Thylacine (Tasmanian Tiger) thylacinus cynocephalus harris English name thylacine, tasmanian wolf Once widespread in the Australian continent and nearby islands. European immigrants to _set_tle in Australia, the Australian continent became extinct thylacine, just south of Tasmania in Australia, there is distribution of the island. Some people think that wild populations have already become extinct. Body shape of a dog, head like a wolf. Shoulder height 600 mm, 750 mm body length, tail length 530 mm. Tuhui or yellow brown coat, the back bar black belt students have 14-18 spots. Short hair is very dense and hard. Gape very long. 5 toes front feet, hind toe 4. Inhabit open woodlands and grasslands. Going out at night to feed, shelter in the gravel of the day. Individually or in the form of multi-family category feed kangaroos, small mammals and birds. Because of its large gape, prey, predators will often crush the skull. Summer mating, each Aberdeen 3-4 births. Pouch in the female pups fed animals after 3 months alone activities, but still stay around a dam about nine months. It is a subsidiary】 【indescribable wonderful animals. Its head and teeth from the point of view, it is a wolf. However, its body like a tiger has stripes. It can be like running on four legs, like hyenas. Can be as small as kangaroos jumping hind legs to walk, it, like the kangaroo is a marsupial with the animals. This animal has the characteristics of other types of animals, but has a special place, it is the people called the Tasmanian wolf, zebra wolf, as well as the Tasmanian tiger and so on. Since the immigrants came to the island of Tasmania, the thylacine's survival was followed by a crisis. A large number of livestock - sheep, dogs hurt. And people are mistaken for the thylacine, because dogs and wolves are the bags suck the blood of sheep. 1888, the Government offered a reward of thylacine reward people killed, two decades after that among the total of two thousand two hundred sixty-eight thylacine was hunted out. This is the record number of thylacine valuable information. Finally, a thylacine, was killed in the 1933's.

About Signs
Once widespread in the Australian continent and nearby islands. European immigrants to _set_tle in Australia, along with the intervention of human activities, wild populations have become extinct. Body shape of a dog, head like a wolf. Shoulder height 600 mm, body length 100 to 130 cm, tail length of 50 to 65 cm. Tuhui or yellow brown coat, the back bar black belt students have 14-18 spots. Short hair is very dense and hard. Gape very long. 5 toes front feet, hind toe 4. Back belly pouch opening, the bag has two pairs of nipples. Thin and long tail. This is an indescribable wonderful animals. Its head and teeth from the point of view, it is a wolf. However, its body like a tiger has stripes. It can be like running on four legs, like hyenas. Can be as small as kangaroos jumping hind legs to walk, it, like the kangaroo is a marsupial with the animals. This animal has the characteristics of other types of animals, but has a special place, it is the people called the Tasmanian wolf, zebra wolf, as well as the Tasmanian tiger and so on. Thylacine

Habits
袋狼 生活习性
Inhabit open woodlands and grasslands. Going out at night to feed, shelter in the gravel of the day. Individually or in the form of multi-family category feed kangaroos, small mammals and birds. Because of its large gape, prey, predators will often crush the skull. Summer mating, each Aberdeen 3-4 births. Pouch in the female pups fed animals after 3 months alone activities, but still stay around a dam about nine months. Thylacine live in the woods where a more sparse, or grassland. However, the migrants came to the land they live on, they will go hide in the deep forest. By stomach has put as little like a kangaroo pouch kangaroo. A pattern on the back. Jaw bone is divided into two open like a snake, they will chew dog Cameroon rip about the head. Night, they act alone, often in kangaroos, wallabies, or flightless birds, the target for the hunt. Its running speed is not fast, but it will hot pursuit, until the game so far exhausted. They are often the first to bite the prey end of the game of life.

