Since 2021, there is still a lot of news about the reappearance of disappearing organisms on the earth, and we have just said that some people say that the thylacine that has been declared extinct for 85 years has reappeared on the earth, and Indonesia has announced the discovery of a mysterious bird that has disappeared for 170 years, and the photos are clear, it can be fully identified, it is really amazing, this is the update of the creatures in nature? Or is it that this creature did not go extinct in the first place, so it formed signs of biological recurrence.
In itself, the reproduction of the organism is a very happy thing, which illustrates the improvement of the ecological environment, but as long as it is found, it may also face the possibility of real disappearance, the more scarce the easier to attract attention, let's see this disappearing creature is a bird.
<h1 class = "pgc-h-arrow-right" disappeared > 170 years, and the thrush reappeared on Earth</h1>
According to scientific reports, this mysterious thrush is the "black-browed babbler", which belongs to indonesia's endemic species. For a long time, this creature has lived outside the sight of humans, according to scientific estimates, it is only possible to distribute in Borneo, and the organism has only one specimen found in the 19th century, so it is a very scarce biological population, in general, the black-browed grebe lives in subtropical or tropical lowland forests, but there are too many cases that scientists do not know.
Although it has disappeared for 170 years, scientists have not recently defined it as extinction, because of the lack of research evidence, so this time it is confirmed, and a trace of a black-browed stork has been found in Borneo, Indonesia, and there are photos to prove it. Its existence can finally be confirmed, and now the scientific community has published a description of the relevance of the creature in the journal BirdingAsia, so it has extremely high value, which is an unusual bird, after scientists discovered the creature, took a picture and released it.
Of course, through the appearance, many people may not think that this is a unique organism, in our country there may be people have seen similar organisms, but is not the same population, to be identified, so we do not casually define the population of organisms, but now confirmed that the disappeared 170 years of thrush reappeared on the earth, is a good thing, before there is no evidence of correlation, so it is called "the biggest mystery in Indonesian ornithology".
< h1 class= "pgc-h-arrow-right" > why do vanished creatures reappear? Is evolution wrong? </h1>
The reappearance of a creature that has disappeared is most likely because it did not survive in human vision, so its footprints were not found, and it is not an evolutionary error. Another is the fact that this creature has undergone a special evolutionary pattern, such as the white-throated rail, which attracted worldwide attention when it was first announced, because through fossil archaeology, biologists found that it had become extinct on islands in the Indian Ocean about 136,000 years ago, and it was impossible to appear.
But later, human beings discovered its existence, and through analysis, this creature appeared through a special way of evolution, repeated evolution. Repetitive evolution is in the history of an evolutionary branch, at different times to repeatedly derive morphological branches, often there are millions of years of intervals between each repeating branch (also known as repeated evolution), so this is the recurrence of organisms that are considered extinct, of course, the thrush is not considered extinct, but the disappearance time is also relatively long - 170 years.
In these 170 years, humans have not found that it is also a miracle, either this creature has also appeared to have repeated evolution, or there is no extinction, but the population is relatively small, but as a unique species in Indonesian Borneo, it is also a miracle that it has not been found, and the place is too small to withstand such a strong search, so what is the specific reason, there is no news for the time being, let's take a look at the global overall biological population.
< h1 class="pgc-h-arrow-right" > Earth's population is declining</h1>
Nowadays, it is very difficult for us to hear that the disappeared, even extinct organisms reappear on the earth, because the overall biological population of the earth is in the process of large-scale reduction, so their appearance gives us a little more confidence in protecting the ecological environment, but the overall biological population of the earth is decreasing, which is an undeniable fact. According to the WWF 2020 report, the global wildlife population decreased by 68% from 1970 to 2016.
Freshwater organisms have changed the most, with monitoring data from 944 species and 3741 populations showing an average decline of 84 percent, equivalent to a 4 percent decline per year since 1970. Including crawling, fish and other species groups, so this part may be the most related to humans, most of the freshwater creatures are fishing objects, even the top food chain whales on the earth, are the objects of hunting and eating, we will say other, there must be.
So in general, the biological population is decreasing on a large scale, which is an undeniable fact, which also shows the importance of human beings to protect biological populations. The decline in the number of wild animal populations and the serious decline in plant diversity will lead to imbalance in the earth's ecosystem, climate change, overexploitation of land and marine resources, etc. is one of the main factors in the decline of animals and plants, so it is urgent to protect animals and plants globally, otherwise there will be few opportunities.
