Monkey, gorilla and gibbons belong to which of the following order?

The correct answer is primata.

To understand why monkeys, gorillas, and gibbons belong to the order Primata (primates), let's break down the biological classification system (taxonomy):

1. Kingdom: Animalia (Animals)
2. Phylum: Chordata (Animals with a backbone/notochord)
3. Class: Mammalia (Mammals, characterized by warm blood, hair, and mammary glands)
4. Order: Primata (Primates, characterized by large brains, complex social behaviors, grasping hands and feet, and forward-facing eyes)
5. Family: Different families (e.g., Hominidae for gorillas and humans, Hylobatidae for gibbons)

Let us analyze the given options to see why "primata" is the correct classification:
- carnivora: This is an order of placental mammals that includes meat-eating animals like lions, wolves, and bears.
- mammalia: This is a class, not an order. While monkeys, gorillas, and gibbons are indeed mammals, the question asks for their order.
- primata: This is the correct biological order that includes lemurs, lorises, tarsiers, monkeys, gibbons, gorillas, and humans.
- hominidae: This is a family (great apes) within the primate order. Gibbons belong to a different family called Hylobatidae, so hominidae does not include all three animals mentioned.

Therefore, monkey, gorilla, and gibbons all belong to the taxonomic order Primata.
