Great apes, for example, are able to recognize themselves in mirrors (monkeys and other nonhumans cannot, with the exception of bottlenose dolphins). The great apes include gorillas, chimpanzees, orangutans, and bonobos. They are much smaller than great apes and they spend almost all their time in trees. Do gibbons have tails? Apes are way larger than monkeys and unlike monkeys they do not have tails. Our editors will review what you’ve submitted and determine whether to revise the article. In modern usage, however, yuán is a generic word for ape. Living in small family groups, gibbons are mostly monogamous. Gibbon (surname))[5] originally from an Orang Asli word. Gibbons' diets are about 60% fruit-based,[27] but they also consume twigs, leaves, insects, flowers, and occasionally bird eggs. [32][33], Most species are either endangered or critically endangered (the sole exception being H. leuconedys, which is vulnerable), primarily due to degradation or loss of their forest habitats. The common ancestor of hominoids is shown to have a minimum of 24 major chromosomal rearrangements from the presumed gibbon ancestor’s karyotype. The decrease in gibbon population is also largely due to habitat loss as a result of urban expansion and land conversion, mostly for agriculture. Baylor College of Medicine. The classification of the great apes has been revised several times in the last few decades; these revisions have led to a varied use of the word "hominid" over time. Zoos often receive gibbons of unknown origin, so they rely on morphological variation or labels that are impossible to verify to assign species and subspecies names, so separate species of gibbons commonly are misidentified and housed together. [2], The family is divided into four genera based on their diploid chromosome number: Hylobates (44), Hoolock (38), Nomascus (52), and Symphalangus (50). The controversy often continues and so you will find information out there about them in both categories. They have lighter bodies and smaller social groups than great apes. Fact #2 – Gibbons mostly move by swinging No, gibbons do not make good pets. Apes (including humans) possess the same general features that all primates share but they differ from other primates in a number of distinctive ways. Hominidae - wikipedia, the free encyclopedia "Great apes", "Hominid", and "Hominids" redirect here. [6], Whole genome molecular dating analyses indicate that the gibbon lineage diverged from that of great apes around 16.8 million years ago (Mya) (95% confidence interval: 15.9 – 17.6 Mya; given a divergence of 29 Mya from Old World monkeys). Updates? Gibbons, like the great apes (gorillas, orangutans, chimpanzees, and bonobos), have a humanlike build and no tail, but gibbons seem to lack higher cognitive abilities and self-awareness. Gibbon, (family Hylobatidae), any of approximately 20 species of small apes found in the tropical forests of Southeast Asia. Western Hoolock gibbons, also known as white-browed gibbons, are the only apes that live in the Indian sub-continent. Encyclopaedia Britannica's editors oversee subject areas in which they have extensive knowledge, whether from years of experience gained by working on that content or via study for an advanced degree.... Where can you find a capybara? “Today, gibbons and orangutans can both be found in Sumatra and Borneo in Southeast Asia, and the oldest fossil apes are from Africa. Unlike great apes, gibbons do not build nests. ScienceDaily. These fascinating apes are monogamous and mate for life. Gibbons are referred to as small apes along with their siamang cousins. Mariani Ramli, known as Bam to her friends, is a Malaysian conservationist and the founder of the Gibbon Protection Society Malaysia (GPSM), the only NGO in Peninsular Malaysia dedicated to conserving their resident gibbons. Planet of the apes: Gibbons are last ape to have genome revealed. These very acrobatic primates live in southeast Asia. Reuters. Later on, gibbons became a popular object for Chinese painters, especially during the Song dynasty and early Yuan dynasty, when Yì Yuánjí and Mùqī Fǎcháng excelled in painting these apes. There are two main groups of apes, the Great Apes and the Lesser Apes. They are sometimes hunted for food, but more often they are killed for their supposed medicinal properties; their long arm bones are especially prized. The vocal element, which can often be heard for distances up to 1 km (0.6 mi), consists of a duet between a mated pair, with their young sometimes joining in. Thus, gibbons are organisms that genetics research could be focused on to broaden the implications to human diseases related to chromosomal changes like cancer, such as chronic myeloid leukemia.

