In the current situation, is there no new species on the earth?

I think there will be new species born in nature. New species may be born on the earth all the time, but the range that humans can observe is very small, and even if new life is formed, humans cannot know it at the first time, after all, they will not come to tell humans. If no new species are born in nature, then there will be fewer and fewer species in nature and gradually become extinct with the phenomenon of eugenics.

The development of modern science and technology makes us feel that the earth is very small, but in fact, the scope of human exploration of the earth is still very small, the ocean accounts for 71% of the earth's area, and human beings have observed less than 10%, through the detection of the Mariana Trench, there is life at all depths of the ocean, and in the past, Russia's Kola ultra-deep drilling crater and modern comprehensive ocean drilling program have found microbial populations below 1000 meters underground, and every time human beings carry out deep-sea exploration, It is possible to discover several new creatures, but in fact they have existed for a long time, but humans do not know about them.

The total number of life species on the earth is far beyond human imagination, so far there are about 10 million species of organisms that have been recorded and named, and even some algae microorganisms have been found in the atmosphere 17-20 kilometers from the ground, and we cannot know how many species really exist in the world, according to ** There are at least 30 million species, they have adapted to different environments, and continue to evolve with changes in the environment. New organisms are created almost every hour every day, but we don't know because they don't come to us at high speeds.

The replicability of genes determines the reproductive characteristics of organisms, and in the process of gene replication, there will be "errors", most of which are harmless and not beneficial to the survival of organisms, they are inherited with the reproduction of organisms, but when the environment changes, a gene may become the key to the survival of organisms, which is more conducive to the survival of organisms, so organisms evolve, and over time new organisms are produced.

No. Because the earth's environment is constantly changing, and the evolution of living things is constantly going on, and many new species are born every year, it is not that the earth is no longer giving birth to new species.

No, the birth of a new species is a particularly long process, and it is impossible to discover a new species in a short period of time.

The birth of a new species is measured in 10,000 years, for example, it took millions of years for humans to evolve from Australopithecus to Homo sapiens, so it will take at least a few decades for a new species to appear.

Now, the earth's environment, on which we humans and animals depend, has been deteriorating more and more, and many wild animals.

are on the verge of extinction.

We also feel very sorry that scientists are also studying how the earth is producing a variety of animals, and they are also trying to understand how to regenerate extinct species, but it is not possible. So how did the animals on Earth first come into being? And why don't extinct species regenerate?

Next, let's take a look at these two questions!

First, a variety of environments have made the generation of animals The mechanism of the earth to breed organisms is very magical, at the beginning there were some macromolecular substances on the earth, and these macromolecular substances spontaneously formed a membrane structure on the surface, so there were single-celled organisms on the earth.

These single-celled organisms evolved and differentiated under the influence of their environment, eventually forming multicellular organisms. Then multicellular organisms evolved and differentiated, forming the animals, plants, and microorganisms we have today.

Second, we can no longer reach the previous environment The earliest extinct animal we know is the dinosaur, and many fossils of dinosaurs have been found, and dinosaurs were born in ancient times.

At that time, there were no human beings, and there were not many living things, just patches of forests and trees. Therefore, taking dinosaurs as an example, the earth's environment is changing all the time, and we currently have no way to return to the previous ecological environment, "natural selection, survival of the fittest", so nature cannot resurrect extinct animals.

3. Protecting wild animals, everyone is responsible now, the earth's environmental pollution is becoming more and more serious, and the ecosystem.

The balance is disrupted. The rate of extinction of species is accelerating, which means that the diversity of organisms is decreasing, which may eventually lead to the extinction of human beings, so we must start from ourselves to protect the ecological environment on which we depend, and at the same time protect the wild animals, which is everyone's unshirkable responsibility.

Animals on Earth were first born through mother's conception, and the reason why extinct species do not regenerate is because such species no longer have the ability to breed, so they will not appear again.

It can only be said that the environment at that time was more suitable for the survival of those creatures, so it appeared, and now with the development of the environment, it is no longer suitable for the existence of the original creatures.

Because the earth's environment was in a relatively ideal state at that time, a lot of primitive life was bred because their biological signs had been completely destroyed.

From a biological point of view, the birth of a new species is the formation of a population, then the formation of a category, and finally the formation of a species, which takes a long time in the middle, and cannot be observed by one or two generations. But this does not prevent us from verifying the correctness of the theory.

Just look at the dog, the dog is domesticated or cultivated by the wolf, and now it has formed countless defeated populations, Chow Chow Demu Erha, each of which can be inherited traits, and can also reproduce, it can be said that it has transitioned from the population to the category, and then the development of different dog breeds will produce reproductive isolation, which can be defined as a new species.

