The macaques (/məˈkɑːk/ or /məˈkæk/[2]) constitute a genus (Macaca) of Old World monkeys of the subfamily Cercopithecinae. The twenty-two species of macaques are widespread over Earth. Macaques are of some interest to human researchers for their intricate social structures and their usefulness in animal testing, particularly regarding eyesight.

Description[edit]

Aside from humans (genus Homo), the macaques are the most widespread primate genus, ranging from Japan to Afghanistan and, in the case of the barbary macaque (Macaca sylvanus), to North Africa and Southern Europe. Twenty-two macaque species are currently recognized, including some of the monkeys best known to non-zoologists, such as the rhesus macaque (Macaca mulatta), and the barbary macaque, a colony of which lives on the Rock of Gibraltar. Although several species lack tails and their common names therefore refer to them as apes, these are true monkeys, with no greater relationship to the true apes than any other Old World monkeys.

In some species, skin folds join the second through fifth toes, almost reaching the first metatarsal joint.[3]

Social behavior[edit]

The premotor cortex of macaques is widely studied.[4]

Macaques have a very intricate social structure and hierarchy. If a macaque of a lower level in the social chain has eaten berries and none are left for a higher-level macaque, then the one higher in status can, within this social organization, remove the berries from the other monkey's mouth.[5]

Relation with humans[edit]

Several species of macaques are used extensively in animal testing, particularly in the neuroscience of visual perception and the visual system.

Nearly all (73–100%) pet and captive macaques are carriers of the herpes B virus. This virus is harmless to macaques, but infections of humans, while rare, are potentially fatal, a risk that makes macaques unsuitable as pets.[6]

A 2005 University of Toronto study showed urban performing macaques also carried simian foamy virus, suggesting they could be involved in the species-to-species jump of similar retroviruses to humans.[7]
