Why are monkeys in the animalia kingdom?

Monkeys belong to the Animalia kingdom because they are multicellular, eukaryotic organisms that exhibit characteristics typical of animals, such as the ability to move, consume organic material for energy, and respond to their environment. They are classified under the phylum Chordata and the class Mammalia, highlighting their vertebrate and mammalian traits, respectively. Monkeys share a common evolutionary ancestry with other animals, which places them firmly within the broader classification of the Animalia kingdom.
