The specific information of the marsupial wolf ... who knows? be badly in need of
When early immigrants came to Australia, people had to occupy more land to develop agriculture and animal husbandry. They regard the wombat as a hateful enemy, because it is a great threat to their sheep. Although many sheep are actually eaten by dogs, human beings are very angry with marsupials, and the government has also joined in this big encirclement and suppression of marsupials. 1888, in order to develop animal husbandry, the Australian government offered a reward for killing many marsupials, so the fate of marsupials began ... The last wild marsupials died in 1939.
1948, with the death of a lame marsupial wolf in Hobart Zoo, this originally huge family system disappeared from the earth.
Ironically, it was not until recent years that people realized that the marsupial wolf is an animal that needs protection. 1966 in the southwest of Tasmania, with a glimmer of hope, people set up a reserve for marsupials that may survive. However, the Australian government suggested that the reserve be removed because this species no longer exists. What is lost is often the most precious, and history cannot be repeated!
The marsupial wolf, which once thrived in Tasmania, Australia, was extinct 70 years ago because of the indiscriminate killing of human beings. Biologists decided to use DNA samples obtained from specimens for biological cloning project, hoping to make marsupials reappear on the earth.
There are 1 small pieces of animal fur near the entrance of Bonnoron Park Wildlife Center. The description next to it shows the fur of a Tasmanian tiger. But in fact, there is no trace of this animal in Australia.
A group of biologists in Australia believe that marsupials that have been extinct for 70 years are expected to reappear on the earth; Because they discovered the cellular deoxyribonucleic acid (DNA) substance of this animal, they are currently carrying out a biological cloning plan.
Although the English name of the marsupial wolf has the word "tiger", it is actually not a cat, but a marsupial creature like kangaroo. According to the literature, the marsupial wolf appeared in front of the world for the last time in 1936, but this "last marsupial wolf" was killed by human beings. From then on, people can only mourn for the marsupial wolf in museum exhibitions or fairy tales.
The scientists extracted DNA samples from a museum in Australia. This 6-month-old wombat specimen has been soaked in alcohol since 1866. Jakker, curator of the museum, said that he was convinced from 15 years ago that this specimen would be the key to the reappearance of marsupials on earth. However, it was not until 1997 that the British scientist successfully completed the plan of cloning Dolly the sheep, and his dream finally came true.
Although about half of the scientists think this plan may fail, Jaeckle is optimistic that the reappearance of wombat on the earth is no longer a hypothetical dream, but a question of when it will come true. A group of scientists in Sydney extracted samples of heart, liver, muscle and bone marrow from this specimen in April this year and began to study the genetic code of this animal. Once the researchers recover the damaged genetic code of the specimen, they will implant the genetic blueprint into the eggs of Tasmanian devil or Numbat, close relatives of Tasmanian wolves, for cultivation.
Although there are plans to clone extinct animals in many parts of the world, the wombat cloning project in Australia is the first research project to obtain high-quality DNA samples. However, due to the complexity of the cloning project, Jakker estimated that it would take 65,438+00 to 65,438+05 years for the marsupials to reappear in front of the world.
According to the specimens and photos of marsupials in Germany and Switzerland, marsupials are marsupials that look like dogs, with brown fur, black stripes on the back and lower buttocks, and a thick tail like a kangaroo. In addition, like distant kangaroos and close relatives of Tasmanian demons, female Tasmanian wolves will raise their young with a pouch structure in their abdomen.
Marsupials were once distributed in mainland Australia and New Guinea. However, since humans introduced wild dogs to New Guinea about 6,000 years ago, marsupials here have disappeared. When British whites went to Australia to pioneer, they only saw the trail of marsupials in the southeast of Tasmania. However, these pioneers wiped out marsupials as enemies, because marsupials would prey on sheep and other animals raised in farms. After Australian pioneers began to reward the head of the marsupial wolf with a bonus of 1888, hunting the marsupial wolf became one of the local profitable industries.