Corrections? There are 18 different species of gibbons, and each species is different from the next. Gibbons are small apes found throughout Southeast Asia. One of them is TBX5, which is a gene that is required for the development of the front extremities or forelimbs such as long arms. "[24][25], Gibbons are among nature's best brachiators. Single offspring are born after about seven months’ gestation and take seven years to mature. [2][11] There is an extinct fifth genus named Bunopithecus which is either a gibbon or gibbon-like ape. 1 fossil of a different genus dating from the Pleistocene. The remaining two groups each contain only one or two species. How many cervical vertebrae do giraffes have? There are two extant branches of the superfamily Hominoidea: the gibbons, or lesser apes; and the hominids, or great apes. Interspecific hybrids, hybrids within a genus, are also suspected to occur in wild gibbons where their ranges overlap. The separation of the gibbons (Hylobatidae) from the great ape/human stock (Hominidae) is at present not documented by fossils; indeed, whether there are any fossil gibbons known at all before the Pleistocene is still disputed.…, Family Hylobatidae (gibbons) 4 genera, approximately 20 species. The smallest apes are the gibbons. [10], At the species level, estimates from mitochondrial DNA genome analyses suggest that Hylobates pileatus diverged from H. lar and H. agilis around 3.9 Mya, and H. lar and H. agilis separated around 3.3 Mya. Appearance. To reach the common gibbon ancestor’s karyotype from today’s various living species of gibbons, it will require up to 28 additional rearrangements. Ms Williams said COVID-19 might be one of the diseases gibbons could be susceptible to. E. J. Brill, Leiden, Holland. Phylogenet. [3] Like all apes, gibbons are tailless. They live across 11 countries including India, Myanmar, China, Indonesia, Lao PDR, Thailand, Malaysia, Brunei Darussalam, Bangladesh, Vietnam and Cambodia, mainly in tropical evergreen rainforests. These very acrobatic primates live in southeast Asia. The English word 'gibbon' is said to be a reborrowing from French, and folk etymology (cf. Gibbon, (family Hylobatidae), any of approximately 20 species of small apes found in the tropical forests of Southeast Asia. The gibbons are also known as the small apes. They are strongly territorial, and defend their boundaries with vigorous visual and vocal displays. With a genome that has a 96% similarity to humans, the gibbon has a role as a bridge between Old World Monkeys like macaques and the great apes. The great apes are better known in comparison and include the orangutans, chimpanzee, bonobo and gorillas. Gibbons and Siamangs live in Asia. They can also make leaps up to 8 m (26 ft), and walk bipedally with their arms raised for balance. The current conservation status of gibbon species is alarming - all but one is listed as either Endangered or Critically Endangered. Gibbons are intelligent and social animals. Test your knowledge of mammals by taking this quiz. The LAVA transposon increases mutation rate and thus is supposed to have contributed to the rapid and greater change in Gibbons in comparison to their close relatives, which is critical for evolutionary development. There are about twelve species (kinds) of gibbon, making them the largest group in the ape... Habitat and distribution (where they are found). Tarsiers are highly arboreal primates that have expanded pads on the digits to improve grasping, whereas many other arboreal mammals have claws or well-developed nails.…. Gibbons (/ˈɡɪbənz/) are apes in the family Hylobatidae (/ˌhaɪləˈbætɪdiː/). Gibbons live in subtropical and tropical rainforest from eastern Bangladesh to Northeast India to southern China and Indonesia (including the islands of Sumatra, Borneo, and Java). (2014, September 10). Gibbons are monogamous (a rare trait among primates) and live in family groups consisting of an adult pair and their young offspring. Depending on the species and sex, gibbons' fur coloration varies from dark to light brown shades, and any shade between black and white, though a completely "white" gibbon is rare. Early Chinese writers viewed the "noble" gibbons, gracefully moving high in the treetops, as the "gentlemen" (jūnzǐ, 君子) of the forest, in contrast to the greedy macaques, attracted by human food. A special feature of the LAVA transposon is that it positioned itself precisely between genes that are involved in chromosome segregation and distribution during cell division, which results in a premature termination state leading to an alteration in transcription. Gibbons make up the “lesser apes” group, the largest group of all the apes. Some of the more pronounced differences include having longer arms, dense hair, and a throat sac used for amplifying sound. The great apes are bonobos, chimpanzees, gorillas, humans, and orangutans. The white-handed gibbon (H. lar), of northern Sumatra and most of the Malay Peninsula northward through Thailand into Yunnan, China, is similar but has white extremities. Knowing that gibbon and orangutan ancestors existed in the same spot together in northern India 13 million years ago, and … The family historically contained one genus, but now is