Their voices are much more powerful than that of any human singer, although they are at best half a human's height. Single offspring are born after about seven months’ gestation and take seven years to mature. Reuters. 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. They are part of the ape family and are classified as lesser apes because they are smaller than the great apes. Let us know if you have suggestions to improve this article (requires login). The family historically contained one genus, but now is split into four extant genera and 18 species. Get exclusive access to content from our 1768 First Edition with your subscription. The decrease in gibbon population is also largely due to habitat loss as a result of urban expansion and land conversion, mostly for agriculture. Their fur is usually black, gray, or brownish, often with white markings on hands, feet, and face. [13], Many gibbons are hard to identify based on fur coloration, so are identified either by song or genetics. [7] Adaptive divergence associated with chromosomal rearrangements led to rapid radiation of the four genera 5-7 Mya. How many cervical vertebrae do giraffes have? They are the fastest and most agile of all tree-dwelling, nonflying mammals.[4]. van Gulik, Robert. 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]. The gibbons are also known as the small apes. 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. 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. 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. With 12 species, the gibbons comprise the largestgroup of the apes. There are four types of apes like Gorillas, Orang-Utas, Chimpanzees and Gibbons. The large and entirely black siamang is found alongside white- and dark-handed gibbons on the Malay Peninsula and Sumatra. The various species of gibbons can be divided into four genera: Hoolock, Hylobates, Nomascus, and Symphalangus.

Corrections? 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. 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). This greatly reduces the amount of energy needed in the upper arm and torso, while also reducing stress on the shoulder joint. 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. Both sexes have throat sacs and much harsher voices than those of the lar and concolor groups. 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. 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. No, gibbons are apes. Both sexes have a large throat sac, and their vocal repertoire includes a very harsh shrieking and booming call. 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. [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. Gibbons are referred to as small apes along with their siamang cousins. The animals are best known for their loud, penetrating calls and their ability to swing athletically from one tree branch to another. Gibbon voices are loud, are musical in tone, and carry over long distances. Molecular data indicate that the four groups are as different from one another as chimpanzees are from humans. [8] Whole genome analysis suggests divergence of Hylobates pileatus from Hylobates moloch 1.5-3.0 Mya. The team found that a jumping DNA element named LAVA transposon (also called gibbon-specific retrotransposon) is unique to the gibbon genome apart from humans and the great apes. Gibbons were the first apes to diverge from the common ancestor of humans and apes about 16.8 million years ago. [31] Gibbons, however, not only seemed to be free from problems but let the change help them effectively adapt to their environment. 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. Interspecific hybrids, hybrids within a genus, are also suspected to occur in wild gibbons where their ranges overlap. They also differ from great apes in having longer arms, dense hair, and a throat sac used for amplifying sound. The remaining two groups each contain only one or two species. Great apes, for example, are able to recognize themselves in mirrors (monkeys and other nonhumans cannot, with the exception of bottlenose dolphins). Adult males are black and females are brown, with colour changes similar to those seen in the concolor group. Lesser apes. Gibbons are intelligent and social animals. Planet of the apes: Gibbons are last ape to have genome revealed. 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. Gibbons are arboreal; they spend most of their lives in trees. The English word 'gibbon' is said to be a reborrowing from French, and folk etymology (cf. Gibbons do not have visible, external tails. In most species, males and some females sing solos to attract mates, as well as advertise their territories. These very acrobatic primates live in southeast Asia. [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. Fact #2 – Gibbons mostly move by swinging The smallest apes are the gibbons. 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. Gibbon (surname))[5] originally from an Orang Asli word. 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. Lesser Apes, containing the gibbons; Great Apes, containing the orang-utans, gorillas, chimpanzees and humans; Ape features. [35] The Kalaweit Project also has gibbon rehabilitation centers on Borneo and Sumatra. [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. Zookeepers teach people about gibbons, and how we should be conserving their natural habitat. 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. In addition to extra-pair copulations, pair-bonded gibbons occasionally "divorce. 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? This incorporation of the jumping gene near genes involved in chromosome replication is thought to make the rearrangement in the genome even more likely, leading to a greater diversity within the gibbon genera. Gibbons are small apes comprising 20 species, all of which are endemic to South and Southeast Asia. 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). …features; the gibbons are called lesser apes. 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. [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. 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). 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. Gorillas are the largest apes. Family Hominidae (great apes and humans) 4 genera, 7 African and Eurasian species until human expansion since the Late Pleistocene.…, …is an adaptation seen in gibbons. [29] This gene is thought to have a role in gibbons having stronger muscles.

They have a body that is designed for speed and movement. The primitive opposable anthropoid thumb is reduced as a specialization for this method of locomotion. Gibbons also have long hands and feet, with a deep cleft between the first and second digits of their hands. (1967). [18] However, no records exist of fertile hybrids between different gibbon genera, either in the wild or in captivity. But disease transmission from and to humans is well-documented in the great apes like gorillas and chimpanzees," she said. They eat mostly fruit. [26] They are the fastest and most agile of all tree-dwelling, nonflying mammals.[26]. Gibbons belong to the group of lesser apes. The family historically contained one genus, but now is split into four extant genera and 18 species. They are smaller than Apes and they don’t have the size differences. The great apes include gorillas, chimpanzees, orangutans, and bonobos. The great apes are bonobos, chimpanzees, gorillas, humans, and orangutans. Gibbons (/ˈɡɪbənz/) are apes in the family Hylobatidae (/ˌhaɪləˈbætɪdiː/). The non-human types of apes are divided into two groups: great apes — gorillas, bonobos, chimpanzees and orangutans — and lesser apes — gibbons and siamangs. 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. An essay in Chinese animal lore." No common specific sequence element in the independent rearrangements was found while 46% of the gibbon-human synteny breakpoints occur in segmental duplication regions. Corrections? The male has a prominent tassel of hair on the front of the lower abdomen. 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. [21], Like all primates, gibbons are social animals. Eastern silvery gibbon or central Javan gibbon, This page was last edited on 7 December 2020, at 16:46. By signing up for this email, you are agreeing to news, offers, and information from Encyclopaedia Britannica. Gibbons differ from great apes in a number of physical ways. [22] The song can be used to identify not only which species of gibbon is singing, but also the area from which it comes. Western Hoolock gibbons, also known as white-browed gibbons, are the only apes that live in the Indian sub-continent. Baylor College of Medicine. Mol. [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))). Western silvery gibbon or western Javan gibbon. For other uses, see, Skeat, Walter William (1910), “gibbon”, in. 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. 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. Gibbons are the small apes that are grouped in the family Hylobatidae.The family is divided into four genera based on their diploid chromosome number: Hylobates (44), Hoolock (38), Nomascus (52), and Symphalangus (50). 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. They can also make leaps up to 8 m (26 ft), and walk bipedally with their arms raised for balance. Articles from Britannica Encyclopedias for elementary and high school students. [2], The family is divided into four genera based on their diploid chromosome number: Hylobates (44), Hoolock (38), Nomascus (52), and Symphalangus (50). They may grow to about 66 inches (170 centimeters) in length and weigh 300 to 600 pounds (135 to 275 kilograms).
