The core of life is evolutionary evolution. It is through billions of years of evolutionary evolution that life on earth has the present colorful biological world and the birth of mankind. The evolution of biology is not chaotic, but has a certain regularity.
The evolution of living things needs to abide by some natural laws, and “appearance and disappearance” is one of them. In the long evolutionary years of life, many kinds of creatures have become extinct and disappeared, and some creatures that were already extinct and disappeared will have a certain chance to appear in the later evolutionary years.
The birth, evolution and survival of mankind also follow the laws of nature. Due to the birth and development of mankind, the earth’s ecological circle has also undergone tremendous changes, and nature will also adjust the ecology of various influences after the emergence of mankind. Although the birth of mankind made the earth a rare civilized planet, human activities have also brought a faster and worse impact on the biological world.
When human beings enter the era of science and technology, the impact of human beings on the earth’s ecology and the biological world is increasing. Although with the help of science and technology, the living standards and life span of human beings are constantly improving, but in the natural state, it is important for people other than human beings. For other wild animals, the disappearance and extinction are accelerating.
In the past 100 years or so, many species on the earth have become extinct or on the verge of extinction. As we said earlier, in the laws of biological evolution, there is a law of “appear and disappear”, and some have disappeared for a long time. The creatures may appear. So have long-lost creatures reappeared on the earth now? The answer is yes.
According to scientific records, there is a giant tortoise named Fernandina in the Galapagos that has disappeared for 113 years. According to scientific reports, since scientists discovered the giant tortoise in 1906, Fernandina has disappeared. The creature was never seen again, and some even said it might have become extinct.
But this giant tortoise, which has disappeared for 113 years, was discovered by scientists in an accident. The disappearance and reappearance of this mysterious creature has aroused heated discussion in the scientific community. People are discussing why this giant tortoise can reappear after 113 years of disappearance? You know, the environment of Fernandina Island is very sinister, and there are often volcanic eruptions.
Under such a harsh environment, the survival of organisms is inherently very difficult, and once a species disappears for a long time, it basically means that such species have become extinct and will not reappear in the future. But the biological world is so magical, and the law of “appear and disappear” once again teaches us a lesson.
Regarding the reappearance of the Fernandina giant tortoise 113 years after its disappearance, more people still believe that this giant tortoise may have been living in a very hidden place on Fernandina Island for 113 years. The fact that it has not been discovered by us does not mean that it has disappeared for 113 years. It is just that it has been living on the island for a hundred years, but we humans have not discovered it.
Even so, it shows that this giant tortoise is an endangered creature, and it is possible that the Fernandina giant tortoise discovered by scientists now is the only remaining Fernandina giant tortoise in the world. The Fernandina giant tortoise is unlikely to be a creature that will reappear after extinction. It has a high probability that it has survived in the biosphere, but humans have never discovered it.
So are there other creatures that have disappeared for a long time and reappear? Nature exists. Scientific love once discovered a kind of “diphtheria croaker” that has been extinct and disappeared for 136,000 years. This is a kind of bird that has been extinct for 136,000 years. However, there has been “repetitive evolution” in the process of biological evolution, so it has appeared in the modern biosphere.
In this way, some ancient creatures that once appeared on the earth have been extinct for a long time, but in the future with the continuous progress of biological evolution, they may reappear on the earth, such as the extinction 65 million. Dinosaurs may also reappear at a certain time in the future.
The reappearance of disappeared organisms is of course a good thing for the earth’s biosphere. It can enrich the earth’s biosphere. It’s just that if we want to make the earth’s creatures continue to “repeated evolution” in the future and allow more ancient creatures to reappear, we need a healthy and stable ecological environment.
However, according to the current situation of the continuous destruction of the earth’s ecology by human activities, it is not easy to achieve such a goal. What’s more, there is another natural law that the earth’s biosphere needs to follow, which is the mass extinction of living things. In the biological history of the earth for nearly 400 million years, there have been five mass extinction events.
These five mass extinctions are not completely irregular. According to the research and exploration of scientists, the mass extinction may be a natural law that the biosphere must follow. This may also be a rule that must be completed on the evolutionary road. According to the average time period of the mass extinction, under the correct circumstances, the earth may usher in the sixth mass extinction event in about tens of millions of years.
For humans, tens of millions of years is a relatively long period of time. With the speed of human technology development, there should be no worry that humans will disappear because of the mass extinction in tens of thousands of years. So will the sixth mass extinction come in accordance with the time period given by the laws of nature? Probably not.
Because after the industrial revolution, human beings continue to destroy the ecological environment, and the continuous deterioration of the ecological environment is accelerating the arrival of mass extinction. There are tens of millions of biological extinctions that could be ushered in, and it may come hundreds of years later.
In June 2020, a new round of research reports also pointed out that the sixth mass extinction has accelerated at an unprecedented speed, which has triggered people’s worries about the extinction or disappearance of organisms. By studying the distribution of endangered species around the world, the scientific research team gave preliminary data that they found that 515 endangered species (accounting for 1.7% of the total number analyzed by the research team) are on the verge of extinction. It is possible Disappear in the next 20 years.
Although we have seen the reappearance of disappeared creatures, which can add a species to the earth’s biosphere, the environment continues to deteriorate, and the number of species that are on the verge of extinction and extinction is increasing every year. The overall scale of the Earth’s biological populations is shrinking. If this situation continues, even if humans’ scientific and technological capabilities become stronger in the future, then there may only be one species left on Earth. This is a sad thing. thing.
