Question 1: What does it mean to use our brains as a metaphor? If we use them often, we will become more flexible and slow when we don't use them.

Question 2: throw it away after use, or throw it away after use. Which is the idiom? Use and abandonment

The idea of "use in and discard in retreat" was first put forward by the French biologist Lamarck, who systematically expounded his evolution theory in Animal Philosophy (later called "Lamarck Theory") and put forward two rules: first, use in and discard in retreat; One is acquired inheritance. It is considered that both of them are the causes of variation and the process of adaptation. He proposed that species can be changed, and the stability of species has only relative significance. The reason of biological evolution is the direct influence of environmental conditions on biological organism. It is believed that under the direct influence of the new environment, the habits of living things have changed, some commonly used organs have grown, and those that are not commonly used have gradually degenerated. People think that adaptation is the main process of biological evolution.

Question 3: Teachers, a popular word on the Internet is "tired, abandoned and retired". I'm confused. I hope you can give me advice: under the direct influence of the new environment, the habits of living things have changed, some frequently used organs have grown, and those that are not often used have gradually deteriorated.

Question 4: Is there any contradiction between the theory of evolution and the theory of exhaustion? Based on the theory of abandonment, it is believed that under the direct influence of the new environment, the habits of organisms have changed, some frequently used organs have grown, and those that are not often used have gradually deteriorated. These changes can even be inherited.

The outline of Darwin's evolution is natural selection: a "long" neck deer with a short neck can't eat the leaves on a tall tree and starve to death. Giraffes with long necks can survive. Reproduction. Maybe the gene with a long neck is recessive, so giraffes will have a short neck and starve to death. There is no chance of reproduction. Generation after generation, dominant and recessive short neck gene carriers are selected by natural selection.

The theory of evolution and the theory of use are contradictory.

Darwin's theory is to overthrow the theory of use, use and abandonment (of course, this is not his purpose).

Please don't think that overthrowing Darwin means overthrowing Darwin.

Overthrowing the use, advancing and abolishing, just proves Darwin.

Question 5: What are acquired inheritance and failure? To talk about acquired inheritance, let's talk about acquired inheritance first.

Acquired traits, also known as acquired traits, refer to certain variations in morphology or physiological functions during the growth and development of organisms due to the influence of external conditions. Simply put, it is a trait acquired by an organism after birth.

Generally speaking, acquired traits cannot be inherited. However, some scholars (such as Lamarck) believe that acquired traits may become heritable if they encounter corresponding genetic changes (such as mutations). This is inherited.

It is a basic principle of life movement to use it and discard it.

The so-called use means that the human body does work in a state of super-balance. The so-called waste is to make the human body in a relatively leisure state by doing low-balance work. When we use it and waste it, it means that when the human body does a super-balanced job, the corresponding parts and functions will grow; When the human body does low-balance work, the corresponding parts and functions will disappear.

It is another way of saying that human function must be balanced by doing work, and it is also the internal reason why human body can adapt to environmental changes.

It should be noted that the utilization of waste should be moderate (that is, it must be kept in an appropriate state of over-balance) in order to make the corresponding parts and functions grow. If you use it too much (that is, you do too much work beyond the balance), it will cause excessive fatigue and damage to the cells in the user's body. Therefore, not only will it not be used, but it will also be used back, leading to destructive consumption of the body and even death.

Question 6: Why do so many people think that the idea of "fishing with exhausted resources" is completely wrong? I think it is appropriate to abandon it under certain conditions. For example, we often say that it is positive as a philosophical point of view, but because of the cognitive level at that time, it is wrong to regard it as a theory of biological evolution. From the perspective of modern genetics, there is a central law in genetics. Information can enter protein from DNA, but it cannot flow back to DNA from protein. DNA can be understood as the information needed to construct protein ―― protein's formula, and protein is the substance that constitutes and sustains life. This means that an organism cannot write the information it has experienced into DNA, so the characteristics obtained by using it and discarding it cannot be passed on to the next generation. That is, acquired inheritance is unscientific.

The idea of "using in and discarding in return" was first put forward by the French biologist Lamarck, who systematically expounded his theory of evolution in the Philosophy of Zoology (later called "Lamarck's theory") and put forward two rules: first, using in and discarding in return; One is acquired inheritance. It is considered that both of them are the causes of variation and the process of adaptation. He proposed that species can be changed, and the stability of species has only relative significance. The reason of biological evolution is the direct influence of environmental conditions on biological organism. It is believed that under the direct influence of the new environment, the habits of living things have changed, some commonly used organs have grown, and those that are not commonly used have gradually degenerated. It is believed that a species can gradually become a new species by constantly strengthening and perfecting its adaptive traits, and these acquired traits can be passed on to future generations, thus making organisms gradually evolve. People think that adaptation is the main process of biological evolution. For the first time, he discussed the motive force of biological evolution from the relationship between biology and environment, which provided a certain theoretical basis for the emergence of Darwin's theory of evolution. However, due to the limitation of production level and scientific level at that time, Lamarck oversimplified the process of the direct effect of environment on organisms and the inheritance of acquired traits to future generations when explaining the reasons for evolution, which became an inference without scientific basis, and mistakenly believed that organisms were born with an upward trend, and the will and desire of animals also played a role in evolution. Darwin didn't completely agree with him.

Question 7: Will it be returned after use or will it be discarded after use? Thank you. There is no need to raise simple things to the philosophical level. "Use into waste and retreat" is relative to the evolutionary history of biology, and "use into waste and retreat" is not used to describe individuals.

The problem is simple, that is, for your knees, you are doing too much exercise at present. You should have a rest and even check whether your knee will be hurt.
