The term 'Monkey Relative' can be summarized by the 3-letter word 'APE'. Apes are a group of primates that are closely related to monkeys, and include gorillas, chimpanzees, orangutans, gibbons, and bonobos. They are distinguished from other primates by their larger size, more complex brains, and lack of tails. Apes are found in tropical and subtropical regions of Africa and Asia, and are known for their intelligence and ability to use tools.
