Step-by-step explanation:
Dog-faced Monkey of the Genus Papio
The correct answer to the question of identifying the “dog-faced monkey of the genus Papio” is A) Baboon. Baboons are part of the Cercopithecidae family, which includes the Old World monkeys of Africa and southern Asia. Baboons have distinctive facial features, dog-like muzzles, and powerful builds. They are different from macaques, gibbons, and capuchin monkeys. Macaques are also part of the Cercopithecidae family, but they do not belong to the genus Papio. Gibbons, classified under the family Hylobatidae, are lesser apes and lack tails, while capuchins are New World monkeys with prehensile tails.
Baboons are highly adaptable, live in diverse habitats, and have hierarchical social structures. They can be distinguished from the other options provided by their size, face, and behavior. While macaques are widespread in Asia and known for species like the Japanese macaque, gibbons are known for their brachiating locomotion and lesser ape classification. Capuchin monkeys, on the other hand, are recognized for their manual dexterity and are often trained to assist individuals with disabilities.
