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. The gibbons are also known as the small apes. There are about twelve species (kinds) of gibbon, making them the largest group in the ape... Habitat and distribution (where they are found). They also differ from great apes in having longer arms, dense hair, and a throat sac used for amplifying sound. 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. Gibbons' diets are about 60% fruit-based,[27] but they also consume twigs, leaves, insects, flowers, and occasionally bird eggs. E. J. Brill, Leiden, Holland. The males have an upstanding tuft of hair on top of the head and a small inflatable throat sac. The current conservation status of gibbon species is alarming - all but one is listed as either Endangered or Critically Endangered. The original meaning of the term referred to only humans and their closest relatives—what is now the modern meaning of the term "hominin". Single offspring are born after about seven months’ gestation and take seven years to mature. There are four types of apes like Gorillas, Orang-Utas, Chimpanzees and Gibbons. To reach the common gibbon ancestor’s karyotype from today’s various living species of gibbons, it will require up to 28 additional rearrangements. 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). The family historically contained one genus, but now is split into four extant genera and 18 species. There are four genera of gibbons. There are two extant branches of the superfamily Hominoidea: the gibbons, or lesser apes; and the hominids, or great apes. Gibbons and Siamangs live in Asia. Gibbons are monogamous (a rare trait among primates) and live in family groups consisting of an adult pair and their young offspring. [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). Gibbons are small apes comprising 20 species, all of which are endemic to South and Southeast Asia. Gorillas are the largest apes. Mol. Gibbons do not have visible, external tails. 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. Adding up, this implies that at least 52 major chromosomal rearrangements are needed to compare the common hominoid ancestor to today’s gibbons. They can also make leaps up to 8 m (26 ft), and walk bipedally with their arms raised for balance. 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. 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. A Gibbon is often described as a Monkey but most classify them as Apes. Gibbons are rare, small, slender, long-armed, tree-dwelling apes. Their primary mode of locomotion, brachiation, involves swinging from branch to branch for distances up to 15 m (50 ft), at speeds as high as 55 km/h (34 mph). 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. van Gulik, Robert. Retrieved April 7, 2020 from www.sciencedaily.com/releases/2014/09/140910132518.htm. The meaning of the taxon Hominidae changed gradually, leading to a modern usage of "hominid" that includes all the great apes including humans. They are active during the day and live in small monogamous groups that defend territories in the treetops. These fascinating apes are monogamous and mate for life. [26] They are the fastest and most agile of all tree-dwelling, nonflying mammals.[26]. Because they are so dextrous while moving in the trees, almost no predators can catch them. They are found only in the Indo-Malayan region, extending from India and China, down through mainland Southeast Asia and into Indonesia. The Taoists ascribed occult properties to gibbons, believing them to be able to live for several hundred years and to turn into humans. [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. Matsudaira K, Ishida T (2010) Phylogenetic relationships and divergence dates of the whole mitochondrial genome sequences among three gibbon genera. But disease transmission from and to humans is well-documented in the great apes like gorillas and chimpanzees," she said. [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. The great apes include gorillas, chimpanzees, orangutans, and bonobos. They eat mostly fruit. This is an indication that these major differences in humans and gibbons could have had a common source of plasticity or change. 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). [35] The Kalaweit Project also has gibbon rehabilitation centers on Borneo and Sumatra. Because they are so agile while moving in the trees, almost no predators can catch them. Planet of the apes: Gibbons are last ape to have genome revealed. 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. There are two main groups of apes, the Great Apes and the Lesser Apes. People more often confuse apes with monkeys but they are totally two different species. Let us know if you have suggestions to improve this article (requires login). Great apes, for example, are able to recognize themselves in mirrors (monkeys and other nonhumans cannot, with the exception of bottlenose dolphins). Unlike great apes, gibbons do not build nests. The non-human types of apes are divided into two groups: great apes — gorillas, bonobos, chimpanzees and orangutans — and lesser apes — gibbons and siamangs. 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. Gibbons are among the most endangered apes and among the most critically endangered of all non-human primate species. [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. ScienceDaily. Monkeys. Test your knowledge of mammals by taking this quiz. One of the gibbons that had its genome sequenced is a white-cheeked gibbon (Nomascus leucogenys, NLE) named Asia. 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. Gibbons are also known as lesser apes, because they are very different from great apes such as gorillas and chimpanzees.
