Not quite right. First, the theory of evolution.
It is an assumption in itself, and there are many contradictions or imperfections. It is very dangerous to be drawn into social value judgments all at once. The Industrial Revolution in the Modern West.
In order to find a suitable excuse for capital accumulation, the "survival of the fittest" of the evolutionary theory has been introduced into the value orientation.
As a result, it became a matter of course to be beaten backward. Humanity has thus entered a situation of bullying and cannibalism, and at the same time jealousy, ignoring nature, and violating the law. The dangers are only now being realized.
In addition, people are human beings, not animal-like killing and devouring. In the final analysis, the civilization of society does not depend on Darwin.
The so-called competition. Society is about cooperation. Competition is relative, accidental, and cooperation is inevitable.
At the same time, the so-called evolution is not suitable for higher levels of wisdom such as thought or art. On the one hand, the development of civilization is spiral, not radical in a single line. It requires reflection and accumulation from time to time.
Even for the mind, returning or giving up is sometimes a choice after trying and judging. How can there be a single "evolution"?

His theory of evolution is used as much in our time.

It has made a leap forward in the thinking and understanding of mankind.
Evolutionary theory refers to the scientific conclusion that studies the development of life in the history of biology to expand the scope of adaptation and increase the room for survival (the anti-evolutionary view is that there is no evolution, no direction, and no conclusion in the history of biology, so another theory that does not contain Darwin's evolutionary ideas is propagated and named "evolutionary theory").

Dar Irwin's theory of evolution is also an anti-purpose theory of evolution. ()

Darwin's theory of natural selection has four main points: overbreeding, the struggle for survival (also called survival competition), heredity and variation, and survival of the fittest.
Species have the ability to overreproduce, but it would be more accurate to say that species are not at risk of extinction only if they are on a certain population size. So the explanation for this problem is that these creatures (who are not very competitive) overreproduce in order to maintain the continuity of the race.
In the process of life, every organism must fight against the natural environment, against the organisms of the same species, and against the organisms of different species, among which the struggle between organisms of the same species is the most intense; It is also believed that in nature, various organisms influence each other, restrict each other, and depend on each other.
Survival of the fittest means: in the struggle for survival, individuals with favorable variations are easy to win and survive in the struggle for survival. On the other hand, individuals with unfavorable mutations are prone to defeat and die in the struggle for survival.
That is to say, all the organisms that survive are adapted to the environment, and the organisms that are eliminated are not adapted to the environment, which is the survival of the fittest.
In the struggle for survival, the process of survival of the fittest and elimination of the unfit can be called natural selection, and the process of natural selection is a long-term, slow, and continuous process.
The reproduction rate of all organisms is increasing exponentially, and the number of offspring is quite staggering, but the number of biota is relatively stable, which indicates that only a few of the progeny of organisms can survive, and there must be a competition for resources. Darwin further deduced that the individuals of any species are different and there are variations, which may be neutral or may affect the ability to survive, resulting in strong or weak individual survival.
In the competition for survival, individuals with strong survivability can produce more offspring, the race can reproduce, and its genetic traits gradually gain an advantage in quantity, while individuals with weak viability are gradually eliminated, that is, the so-called "survival of the fittest", and as a result, the biological species gradually change due to adaptation to the environment. Darwin called this process natural selection.
In 1837, Darwin used a hypothetical tree to sketch the evolution of species for the first time. This concept soon became a hallmark of the theory of evolution by natural selection. But scientists now say Darwin's signature "evolutionary tree of life" showing the relationship of species in evolutionary history is wrong and needs to be replaced by a new theory. >>>More
What role did Darwin's theory of evolution play in restoring human face for the first time? The theory of evolution has always been a scientific book, and based on the above theory, it is possible to determine whether the restored face is in line with the environment at the time, and other facts, which plays a certain basic and auxiliary role in the restoration of the face. >>>More

Charles Darwin was an outstanding British biologist, and the two major theories he proposed for the theory of biological evolution were the theory of artificial selection and the theory of natural selection. 1. The theory of artificial selection: He believes that many of today's domestic animals and cultivated plants originated from wild taxa. >>>More
The steamer is right.
Moles live underground for a long time, the function of vision is not important, more to use hearing, touch, smell, therefore, hearing and touch and other developed, there will be more chance of survival, at the same time, due to the imbalance of development, in one place is strong, in another performance may be relatively weak, in the auditory performance is strong, but the visual performance may be worse. Therefore, when the generations are continuously screened by nature, the vast majority of those left behind are those with strong auditory, tactile, and olfactory abilities and relatively weak eyesight. >>>More
