The family Ursidae is one of nine families in the suborder Caniformia, or "doglike" carnivorans, within the order Carnivora. The preferred parts to eat are the brain and eggs. [153], Bears, like other animals, may symbolize nations. The brown bear can live an average of 25 years. [65] In autumn, some bear species forage large amounts of naturally fermented fruits, which affects their behavior. For the American Black Bear this is no different, the ancestors of an American black bear group with the ancestors of an Asiatic black bear. Another early bear in the lineage leading to grizzlies is Ursus minimus of the cave line bears, which lived in the Pliocene era, about 10 mya. [40] The smallest species is the sun bear, which ranges 25–65 kg (55–145 lb) in weight and 100–140 cm (40–55 in) in length. [67] Such masts can be very important to the diets of these species, and mast failures may result in long-range movements by bears looking for alternative food sources. [44] Considerable variation occurs in dental formula even within a given species. The canine teeth are large but mostly used for display, and the molar teeth flat and crushing. [11], The family Ursidae is one of nine families in the suborder Caniformia, or "doglike" carnivorans, within the order Carnivora. People are cutting down trees leaving the bears with no benefits towards getting larger New York and 1 other state had the highest population of Bears families in 1840. Warning sounds include jaw-clicking and lip-popping, while teeth-chatters, bellows, growls, roars and pulsing sounds are made in aggressive encounters. [65] The panda's diet is over 99% bamboo,[69] of 30 different species. Bears however have a single type of melanin and the hairs have a single color throughout their length, apart from the tip which is sometimes a different shade. Ursavinae [96] In northern living species, birth takes place during winter dormancy. [64][77][76] These animals may be taken by a short rush and ambush, though hiding young may be stiffed out and pounced on. As a family, bears are thought to have evolved some 4.6 million years ago, with the oldest Polar Bear fossil being between 110 and 130 thousand years old. [91], The mating system of bears has variously been described as a form of polygyny, promiscuity and serial monogamy. [26], The New World short-faced bears (Tremarctinae) differentiated from Ursinae following a dispersal event into North America during the mid-Miocene (about 13 Mya). [15] European genera morphologically very similar to Allocyon, and to the much younger American Kolponomos (about 18 Mya),[16] are known from the Oligocene, including Amphicticeps and Amphicynodon. At certain times of the year, these insects can make up 90% of their diets. This form is conventionally said to be related to a Proto-Indo-European word for "brown", so that "bear" would mean "the brown one". After beginning to branch off, the polar bear's ancestors went through. Two lineages evolved from U. minimus: the black bears (including the sun bear, the Asian black bear, and the American black bear); and the brown bears (which includes the polar bear). [54] For example, Asiatic black bears in Taiwan consume large numbers of acorns when these are most common, and switch to ungulates at other times of the year. However, the same DNA fingerprint is absent from other species of brown bear alive today. 450-1100)-language text, Articles containing Swedish-language text, Creative Commons Attribution-ShareAlike License, Images of a few members of the family Ursidae (clockwise from top right) consisting of the, Black Bear Conservation Coalition, for the North American black bear, Polar Bears International, for the polar bear, Bornean Sun Bear Conservation Centre, for the sun bear, Andean Bear Conservation Project, for the Andean bear, Chengdu Research Base of Giant Panda Breeding, for the giant panda, This page was last edited on 6 January 2021, at 14:57. [8], Bear taxon names such as Ursidae and Ursus come from Latin Ursus/Ursa, he-bear/she-bear. Alexander_Saravia Animal Evolution Project Period 3 The Environmental Pressures The Environmental Impacts Currently, people are destroying the bears' habitat because of trees and overfishing. As far as paleontologists can tell, the very first carnivorous mammals evolved during the late Cretaceous period, about 75 million years ago (the half-pound Cimolestes, which lived high up in trees, is the most likely candidate). [70][71] Bromeliads can make up to 50% of the diet of the spectacled bear, which also has strong jaws to bite them open. Courtship may be brief, although in some Asian species, courting pairs may engage in wrestling, hugging, mock fighting and vocalizing. (2014):[35], The second alternative phylogenetic hypothesis was implemented by McKenna et al. [143], Bears are popular in children's stories, including Winnie the Pooh,[144] Paddington Bear,[145] Gentle Ben[146] and "The Brown Bear of Norway". Older pre-ice-age brown bears, dating to between 43,000 and 38,000 years ago, had a different genetic signature matching that of modern bears from eastern Europe. [32][33][34][35] Below is a cladogram of the subfamilies of bears after McLellan and Reiner (1992)[32] and Qiu et al. Yet the two appear to mate successfully whenever they come into