By the way, reproductive isolation is not a criterion for defining species, there is no reproductive isolation between ligers but they belong to two species). There are more new species in plants, but they are not so famous and unknown to the general public.

New species are born, but the time period since we have recorded them is too short, and there are always new mutations, such as many new bacteria, viruses, symbionts, and large populations are not enough to appear obvious new species due to time relations, and it takes a long time for the new species to stabilize.

It was concluded that in order to adapt to the environment, subspecies constantly appeared. After all, human beings have a very short understanding of the world, so quantitative changes have not yet caused qualitative changes. In fact, many new species are born, but the number of new births is very small and difficult to find.

In fact, there are really a lot of new species born, many of which are actually no different from the old species, but as long as there is reproductive isolation, it is called a new species, and now it is known that there are many, many new species cultivated by artificially, and then because of the current ecology, nature has also evolved a lot of new species, but the extinction of old species is easy for us to detect, and the emergence of natural new species has to wait for us to discover, so there are relatively few mentions, but definitely a lot.

In fact, every year, new species are found to replace the extinct old species, for example, the Amazon often discovers new species, nature will definitely solve its own problems, but humans should not be nosy. Stay optimistic.

The species on the earth fiber cover are all developed through continuous evolution and reproduction, and the evolution of each species takes hundreds or even thousands of years, and the current species have evolved from the previous cells.

Now the most convincing Li Fu is that all life is born from the ocean, from the earliest single cell, and gradually multiplies to the current scale of the sedan friend, which makes people sigh at the miracle of life.

Species on Earth were brought about by meteorites from outside the earth, and they have evolved to become what they are now.

Nature is because of the evolution of animals, each animal continues to evolve with different changes in the environment, those who adapt survive, and those who do not can only face extinction.

Species on Earth have evolved over thousands of years and are not born in an instant.

According to Darwin's "Theory of Evolution", the species that exist in the world are constantly evolving and evolving, and the species on the earth are the result of the mutual run-in of the substances of nature!

It is currently in the fifth extinction. Although new species are being created, they are still extinct faster than they are created.

Species extinction refers to the gradual disappearance of biological species from the world due to natural or man-made causes. Biological species, like anything else, have a process of creation, development, and extinction. In the natural state, one species dies and new ones arise and develop, thus maintaining the diversity of biological species on the planet.

However, due to human intervention, the rate at which species disappear can be greatly accelerated. From 1600 to 1800, 25 species of birds and mammals on Earth went extinct; From 1800 to 1950, 78 species of birds and mammals on Earth became extinct. The causes of species extinction are mainly due to the destruction of the ecological environment, the irrational exploitation and utilization of human beings, the pollution of the environment and the introduction of alien species.

Species extinction is a huge loss of biological gene pool, which directly affects human production, life and the ecological balance of nature. Preventing species extinction has become a global imperative.

However, one thing to consider is that before the advent of humans, there were only two motives for animal evolution: natural selection and sexual selection; After the advent of human beings, a third dynamic emerged: artificial selection.

Therefore, human beings are partly responsible for the extinction of species after the emergence of human beings. Humans have begun to assume the role of God.

The Earth is home to countless species of life that live on this planet in a variety of different forms and characteristics. While some species have died out over a long evolutionary journey, there are many others that are still active in all corners of the planet, bringing us endless surprises and challenges.

Among these active species, the most representative is humans. As the apex predators on Earth, humans have been living on Earth for more than 200,000 years. Through innovations in language, tools, and culture, humans have evolved to become one of the most intelligent species on Earth.

While humans have brought inevitable environmental destruction and species extinction, they are also actively protecting and rebuilding the natural world.

In addition, in addition to humans, other representative animal species on Earth are also active. For example, elephants are one of the largest land animals on the planet, dolphins and whales are the most intelligent creatures in the oceans, and pandas and orangutans are among the most caring and humane animal species. These animals all survive in different ecological environments and play a vital role in many aspects of the Tachibana Bridge's ecosystem.

In addition to animals, the plants on Earth also contain countless species. For example, spruce is one of the oldest tree species, giant redwood trees and oak forests only grow in a few specific places, and hypericum and jasmine are among the most popular garden flowers. The way these plants reproduce and grow is what makes their beauty and popularity ever-expanding.

In general, the biological species on the earth are diverse, and they complement each other with extremely different characteristics, habits and advantages, forming a complete ecosystem. Although humans have posed a great threat to certain species, we should still contribute to the diversity of life on Earth in ways that protect and rebuild the natural world.