split into four extant genera and 18 species. Lesser Apes, containing the gibbons; Great Apes, containing the orang-utans, gorillas, chimpanzees and humans; Ape features. "Due to a lack of research, we don't know for sure if the small apes; gibbons and siamangs can catch diseases like COVID-19 from humans. [22] The song can be used to identify not only which species of gibbon is singing, but also the area from which it comes. The difference in colour comes about with age; the juveniles are buff and both sexes darken with age, but the male does so much more rapidly. Gorillas are the largest apes. The black crested gibbon (N. concolor) is found from southern China into northernmost Vietnam and Laos; the northern concolor (N. leucogenys), also known as the Chinese white-cheeked gibbon, and southern concolor (N. siki) gibbons are found farther south; and the red-cheeked gibbon (N. gabriellae) lives in southern Vietnam and eastern Cambodia. There are four types of apes like Gorillas, Orang-Utas, Chimpanzees and Gibbons. This structure can become quite large in some species, sometimes equaling the size of the animal's head. Gibbons are small, slender, long-armed, tree-dwelling apes. The whole genome of the gibbons in Southeast Asia was first sequenced in 2014 by the German Primate Center (DPZ) including Christian Roos, Markus Brameier and Lutz Walter along with other international researchers. Retrieved April 7, 2020 from www.sciencedaily.com/releases/2014/09/140910132518.htm. Adult males are black and females are brown, with colour changes similar to those seen in the concolor group. Gibbons differ from great apes in a number of physical ways. Gibbons do not have visible, external tails. You may hear them called the Lesser Apes at times too. "The gibbon in China. [18] However, no records exist of fertile hybrids between different gibbon genera, either in the wild or in captivity. Some species such as the siamang have an enlarged throat sac, which inflates and serves as a resonating chamber when the animals call. This article was most recently revised and updated by, https://www.britannica.com/animal/gibbon-primate, gibbon - Children's Encyclopedia (Ages 8-11), gibbon - Student Encyclopedia (Ages 11 and up). Both sexes have throat sacs and much harsher voices than those of the lar and concolor groups. The males have an upstanding tuft of hair on top of the head and a small inflatable throat sac. Be on the lookout for your Britannica newsletter to get trusted stories delivered right to your inbox. They also differ from great apes in having longer arms, dense hair, and a throat sac used for amplifying sound. The female siamang weighs 10.5 kg (23 pounds) and the male 12 kg (26 pounds); the siamang is the only gibbon with a significant size difference between the sexes. The dental formula is 2.1.2.32.1.2.3 [20] The siamang, which is the largest of the 18 species, is distinguished by having two fingers on each foot stuck together, hence the generic and species names Symphalangus and syndactylus. This is an indication that these major differences in humans and gibbons could have had a common source of plasticity or change. Apes are human’s closest living relatives. The karyotype of gibbons, however, diverged in a much more rapid fashion from the common hominoid ancestor than other apes. [7] The extinct Bunopithecus sericus is a gibbon or gibbon-like ape which, until recently, was thought to be closely related to the hoolock gibbons. Their ball-and-socket wrist joints allow them unmatched speed and accuracy when swinging through trees. Eastern silvery gibbon or central Javan gibbon, This page was last edited on 7 December 2020, at 16:46. They may grow to about 66 inches (170 centimeters) in length and weigh 300 to 600 pounds (135 to 275 kilograms). (that is, the orangutans, gorillas, and chimpanzees) all being placed in a separate family, the Pongidae. The male has a prominent tassel of hair on the front of the lower abdomen. Gibbons are not monkeys. [19], Gibbon skulls and teeth resemble those of the great apes, and their noses are similar to those of all catarrhine primates. This may have led to the development of a suite of physical characteristics, distinct from their great ape relatives, to adapt to their habitat of dense, canopy forest. The large and entirely black siamang is found alongside white- and dark-handed gibbons on the Malay Peninsula and Sumatra. From Chinese cultural influence, the Zen motif of the "gibbon grasping at the reflection of the moon in the water" became popular in Japanese art, as well, though gibbons have never occurred naturally in Japan. More specifically, they are classified as small apes, because (you guessed it) they are smaller than the great apes — gorillas, chimpanzees, bonobos, orangutans and humans. Get exclusive access to content from our 1768 First Edition with your subscription. Monkeys. Let us know if you have suggestions to improve this article (requires login). But disease transmission from and to humans is well-documented in the great apes like gorillas and chimpanzees," she said. Gibbon populations continue to dwindle because of poaching, one of the major threats to these small apes whose bones are commonly used in traditional medicine