== Ape vs. Monkey ==
Apes and monkeys are both simian primates, but they belong to different biological groups.<ref name="ref1" /><ref name="ref2" /> While casual use sometimes conflates the terms, there are consistent anatomical and behavioral distinctions between them.<ref name="ref3" /> Apes are classified in the superfamily Hominoidea, while monkeys are split into two groups: New World monkeys (Platyrrhini) from Central and South America and Old World monkeys (Cercopithecoidea) from Africa and Asia.<ref name="ref2" /><ref name="ref4" /> Genetically, apes and Old World monkeys are more closely related to each other than either is to New World monkeys.<ref name="ref1" />

=== Anatomy and Locomotion ===
The most easily identifiable difference is the absence of a tail in apes. Monkeys almost uniformly possess tails, which can be prehensile for grasping in some New World species. This distinction is due to a genetic mutation in the ape lineage that led to the loss of the tail.

Structurally, apes have broad chests and highly mobile shoulder joints adapted for brachiation (swinging through trees). Their body plan is more upright, with a shorter, stiffer spine, which facilitates bipedal movement for short distances in some species. Monkeys, by contrast, have a narrower rib cage and a skeletal structure more akin to a four-footed mammal, built for running across branches rather than swinging beneath them.<ref name="ref3" />

=== Intelligence and Behavior ===
Apes are generally regarded as more intelligent than monkeys. They possess a larger brain relative to their body size, which is correlated with more advanced cognitive functions. Apes have demonstrated superior problem-solving skills, tool use, and more complex communication abilities. Some apes have even been taught to use human sign language. While monkeys exhibit complex social behaviors and can use vocalizations and body language, their cognitive and language skills are not as developed as those of apes.

=== Diversity and Distribution ===
The diversity of monkeys is far greater than that of apes. There are hundreds of monkey species found across the Americas, Africa, and Asia. Apes comprise a much smaller group, including gibbons (lesser apes), and the great apes: orangutans, gorillas, chimpanzees, bonobos, and humans. Wild apes are found only in Africa and Southeast Asia.<ref name="ref1" />