contact. This may indicate bears are still in the process of evolving from a mainly meat-eating diet to a predominantly herbivorous one. Tremarctinae [1][2] However, Ringe notes that while this etymology is semantically plausible, a word meaning "brown" of this form cannot be found in Proto-Indo-European. Species of Ursavus subsequently entered North America, together with Amphicynodon and Cephalogale, during the early Miocene (21–18 Mya). Polar bears may have moved into what is now Ireland when the region was experiencing much cooler temperatures than it is today. [54] Berries may be foraged in bushes or at the tops of trees, and bears try to maximize the number of berries consumed versus foliage. [134] It is possible that bear worship existed in early Chinese and Ainu cultures. The shaggy coat helps maintain body heat during winter hibernation and is shed in the spring leaving a shorter summer coat. [68] Brown bears, with their powerful digging abilities, commonly eat roots. Bears' non-retractable claws are used for digging, climbing, tearing, and catching prey. [55][58] Bears may dig their dens in hillsides or use caves, hollow logs and dense vegetation for shelter. [130], Bears have been popular subjects in art, literature, folklore and mythology. The cave line bears persisted until th… Cubs may squeal, bawl, bleat or scream when in distress and make motor-like humming when comfortable or nursing. [140], The constellations of Ursa Major and Ursa Minor, the great and little bears, are named for their supposed resemblance to bears, from the time of Ptolemy. Polar and brown bears are hugely different in terms of body size, skin and coat colour, fur type, tooth structure and many other physical features. [47], Bears have small rounded ears so as to minimize heat loss, but neither their hearing or sight are particularly acute. [79][76] Large mammalian prey is typically killed by a bite to the head or neck, or (in the case of young) simply pinned down and mauled. and others. The protozoan Toxoplasma gondii has been found in polar bears, and the nematode Trichinella nativa can cause a serious infection and decline in older polar bears. [41] Prehistoric North and South American short-faced bears were the largest species known to have lived. Bark may be spread around to draw attention to the marking post. Texture remains very firm, a good storing apple. This maternal lineage is now present in all modern polar bears.". [36] Below is the cladogram based on McKenna and Bell (1997) classification:[36], The phylogeny of extant bear species is shown in a cladogram based on complete mitochondrial DNA sequences from Yu et al. After she decided to return home to Leelanau County, she became Michigan's first woman to be legally elected and serve as county prosecutor in 1936. [44], Bears are generally bulky and robust animals with short tails. Modern polar bears are partly descended from extinct brown bears that lived in Ireland during the last ice age, scientists have discovered, Polar bears have mitochondrial DNA found in the bones of ice age bears discovered in caves in Ireland. [133], There is evidence of prehistoric bear worship, though this is disputed by archaeologists. [36] Amphicynodontinae under this classification were classified as stem-pinnipeds in the superfamily Phocoidea. Ancestors of Lille Foster Generation No. [50], Bears have a fairly simple digestive system typical for carnivorans, with a single stomach, short undifferentiated intestines and no cecum. Polar bears have hollow, translucent guard hairs which gain heat from the sun and conduct it to the dark-colored skin below. [26] They invaded South America (≈2.5 or 1.2 Ma) following formation of the Isthmus of Panama. [142] Ursa Major has been associated with a bear for as much as 13,000 years since Paleolithic times, in the widespread Cosmic Hunt myths. [15] The subfamily includes the younger genera Phoberocyon (20–15 Mya), and Plithocyon (15–7 Mya). Members of the living lineages of bears diverged from Ursavus between 15 and 20 Mya,[24][25] likely via the species Ursavus elmensis. Ailuropodinae [44], Most bears are opportunistic omnivores and consume more plant than animal matter. The Arctotherium angustidens was isolated primarily to South America during the Pleistocene epoch 2.5 million to 11,000 years ago. [30], The bears form a clade within the Carnivora. [95] Giant pandas may give birth to twins but they can only suckle one young and the other is left to die. The Polar Bear is a member of the Ursidae family and shares a common ancestor with the black and brown bear. [74] Sun bears use their long tongues to lick up both insects and honey. Climate change is believed to have produced mating opportunities for the two species at various times in the past 100,000 years. Male Alaskan brown bears and polar bears may continue to grow until they are 11 years old. Babies spend the first two years of their lives clinging to their mothers’ backs. Ursinae. of the Asiatic black bear and the American black bear, had the opportunity to meet and to mate. This animal is known to have existed sometime during the late Oligocene period, some 27 million years ago. [118] Support for bear protection is widespread, at least in more affluent societies. They use olfaction to locate