The transitional phase of science is often accompanied by a brutal negation phase, and no matter what kind of science it raises, it cannot escape this link. Pen & Fun & Pavilion www.biquge.info

Darwin's theory of evolution is that in the middle of the 19th century, Darwin founded the scientific theory of biological evolution, with natural selection as the core, for the first time made a materialistic and regular explanation of the occurrence and development of the entire biological world, overthrew the dominance of idealism and metaphysics such as creationism in biology, and made a revolutionary change in biology.

After the Renaissance and the Enlightenment, the rational thinking of modern science was established. Darwin's era was in the mid-to-late nineteenth century, which was the previous stage of getting out of ignorance and advocating science, which provided the ideological basis for Darwin to establish the theory of evolution by natural selection in terms of thought and reason. The travels of his youth accumulated a lot of evidence for him, which led him to think about the evolution of species and finally formed a complete system. It is undeniable that due to the lack of development of science at that time, the theory of evolution had theoretical defects, but with the continuous progress of science, the theory of evolution has developed into the modern comprehensive theory of evolution.

In fact, there is only one purpose in opposing evolutionary theory - to draw out God. Now these opponents of evolution are very obscure, not directly saying that God was created, but intelligent design, but there are only two possibilities for the question of how species appeared, one is natural evolution, and the other is creation. Even if life on our earth was created by aliens, then where did the aliens come from is still a question, and there is still a question of whether they evolved or were created.

The denial of evolution, that is, the natural introduction of the creator, if the creator is alien, then the problem is not fundamentally solved, therefore, in the end, only the creation of God is the fundamental purpose, God does not need to be created in religion, which is why anti-evolutionists are basically religious, and creation theory, no matter what the name is, will not add the slightest value to scientific research.

There is a struggle for survival between living things, the adaptors survive, and the unfit are eliminated, which is natural selection. It is through heredity, mutation, and natural selection that living things evolve and develop from low to high, from simple to complex, and from few to many.

Species are mutable, existing species are changed from other species, and one species can become a new species. This has long been confirmed by observations and experiments in biogeography, comparative anatomy, comparative embryology, paleontology and molecular biology, and the emergence of new species can be directly observed in the laboratory and in the field. Therefore, this is a scientific fact that is as reliable as "the earth is round" and "matter is made up of atoms". Today, with the exception of a few people who ignore the facts because of religious fanaticism, there are practically no biologists who deny the fact of biological evolution.

All living things come from a common ancestor. Molecular biology discovered that all living things use the same set of genetic code, and biochemistry revealed a high degree of consistency at the molecular level, which ultimately confirmed Darwin's vision. So, this is also a generally accepted scientific fact.

It is now generally accepted in the academic community that the use of natural selection is not as widespread as Darwin had envisaged. Natural selection is the mechanism of adaptive evolution (i.e., the adaptation of organisms to their environment), and for non-adaptive evolution, there are other mechanisms such as genetic drift. That is, all evolutionary phenomena cannot be explained by natural selection. Considering that adaptive evolution is the core phenomenon of biological evolution, it is also valid to say that natural selection is the main mechanism of evolution.

During Darwin's lifetime and for a long time after his death, most biologists, especially paleontologists, believed that biological evolution was capable of leaps, that new forms and organs were the result of large leaps, rather than small variations that accumulated slowly and gradually by natural selection. Some paleontologists, including Huxley, have held this view because of their emphasis on the discontinuity of fossil organisms. For some time after the birth of genetics, early geneticists also generally accepted the theory of transition because of their emphasis on the discontinuity of inherited traits.

The theory of evolution is the second major scientific breakthrough in human history. For the first time, heliocentrism replaced geocentrism, which denied the arrogance complex of human beings at the center of the universe; The second is the theory of evolution, which pulls human beings to the same level as ordinary creatures. All the creatures of the earth have a distant or close blood relationship with human beings, completely breaking the ignorant self-esteem of human beings who are arrogant and arrogant, under one god and above all beings.

It's true that species evolve, but what are the reasons for evolution? Why do species mutate? Why do species evolve from simple to complex, from low to high? Before Darwin, there were evolutionists who tried to answer this question, but their answers were either factual or far-fetched. Darwin summed up and discarded the theories of his predecessors, and paid attention to absorbing nourishment from the academic ideas of other disciplines, and after years of hard exploration and intense thinking, he put forward the theory of natural selection to explain the fact of biological evolution.

How do new species emerge? Because old species mutate, why are so many species extinct? Because they can't withstand the pressure of the struggle for survival. Why is the relationship between living organisms and the environment so harmonious? Because some of the countless variations fit the choice of the environment. As to why lower types of organisms are everywhere, Darwin wrote: It is not difficult to understand, because natural selection, i.e., the survival of the fittest, does not necessarily involve progressive development—natural selection only uses those variations that benefit organisms in complex life relations.

Correspondingly, the emergence of new species means that there will be another batch of old species disappearing, and the same is true for science, when new science appears, the old science will disappear, from the position of people to denial, from a sacred position to ignorant rumors, and there will be a lot of sacrifice in the process.

But now that Lin Feng is here, the old science base is now in a transitional stage, but people have discovered new science but can't confirm it, or it may be that new science has been discovered but can't develop real things, so no one agrees.

However, there are many products of modern science in Lin Feng's supermarket, so it is only appropriate for Lin Feng to witness the evolution of science. (To be continued.) )
