Since the earth has been recorded, there have been a total of 5 mass extinction processes, which can be said to have led to the disappearance of most of the organisms on the earth, and then a new species group has emerged, that is, the population of our modern society, which is equivalent to a new species group after the extinction of the dinosaurs. With the destruction of the ecological environment, many scientists have issued a warning that a new round of species extinction after the extinction of the earth's dinosaurs may be accelerating, which is not a good thing for the earth's biological population.

For the earth, if there is a mass extinction of the biological population, then the earth's ecosystem will be completely extinct, including us humans may also be affected, of course, we need to say that a genitive creature reported by the Daily Mail may reappear, that is, the declared extinct organism may come back, very rare in nature.
Generally speaking, it is impossible for animals to declare extinction, and this time it is a mammal living in Australia. The back is covered with stripes, because of its striped tiger, also known as the "Tasmanian tiger", which is the "thylacine", which is the largest carnivorous marsupial in modern times, which originally lived in the rainforest of New Guinea, the Australian grasslands and other places, and is widely distributed, that is, the population of organisms that can be seen everywhere.
However, due to human activities, the "Tasmanian Tiger" soon became extinct or disappeared in most areas, until finally only Tasmanian Tiger existed, other areas were extinct, and the last "Tasmanian Tiger" died in 1936 at hobart Zoo on Tasmanian Island, so there is no longer a "Tasmanian Tiger" in the world.
But in 2016, in the fields of Victoria, Australia, someone suddenly photographed the Tasmanian tiger galloping, which was the first time that humans declared extinction for 80 years to find it, which was very surprising, and Neil Water, an expert of the Tasmanian Tiger Conservation Association, also said that this is the Tasmanian tiger, so this is very surprising, and this suspected "tiger" creature has once again attracted everyone's attention and hot discussion.
After the acquisition of this species in Australia, although the conservation society experts said that it was the "Tasmanian tiger", it still needs further confirmation to know, and after shooting here, there have been no reports related to the species, so it is still unknown whether this creature is there, that is, the authenticity of the scientific community is still inconclusive. If the Tasmanian tiger really exists, it is a miracle, because this situation is very rare in nature, and it is generally impossible to have such a situation, and the reappearance of extinct organisms is basically not recognized.
But there are also "accidents", such as scientists have found animals that do not breathe, and no one on Earth believed that such animals existed before, but it turns out that humans have discovered the appearance of such animals. Although it is a small probability event, it may also occur. What kind of species is the Tasmanian Tiger? The species is not a very large biological group, with a shoulder height of about 58 cm and a body length of about 180 cm, this length includes a tail of 48-61 cm, weighing 30 kg, so it belongs to a small biological population, generally nocturnal, which is a basic condition of it.
Many people say that there is no scientific basis for the reappearance of extinct organisms, but it is not nothing, it is just relatively scarce. For example, in the article on the reproduction of the extinct species "White-throated Buzzard" 136,000 years ago, we see scientists saying that there is "iterative evolution", and there is a situation that allows a species to evolve twice, especially in such a short period of time, such a situation is very rare, so the reappearance of extinct organisms is scientifically based, not empty talk.
Of course, in most cases, this pattern is unlikely, and scientists say it is very rare. It is usually because of the "hidden" or primitive habitat migration of the creature that humans did not find, and finally announced the extinction, but in this case, scientists have not found it for decades, which is also a miracle. After all, for most biological populations, the earth is such a big piece of land.
Since the industrial age, humans have changed 75% of the earth's land and 66% of the marine ecosystems, and it is difficult to hide them.
From the perspective of normal geographical theory, the remaining areas that have not been destroyed may be areas that humans are not willing to touch, the ecological environment is generally not good enough to go anywhere, and the organisms themselves are also adaptive models, so the reappearance of extinct organisms may be in line with "repeated evolution" or more, and the possibility of habitat migration being hidden is slightly lower. This is not a violation of the laws of biological evolution, but it is also a new evolutionary path.