other foods, encounter mates, avoid rivals and recognize their cubs. Ptolemy named the constellations in Greek: CS1 maint: multiple names: authors list (, International Union for Conservation of Nature, "Hooking Up and Using the John: Why Do We Use So Many Euphemisms? [13], The bear family includes the most massive extant terrestrial members of the order Carnivora. [52][81] For hibernating species, weight gain is important as it provides nourishment during winter dormancy. Despite their heavy build and awkward gait, they are adept runners, climbers, and swimmers. The most Bears families were found in the USA in 1880. The strong forelimbs are used to catch prey, to excavate dens, to dig out burrowing animals, to turn over rocks and logs to locate prey, and to club large creatures. [98] Cubs may flee and the mother defends them even at the cost of her life. All the remaining species of bear are Asian. They eat anything from leaves, roots, and berries to insects, carrion, fresh meat, and fish, and have digestive systems and teeth adapted to such a diet. [97] Males kill young to bring the female into estrus. [61][62] Fights between males can occur and older individuals may have extensive scarring, which suggests that maintaining dominance can be intense. [131] In many Native American cultures, the bear is a symbol of rebirth because of its hibernation and re-emergence. Although only eight species of bears are extant, they are widespread, appearing in a wide variety of habitats throughout the Northern Hemisphere and partially in the Southern Hemisphere. [115] The IUCN lists six bear species as vulnerable;[116] even the two least concern species, the brown bear and the American black bear,[116] are at risk of extirpation in certain areas. [31], There are two phylogenetic hypotheses on the relationships among extant and fossil bear species. This was about 21% of all the recorded Bears's in the USA. Genetic evidence shows they are descended from Irish brown bears that lived during the last ice age. [44] A fecal plug is formed in the colon, and is expelled when the bear wakes in the spring. Hemicyoninae [92][93][94] During the breeding season, males take notice of females in their vicinity and females become more tolerant of males. [26] The sloth bear is a modern survivor of one of the earliest lineages to diverge during this radiation event (5.3 Mya); it took on its peculiar morphology, related to its diet of termites and ants, no later than by the early Pleistocene. It is surprising, then, to discover that one of the ancestors of these creatures was seven metres long and lived a full and active life on the ground. Then, it was reported to be near a dumpster by the PNC bank and finally at a dumpster behind Ulta Beauty. [57], The most widespread species is the brown bear, which occurs from Western Europe eastwards through Asia to the western areas of North America. Polar bears appear to have secondarily re-evolved carnassial-like cheek teeth, as their diets have switched back towards carnivory. [48] Sloth bears lack lower central incisors and use their protusible lips for sucking up the termites on which they feed. [119] The giant panda has become a worldwide symbol of conservation. They distribute their weight toward the hind feet, which makes them look lumbering when they walk. In general these two species inhabit remote areas with little interaction with humans, and the main non-natural causes of mortality are hunting, trapping, road-kill and depredation. [120] Where bears raid crops or attack livestock, they may come into conflict with humans. "Today's warming climate is again bringing modern polar bears into contact with brown bears in places like Canada and Alaska." [44] The structure of the larynx of bears appears to be the most basal of the caniforms. The American black bear is restricted to North America, and the polar bear is restricted to the Arctic Sea. [52][54] Hence, in more northern temperate areas, browsing and grazing is more common early in spring and later becomes more restricted. [12] Modern bears comprise eight species in three subfamilies: Ailuropodinae (monotypic with the giant panda), Tremarctinae (monotypic with the spectacled bear), and Ursinae (containing six species divided into one to three genera, depending on the authority). Public perception of bears is often positive, as people identify with bears due to their omnivorous diets, their ability to stand on two legs, and their symbolic importance. [95][58] Male bears play no role in raising young. Nuclear chromosome analysis show that the karyotypeof the six ursine bea… [20][21][22][18][23][19], The raccoon-sized, dog-like Cephalogale is the oldest-known member of the subfamily Hemicyoninae, which first appeared during the middle Oligocene in Eurasia about 30 Mya. [17][18][19] In addition to the support of the pinniped–amphicynodontine clade, other morphological and some molecular evidence supports bears being the closet living relatives to pinnipeds. [135] The prehistoric Finns,[136] Siberian peoples[137] and more recently Koreans considered the bear as the spirit of their forefathers. [138] Artio (Dea Artio in the Gallo-Roman religion) was a Celtic bear goddess. Amphicynodontinae Sweet and tart at the same time. The only times bears are encountered