Apes are tailless Primates of the superfamily Hominoidea, a group that comprises the lesser apes, the gibbons, and the great apes, namely orangutans, gorillas, chimpanzees, bonobos, and humans. They are distinguished from monkeys by the absence of an external tail, a broad and flexible shoulder joint adapted for suspensory locomotion, a relatively large brain in proportion to body size, and an upright or semi-upright trunk posture. Native to the forests of Africa and Asia, apes share a recent common ancestry with humans, making them the closest living relatives of our species and central subjects in the study of primate evolution. Comparative work on skeletal and cranial anatomy, including features of the jaw and associated neurovascular structures, helps clarify how hominoids diverged and how human-specific traits arose. Genomic and chromosomal comparisons further illuminate evolutionary relationships, the reorganisation of chromosomes across lineages, and the genetic underpinnings of brain expansion and cognition. Apes display sophisticated behaviour, including tool use, social learning, complex group structures, and forms of communication that inform understanding of cognitive evolution. Many species face significant conservation pressures from habitat loss and other threats. As models for comparative anatomy, genetics, and behaviour, apes occupy a pivotal place in understanding human origins.
