Their meat is dark and stringy, like a tough cut of beef. Only the ice age brown bears carried the maternal genetic hallmark of polar bears. The panda, in particular, spends 12–15 hours a day feeding. [44] The general dental formula for living bears is: [27] Their earliest fossil representative is Plionarctos in North America (c. 10–2 Ma). Empire. [44] The structure of the larynx of bears appears to be the most basal of the caniforms. Since the invention of firearms, people have been able to kill bears with greater ease. [15] The subfamily includes the younger genera Phoberocyon (20–15 Mya), and Plithocyon (15–7 Mya). Possible ancestors of the black bear include the extinct Ursus abstrusus and Ursus vitabilis. The family Ursidae is one of nine families in the suborder Caniformia, or "doglike" carnivorans, within the order Carnivora. They primarily eat the highly digestible blubber. [60] Bears are overwhelmingly solitary and are considered to be the most asocial of all the Carnivora. 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. [149] The Hanna-Barbera character Yogi Bear has appeared in numerous comic books, animated television shows and films. There were five bear-baiting gardens in Southwark, London at that time; archaeological remains of three of these have survived. The creature ate a similar diet to modern giant pandas, suggesting … Also used in baking. Bears are found on the continents of North America, South America, Europe, and Asia. [64][77][76] These animals may be taken by a short rush and ambush, though hiding young may be stiffed out and pounced on. Externally they have ticks, fleas and lice. New York and 1 other state had the highest population of Bears families in 1840. [44] A fecal plug is formed in the colon, and is expelled when the bear wakes in the spring. Nuclear chromosome analysis show that the karyotypeof the six ursine bea… This maternal lineage is now present in all modern polar bears.".

[44], Most mammals have agouti hair, with each individual hair shaft having bands of color corresponding to two different types of melanin pigment. [3] This terminology for the animal originated as a taboo avoidance term: proto-Germanic tribes replaced their original word for bear—arkto—with this euphemistic expression out of fear that speaking the animal's true name might cause it to appear. [44], Bears are generally bulky and robust animals with short tails. They have been trained to dance,[125] and were kept for baiting in Europe at least since the 16th century. [14] It is unclear whether late-Eocene ursids were also present in Eurasia, although faunal exchange across the Bering land bridge may have been possible during a major sea level low stand as early as the late Eocene (about 37 Mya) and continuing into the early Oligocene.