as ‘monkey bone balm’ or tonic additives. The siamang (S. syndactylus) inhabits the forests of Sumatra and Malaya. Adding up, this implies that at least 52 major chromosomal rearrangements are needed to compare the common hominoid ancestor to today’s gibbons. They are found only in the Indo-Malayan region, extending from India and China, down through mainland Southeast Asia and into Indonesia. Because they are so dextrous while moving in the trees, almost no predators can catch them. Gibbons, like the great apes (gorillas, orangutans, chimpanzees, and bonobos), have a humanlike build and no tail, but gibbons seem to lack higher cognitive abilities and self-awareness. "My Dad's a scientist and he taught me about evolution and that started to really get me fascinated with great apes," she said. A Gibbon is often described as a Monkey but most classify them as Apes. The Taoists ascribed occult properties to gibbons, believing them to be able to live for several hundred years and to turn into humans. Gibbons are small apes.. With 12 species, the gibbons comprise the largestgroup of the apes. Gibbons are among the most endangered apes and among the most critically endangered of all non-human primate species. Their voices are much more powerful than that of any human singer, although they are at best half a human's height. They are the fastest and most agile of all tree-dwelling, nonflying mammals.[4]. The great apes are much more intelligent than monkeys and gibbons. Gibbons were the first apes to diverge from the common ancestor of humans and apes about 16.8 million years ago. Most gibbon species are about 40–65 cm (16–26 inches) in head and body length, but the siamang (Symphalangus syndactylus) can grow up to 90 cm (35 inches). Evol. There are four genera of gibbons. The lars, a group of species classified in the genus Hylobates, are the smallest and have the densest body hair. Gibbons are still widely distributed in the rainforests and monsoon forests of Southeast Asia, but they are more and more under threat as their forest habitat is destroyed. Molecular data indicate that the four groups are as different from one another as chimpanzees are from humans. They feed mainly on fruit, with varying proportions of leaves and with some insects and bird eggs as well as young birds. Also called the lesser apes or small apes, gibbons differ from great apes (chimpanzees, bonobos, gorillas, orangutans and humans) in being smaller, exhibiting low sexual dimorphism, and not making nests. No common specific sequence element in the independent rearrangements was found while 46% of the gibbon-human synteny breakpoints occur in segmental duplication regions. [7], One unique aspect of a gibbon's anatomy is the wrist, which functions something like a ball and socket joint, allowing for biaxial movement. Humans are apes, apes describe several different species including humans(Usually this group are called the Great Apes (Hominidae).

They have a body that is designed for speed and movement. On the ground, gibbons walk erect with the arms held aloft or behind. [7][8] An analysis based on morphology suggests that the four genera are ordered as (Symphalangus, (Nomascus, (Hoolock, Hylobates)))[9], A coalescent-based species tree analysis of genome-scale datasets suggests a phylogeny for the four genera ordered as (Hylobates, (Nomascus, (Hoolock, Symphalangus))). The smallest of the apes, gibbons are often referred to as ‘lesser apes’. The family historically contained one genus, but now is split into four extant genera and 18 species. The hoolock gibbon (Hoolock hoolock) is found from Myanmar west of the Salween River into Assam, India, and Bangladesh. …features; the gibbons are called lesser apes. For other uses, see, Skeat, Walter William (1910), “gibbon”, in. They eat mostly fruit. Gibbon genome sequence deepens understanding of primates rapid chromosomal rearrangements. (1967). [23], Gibbons often retain the same mate for life, although they do not always remain sexually monogamous. Ms Thompson now heads up Perth Zoo's primate section and works with other zoos and communities around the world to save endangered species like the Sumatran orangutan, Javan gibbon and white-cheeked gibbon. The smaller species (both sexes) weigh about 5.5 kg (12 pounds); others, such the concolor gibbon, weigh about 7.5 kg (17 pounds). Matsudaira K, Ishida T (2010) Phylogenetic relationships and divergence dates of the whole mitochondrial genome sequences among three gibbon genera. [29], These crucial findings in genetics have contributed to the use of gibbons as a genetic model for chromosome breakage and fusion, which is a type of translocation mutation. [39], The sinologist Robert van Gulik concluded gibbons were widespread in central and southern China until at least the Song dynasty, and furthermore, based on an analysis of references to primates in Chinese poetry and other literature and their portrayal in Chinese paintings, the Chinese word yuán (猿) referred specifically to gibbons until they were extirpated throughout most of the country due to habitat destruction (circa 14th century). In the concolor group, which is classified in the genus Nomascus, both sexes are black as juveniles, but the females