from Animal Diversity Web Hylobatidae gibbons and siamangs This family contains 1 genus, Hylobates, and approximately 11 species (some authorities recognize a second genus, Symphalangus) . They are found only in the tropical forests of southeastern Asia, including on Sumatra, Borneo, Java, and other islands as well as the mainland. These apes are of medium size (3.9-12.7 kg). They lack tails. Their forearms are remarkably long, and both forefeet and hindfeet are long and thin. The forefeet have a deep cleft between first and second digits. The pelage of these apes is usually black, gray, or brownish, often with white markings on hands, feet, and facial region. Ischial callosities are present. Some gibbons and siamangs have an enlarged throat sac, which inflates and serves as a resonating chamber when the animals call. This structure is enormous in a few species, equalling the size of the animal's head. The skulls of hylobatids resemble those of hominids, with very short rostra, enlarged braincases, and large orbits that face forward. Hylobatds are catarrhine primates; that is, their nostrils are close together and face forward and slightly downward. They lack cheek pouches and their stomach is not sacculated. Their teeth are similar to those of hominids. The molars are bunodont and lack lophs. The upper molars usually have a cingulum, which is sometimes large. The canines are prominent (more so than in most hominids) but not sexually dimorphic. The dental formula is 2/2, 1/1, 2/2, 3/3 = 32.

Most have grasping hands, flat nails (instead of claws), and a large brain. Primate mothers carry their young on their bodies until they are weaned; the ties between mother and baby are very strong. There are about 200 species of primates, including monkeys, lemurs, chimps, humans, and others. Primates are divided into three groups: Tree shrews Tupaiidae: Tree shrews Prosimians Cheirogaleidae: Dwarf lemurs Lemuridae: Large lemurs Megaladapidae: Sportive lemurs Indridae: Leaping lemurs Daubentoniidae: Aye-Aye Loridae: Lorises and galagos Tarsiidae: Tarsiers Anthropoids Callitrichidae: Marmosets and tamarins Cebidae: New World Monkeys (like the Howler monkey Cercopithecidae: Old World monkeys (like the mandrill Hylobatidae: Lesser Apes (Gibbons and siamangs) Hominidae: Great Apes (like gorillas, chimps, and orangutans) and humans

68. About Gibbons Gibbons are one of the few monogamous primates, and whether on the ground or inthe trees, they are known for their dexterity and ability to walk upright. http://www.gibboncenter.org/about_gibbons.htm

Gibbon Conserv a tion Center (formerly International Center for Gibbon Studies) A nonprofit center for the study, preservation, and propagation of highly endangered species About Gibbons photo by J. Zuckerman Hylobates moloch Gibbons are classified in the Kingdom Animalia Phylum Chordata , Subphylum Vertebrata , Class Mammalia , Order Primates , and Family Hylobatidae Gibbons are small, arboreal apes distributed in the wild in the tropical and subtropical rainforests of Southeast Asia. They are currently found in small populations in China, Laos, Vietnam, Cambodia, Thailand, Bangladesh, NE India, Myanmar, Malaysia, and Indonesia. Most countries consider them to be endangered, and they are threatened primarily by loss of their forest habitat. Other factors contributing to their demise include the illegal wildlife trade, the use of their body parts in the manufacture of traditional medicines, and poaching. photo by A. Mootnick Nomascus l. leucogenys Gibbons have long fascinated scientists and lay people because of their agility in the forest tree tops. Gibbons are excellent brachiators (arm-swingers), and this is one reason they make popular zoo exhibits. In the wild, gibbons live in nuclear families consisting of a mated pair and their dependent offspring. The family unit occupies a territory, and they defend its boundaries by a vigorous vocal and visual display. The vocal display consists of a spectacular, bird-like duet between the mated pair, with the young occasionally joining in. This vocalization, or song, is audible for long distances and is the primary way scientists (and poachers) locate wild populations. This haunting melody has become

Gibbons Gibbons are found only in southeast Asia. They live in rain forests, and are usually found in the canopy of the trees. However, they have been observed on the ground and in the highest branches of the trees. The Gibbon dental formula is 2:1:2:3. They eat leaves, fruit, insects and bird eggs. Proportions of arms and legs illustrate the specialization for brachiation. Shoulder joints also allow for flexible rotation of the shoulders and arms. A short body and legs make gibbons relatively light weight. Gibbons are true brachiators. That means they are able to arm swing through the trees. They also climb and leap. On the ground they walk bipedally with their arms held out to their sides. Their forearms are much longer than their hindlimb. When upright, Gibbons stand more erect than any other primate except for man. Gibbons live in male-female pairs (pair bonds), that will include children. Lone indivduals are either old, or young animals attempting to leave the nest and start their own family. Gibbons show no signs of sexual dimorphism that is common in many other primates. This is due to the relationships they form socially that pair males and females for life. Gibbons will sign songs to each other to help maintain this bonded relationship...gibbons frown on divorce in otherwords and want to know where each other is when they are separated!