in groups are mothers with young or occasional seasonal bounties of rich food (such as salmon runs). With the exception of courting individuals and mothers with their young, bears are typically solitary animals. Nuclear chromosome analysis show that the karyotype of the six ursine bears is nearly identical, with each having 74 chromosomes (see Ursid hybrid), whereas the giant panda has 42 chromosomes and the spectacled bear 52. Based on genetic and morphological data, the Ailuropodinae (pandas) were the first to diverge from other living bears about 19 Mya, although no fossils of this group have been found before about 5 Mya. More than 12,000 bears are thought to be kept on farms in China, Vietnam, and South Korea for the production of bile. [53] Bears must spend much of their time feeding in order to gain enough nutrition from foliage. [95] Lifespan may also vary between species. (Image: © Art by Charlène Letenneur (MNHN) and Pascale Golinvaux (RBINS)) Lions, … [55] At the extremes are the almost entirely herbivorous giant panda and the mostly carnivorous polar bear. The English word "bear" comes from Old English bera and belongs to a family of names for the bear in Germanic languages, such as Swedish björn, also used as a first name. (1997) is to classify all the bear species into the superfamily Ursoidea, with Hemicyoninae and Agriotheriinae being classified in the family "Hemicyonidae". Known for its white flesh and excellent flavor. The carnivore ancestor Dormaalocyon latouri, roamed Europe 56 million years ago. [103][104] During hibernation, the bear's metabolism slows down, its body temperature decreases slightly, and its heart rate slows from a normal value of 55 to just 9 beats per minute. [90] Polar bears leave behind their scent in their tracks which allow individuals to keep track of one another in the vast Arctic wilderness. [13], The earliest members of Ursidae belong to the extinct subfamily Amphicynodontinae, including Parictis (late Eocene to early middle Miocene, 38–18 Mya) and the slightly younger Allocyon (early Oligocene, 34–30 Mya), both from North America. The panda, in particular, spends 12–15 hours a day feeding. Their meat is dark and stringy, like a tough cut of beef. The IUCN lists six bear species as vulnerable or endangered, and even least concern species, such as the brown bear, are at risk of extirpation in certain countries. Cubs are born blind and helpless with at most a thin layer of hair, relying on their mother for warmth.

Her name is derived from the Celtic word for "bear", artos. 1.8-0.01 million years ago Sloth bears- floppy eared Indian relatives of the Brown bear … The Bears family name was found in the USA, the UK, Canada, and Scotland between 1840 and 1920. The chest markings of some species may add to this intimidating display. Dominance between bears is asserted by making a frontal orientation, showing the canine teeth, muzzle twisting and neck stretching. [150][151] The Care Bears began as greeting cards in 1982, and were featured as toys, on clothing and in film. The earliest bear is known as the Ursavus (Dawn Bear). They are classified as caniforms, or doglike carnivorans. Only the ice age brown bears carried the maternal genetic hallmark of polar bears. THE EVOLUTION OF BEAR SPECIES Where did the bear really come from? [42][43] Body weight varies throughout the year in bears of temperate and arctic climates, as they build up fat reserves in the summer and autumn and lose weight during the winter. [65][78] The polar bear mainly preys on seals, stalking them from the ice or breaking into their dens. [28][29] The polar bear is the most recently evolved species and descended from a population of brown bears that became isolated in northern latitudes by glaciation 400,000 years ago. Of these, D. mansonoides and adult C. aerophila were causing pathological symptoms. Older pre-ice-age brown bears, dating to between 43,000 and 38,000 years ago, had a different genetic signature matching that of modern bears from eastern Europe. [55] They occur in a range of habitats which include tropical lowland rainforest, both coniferous and broadleaf forests, prairies, steppes, montane grassland, alpine scree slopes, Arctic tundra and in the case of the polar bear, ice floes. Recent findings suggest that polar bears evolved from a common ancestor of the brown bear between 350,000-6 million. Whatever its origins, the dog was the first animal to be domesticated by early humans. [9][10] The Old English name Beowulf is a kenning, "bee-wolf", for bear, in turn meaning a brave warrior. [4][5] According to author Ralph Keyes, this is the oldest known euphemism. Injuries caused by bears are rare, but are widely reported. [8] The female first name "Ursula", originally derived from a Christian saint's name, means "little she-bear" (diminutive of Latin ursa). Modern bears comprise eight species in three subfamilies: Ailuropodinae (monotypic with the giant panda), Tremarctinae (monotypic with the spectacled bear), and Ursinae (containing six species divided into one to three genera, depending on the authority). A Cephalogale-like species gave rise to the genus Ursavus during the early Oligocene (30–28 Mya); this genus proliferated into many species in Asia and is ancestral to all living bears.
