this scenario refers to the animal that does not belong in the group based on common classifications. Among the listed animals—dog, cat, wolf, calf, and chicken—the calf is the odd one out. This is because the dog, cat, and wolf are all members of the Canidae family, while the chicken is a bird. The calf, however, is a young cow, which belongs to the Bovidae family.
Who is the extra one: dog, cat, wolf, calf, chicken? - in detail
To determine the extra one among dog, cat, wolf, calf, and chicken, it is essential to examine the characteristics and classifications of each animal. This analysis will reveal which one does not belong with the others based on shared traits.
Firstly, consider the classification of these animals. Dogs, cats, and wolves are all members of the order Carnivora. They are mammals that primarily consume meat. Dogs (Canis lupus familiaris) and wolves (Canis lupus) are closely related, both belonging to the Canis genus. Cats (Felis catus) are part of the Felidae family. These animals share several common traits, including:
- Mammalian characteristics such as fur, live birth, and nursing of young.
- Carnivorous diets, although domesticated cats and dogs may have varied diets.
- Similar anatomical features, such as sharp teeth adapted for meat consumption and retractable claws in the case of cats.
Next, examine the calf and the chicken. A calf is a young cow, and cows belong to the order Artiodactyla, which includes even-toed ungulates. Chickens are birds and belong to the class Aves. Neither calves nor chickens share the same order as dogs, cats, and wolves. Instead, they have distinct characteristics that set them apart:
- Calves are herbivores, primarily feeding on grass and other plant materials. They have hooves and are even-toed ungulates.
- Chickens are omnivores but are classified under Aves, possessing feathers, beaks, and laying eggs.
Given these distinctions, it is clear that the calf and the chicken do not belong to the same order as dogs, cats, and wolves. However, to identify the extra one among the listed animals, focus on the most divergent characteristics. The chicken stands out as the most distinct because it belongs to an entirely different class (Aves) compared to the others, which are all mammals. Additionally, chickens have unique features such as feathers and beaks, which are not present in mammals.
Therefore, the chicken is the extra one among the dog, cat, wolf, calf, and chicken. Its classification as a bird, along with its distinct physical characteristics, sets it apart from the other animals listed, which are all mammals.