71. Untitled Document Nonhuman primates that are monogamous tend to mate for life and are usually highlyterritorial. Gibbons and Indris are both typical of monogamous primates. http://www.mc.maricopa.edu/~reffland/anthropology/anthro2003/origins/primates/or

"Social organization" "Social organization" tends to be all-encompassing and a rather vague concept. Social organizations among primates vary primarily on the basis of the following factors: 1. Group Size 2. Group Composition 3. Mating Systems 4. Social Roles - especially for adult females and males 5. Various Types of Dominance 6. Permanence versus Instability of Group Membership 7. Tendency to Aggregate into Larger Social Groups 8. Presence of only Heterosexual Reproductive Units, All-Male Groups or All-Female Groups, or Single Individuals 9. Patterns of Interactions. The best way to examine primate societies may be to divide them into groups based on: (A) large troops, medium-size groups, and small units, or (B) multi-female and multi-male; uni-male and multi-female; uni-male and uni-female, or (C) multiple mating by males and females, polygynous, and monogamous. Several trends can be noted if we look at these possible ways to group primate societies. First, monogamous groups are small, normally containing only one fully adult female and one fully adult male and their offspring. Gibbons fit this model well. Second, a system of multiple matings by both females and males or multi-females are usually the largest of primate societies. Some groups can reach 300 individuals in these cases. Third, polygynous groups contain one adult male and several adult females and off-spring and are moderate in size. Gorilla troops fit this profile. Keep in mind that polygynous groups such as this, also called harems, maximize reproduction by keeping a pool of receptive females available. It is also true that the greatest sexual dimorphism - difference in size between males and females - occur in polygynous societies.

Supplemental Lecture (97/05/04 update) by Stephen T. Abedon abedon.1@osu.edu Chapter title : Descent of Man A list of vocabulary words is found toward the end of this document Homo sapiens did not appear on the earth, just a geologic second ago, because evolutionary theory predicts such an outcome based on themes of progress and increasing neural complexity. Humans arose, rather, as a fortuitous and contingent outcome of thousands of linked events, any one of which could have occurred differently and sent history on an alternative pathway that would not have led to consciousness. To cite just four among a multitude: If our inconspicuous and fragile lineage had not been among the few survivors of the initial radiation of multicellular animal life in the Cambrian explosion 530 million years ago, then no vertebrates would have inhabited the earth at all. If a small and unpromising group of lobe-finned fishes had not evolved fin bones with a strong central axis capable of bearing weight on land, then vertebrates might never have become terrestrial. If a large extraterrestrial body had not struck the earth 65 million years ago, then dinosaurs would still be dominant and mammals insignificant (the situation that had prevailed for 100 million years previously).

Modern classification has its roots in the system of Carolus Linnaeus, who grouped species according to shared physical characteristics. These groupings have been revised since Linnaeus to improve consistency with the Darwinian principle of common descent. Molecular systematics, which uses Genomic DNA analysis has driven many recent revisions and is likely to continue to do so. Scientific classification belongs to the science of taxonomy or biological systematics. Click the link for more information. Kingdom: Animalia Animals are the group of organisms that constitute the kingdom Animalia. Typically, they are multicellular in composition and capable of both locomotion and responding to their surroundings. Unlike plants, animals do not photosynthesize, instead consuming plants or other organisms to grow and sustain themselves. Most animals have a body plan that becomes fixed as they mature and, except in animals that metamorphose, is established early in their development from embryos. The scientific study of animals is called zoology. Click the link for more information.

Apes A pes and humans differ from all of the other primates in that they lack external tails . They also are more intelligent and more dependent for survival on learned behavior patterns. This is especially true of the great apes and people. A ll of the apes and humans are members of the same superfamily, the Hominoidea . Within the Hominoidea, genetic comparisons indicate that there are probably three families of apes and one of humans.

Large View More 1 More 2 Primates an order of the vertebrate class Mammalia that includes man, the apes, monkeys, lorises, and lemurs. Carolus Linnaeus used the name, meaning 'chiefs', in 1758. The majority of primates are adapted for life in trees, but many are ground dwelling. Some principally feed on leaves, fruits and different vegetable matter, while others are insectivorous; many eat fruits and leaves but also hunt live prey. Primates range in size from about 30 cm in marmosets, weighing less than a kilogram, to gorillas, which stand almost 200 cm high, and may weigh as much as 350 kg. Hylobates hoolock ), is found in the forests of Sylhet, Chittagong, and the Chittagong Hill Tracts. This species is also found in Assam in India. Of the 180 or so known species of recent primates, 25 are found in South Asia. Bangladesh has 10 species in 4 families. Some of them are threatened. Slow Loris Nycticebus coucang A member of the family Loridae. Face resembles that of lemur. Body dark ashy-grey or grey-brown with a darker band down the middle of the back; beneath lighter grey. Eyes owl-like, circled with dark patches. Head rounded, ear and tail very small. Head-body length 26-40 cm; bulky, weight 1000-1600 g; generally solitary, nocturnal and arboreal. Movements slow, climbs readily with firm grips. Spends days curled in tree hollows. Feeds on leaves and shoots of trees, fruits, insects, bird eggs and young birds. A single young is born after a gestation period of c. 3 months. Occurs in the mixed evergreen forests of the country and also in deciduous forests of northern hilly areas.