Thylacine's extinction
袋狼的灭绝
Since the immigrants came to the island of Tasmania, the thylacine's survival was followed by a crisis. A large number of livestock - sheep, dogs hurt. And people are mistaken for the thylacine, because dogs and wolves are the bags suck the blood of sheep. In 1888, the government offered a reward of thylacine reward people killed, two decades after that among the total of 2268 bags were killed by wolves. This is the record number of thylacine valuable information. Finally, a thylacine, died in 1936. Died in the island of Tasmania, Hobart zoo. People in Australia found the ancient inhabitants of the rock in a million years ago, drawn to the mural, from which we know in the long, long time ago, the thylacine had to survive in this ancient land. Magically, now, in Tasmania the island, there was a thylacine protected areas. This is shown to be a psychological compensation? All in all, these precious animals - extinct thylacine. While living together with Australia's indigenous people more than a thousand years. However, with the New World was discovered, in a flash, the thylacine finally disappeared forever on earth.

History of thylacine
The National Zoo in the 1902-1905 years, a pair of bags by keeping the wolf came after 1936 have been exactly like the bags of wolf attacks on livestock animals in New Guinea, news, and many witnesses said they saw thylacine, but there is no irrefutable evidence Thylacine still really can prove to the world. 1967 corruption was found in a cave animal carcasses, is identified by experts as the thylacine body, but whether its fresh mummified bodies left behind years ago, scientists or divergent views. Thylacine is extinct, is not known. 1999 Australian Museum in Sydney, Mike Eqi found a museum since 1866 are stored in alcohol wolf pouch specimens, Mike Eqi proceeded to study the thylacine DNA extracted from the possibility of resurrection, May 13, 2000 Also found in six similar museums in other specimens, making more complete the relevant gene pool. Mike E Qi said, the thylacine in the fifty years through gene duplication technology to reproduce the world.

Thylacine gene duplication
袋狼基因的复制
Australian and U.S. scientists May 20, 2008, said they had been extinct thylacine (Tasmanian tiger) of DNA into mouse embryos and embryos in the formation process of cartilage and other skeletal played an important role; this way, though still far away from the copy of dinosaurs, but extinct animal genetic component to obtain the information, and the other is expected to be used to develop new biological medicine. University of Melbourne, Australia Professor Andrew Pask led the study, said: "This is the first use of the extinction of species extracted from the DNA, the other living organisms to induce production of functional response. With more and more animals into extinction, we are constantly losing the understanding of gene function and its potential. "So, the new study may help to reverse this situation. Tasmanian Tiger The latest research shows that extracted from the extinct animal DNA can be re-activated. Thylacine length 5 feet (1.52 meters). Early 20th century, the wild thylacine was hunted bare. In 1936, the end of a thylacine in captivity in the island of Tasmania, Hobart Zoo died. But some thylacine pups are well preserved specimens. Thylacine Museum has collected several organizations, and saved as alcohol collections. Parks's team extracted DNA fragments, _select_ed an "enhancer" and a produce collagen Col2a1 gene. Although it does not in itself a gene, but the ingredients to help gene to function. This DNA into mouse embryos, the it was "open" to help the cartilage (the initial stages of the formation of bone) development. The study was published in the "Public Library of Science - Integrated Research" magazine, the scientists said the study of extinct animals to understand the biological characteristics of great help This study by the University of Melbourne, Australia and the United States to complete cooperation with the University of Arizona, the team saved by Museum Victoria in Melbourne Thylacine tissue samples, the removal of the Col2a1 gene DNA fragments (II collagen gene), and then injected development of mouse embryos and found that: the control thylacine Col2a1 cartilage generated Col2a1 gene and mouse genes have similar performance, bone formation in mice is very important. Department of Zoology, University of Melbourne, Prof. Fu Li said that the current extinction rate faster biological amazing, especially mammals, so the results of this study is significant; researchers used the method shows that extinct animals can be exposed to biological polymorphism sex, it was rooted and Lost. Pask said that such use of extinct animals, DNA is expected to develop new biological medicines, such as cartilage can promote the rejuvenation of the gene. University of Texas Professor Bellenger said the experiment has huge potential for multiple use, such as a better understanding of the biological role of animal extinction mechanism.