lighten to buff with maturity, so that the two sexes look quite different as adults. [13], Many gibbons are hard to identify based on fur coloration, so are identified either by song or genetics. People more often confuse apes with monkeys but they are totally two different species. Gibbon voices are loud, are musical in tone, and carry over long distances. The very high rate of chromosomal disorder and rearrangements (such as duplications, deletions or inversions of large stretches of DNA) due to the moving of this large DNA segment is one of the key features that are unique to the gibbon genome. These very acrobatic primates live in southeast Asia. Gibbons are slender, long-limbed apes that live in tropical and subtropical forests in Southeast Asia. Gibbons belong to the group of lesser apes. In fact, we shared a common ancestor with gibbons as recently as 16.8 million years ago! The sexes look alike in the silvery gibbon (H. moloch) of Java and in the white-bearded (H. albibarbis) and Müller’s (H. muelleri) gibbons, both from different parts of Borneo. Most gibbons are about 16 to 26 inches (40 to 65 centimeters) long. [35] The Kalaweit Project also has gibbon rehabilitation centers on Borneo and Sumatra. Western silvery gibbon or western Javan gibbon. Instead, they sleep upright on branches, resting on hard pads of skin on their bottoms. Researchers view this unusually high rate of chromosomal rearrangement that is specific in small apes like gibbons could potentially be due to factors that increase the rate of chromosomal breakage or factors that allow derivative chromosomes to be fixated in a homozygous state while mostly lost in other mammals.[28]. Gibbons are arboreal; they spend most of their lives in trees. [34] On the island of Phuket in Thailand, a volunteer-based Gibbon Rehabilitation Center rescues gibbons that were kept in captivity, and are being released back into the wild. [30], Researchers have found a coincidence between major environmental changes in southeast Asia about 5 million years ago that caused a cyclical dynamic of expansions and contractions of their forest habitat; an instance of radiation experienced by the gibbon genera. [17] These morphological ambiguities have led to hybrids in zoos. One of the gibbons that had its genome sequenced is a white-cheeked gibbon (Nomascus leucogenys, NLE) named Asia. By signing up for this email, you are agreeing to news, offers, and information from Encyclopaedia Britannica. Their fur is usually black, gray, or brownish, often with white markings on hands, feet, and face. [8] Whole genome analysis suggests divergence of Hylobates pileatus from Hylobates moloch 1.5-3.0 Mya. [2] An extinct sixth genus, Junzi, was identified in 2018 based on a partial skull found in China. This greatly reduces the amount of energy needed in the upper arm and torso, while also reducing stress on the shoulder joint. They live in forests, and are able to swing from tree to tree at incredible speeds. Mol. They are active during the day and live in small monogamous groups that defend territories in the treetops. Kloss’s gibbon (H. klossii), from the Mentawai Islands west of Sumatra, is completely black throughout its life. Each genus comprises a distinct, well-delineated lineage, but the sequence and timing of divergences among these genera has been hard to resolve, even with whole genome data, due to radiative speciations and extensive incomplete lineage sorting. [36][37], The IUCN Species Survival Commission Primate Specialist Group announced 2015 to be the Year of the Gibbon[38] and initiated events to be held around the world in zoos to promote awareness of the status of gibbons. The primitive opposable anthropoid thumb is reduced as a specialization for this method of locomotion. Lesser apes. The pileated gibbon (H. pileatus), of southeastern Thailand and western Cambodia, has white hands and feet; the male is black and the female buff with a black cap and chest patch. (2014, September 10). Gibbons are apes in the family Hylobatidae (/ˌhaɪləˈbætɪdiː/). Because they are so agile while moving in the trees, almost no predators can catch them. The dark-handed gibbon (H. agilis), which lives on Sumatra south of Lake Toba and on the Malay Peninsula between the Perak and Mudah rivers, may be either tan or black and has white facial markings. [41], This article is about a family of apes. They are part of the ape family and are classified as lesser apes because they are smaller than the great apes. [29], In addition, there are characteristic genes in the gibbon genome which had gone through a positive selection and are suggested to give rise to specific anatomical features for gibbons to adapt to their new environment. The other is COL1A1, which is responsible for the development of collagen, a protein that is directly involved with the forming of connective tissues as well as bone and cartilage development. Gibbons are arboreal and move from branch to branch with speed and great agility by swinging from their arms (brachiating). [26] They are the fastest and most agile of all tree-dwelling, nonflying mammals.[26]. But disease transmission from and to humans is well-documented in the great apes like gorillas and chimpanzees," she said.
