According to Darwin's theory of evolution, all life is evolved from an ancestral life, and as long as it can reproduce and reproduce, it can be called life. The generation of life is caused by the mutation of genes again and again, and through natural selection to remove genes that are not conducive to the reproduction of the race, one gene is not necessarily beneficial to the individual, but it must be beneficial to the whole race, so reproduction can be said to be the meaning of life. How the first ancestral species was born is still inconclusive.
Of course, genetic drift is also a form of evolution, and unlike natural selection, it has the potential to leave behind neutral genes that are harmful to the individual.

From a biological point of view, life is a cell-based monomer or cell complex. The basic attribute of life is the process of forming a spontaneous movement form through the exchange of energy with nature. The process from generation to end is the manifestation of life, the result of the movement of matter, and the product of natural induction, which is different from the general form of material movement.

Life is an integral part of living organisms, the nature and ability of survival and development of living organisms, the consciousness of survival and development manifested by the growth, reproduction, metabolism, stress, evolution, movement and behavior of living beings, and the concrete and abstract things that human beings discover, define, manifest and extract from living organisms through cognitive and practical activities.

Life is a living body, it is the vitality of survival, everything lies in movement, there is the possibility of life, and there are also situations that are not suitable for self-disappearance or elimination. As for human life, it comes from the physiological cooperation between men and women, the crystallization of bone and blood, and the human will is the life force, the body is the life possession, the meridian pulse, and the heart activates life.

My research proves that the living body (not the soul) is an eternal existence, without birth and death, without beginning and end, it is the original existence, life is the unity of the three conditions and the combination, that is, the life body, the body, and the consciousness, the three conditions are combined and the unity of life exists, the three conditions are separated, the first period of life ends, after the death of the body, the life body and consciousness immediately enter the next life cycle and the cycle does not stop, the three conditions of life cannot function independently and cannot exist independently, To put it simply, life does not exist for a lifetime, it does not evolve, it is not created by God.

What is life? Life is the soul of nature, the essence of nature, and the ultimate evolution of nature, a higher form of matter. To live is to be alive, to be a state of being.
When it comes to what life is, people often answer the wrong questions and talk about some meaning of life inexplicably, in fact, life is life. In biological evolution, life comes into being from nothing, from low to high, and even from small to large to aging, which is the inevitable process of life evolution.

Individual life refers to the physical body of an individual, the process of an individual (incarnation) from birth to death, and is used to manifest and display to people as a reference framework. The life of an individual makes his contribution to the evolution of the earth as a whole or the universe (whatever he does has reference value is a contribution).
-
As the name suggests, life has a process of gestation, and life is a process with a time limit. Then life exists for a period of time after it is generated, and we say that it is alive.
-
Life is a process of birth, growth, aging, and death, and the higher life has intentions and thoughts, which can serve other lives and material things. Since the spiritual leap of life, the world has entered a new level, but it still cannot escape the law of birth, old age, sickness and death!

Life is like fire, the same essence as the fire caused by the sun scorching the earth, without life, our earth is a scorched earth, meaningless, life is standing up tremblingly on this scorched earth, staggering farther and farther.

Life is the mode of existence of proteosomes, and this mode of existence essentially lies in the continuous self-renewal of the chemical components of these proteosomes", I think Engels's explanation of life should be more convincing.

Life affects lifeTo put it simply, one person affects another person, and one living being affects another living being. "Life affects life" is a cultural concept proposed and created by the official website of Pacific Direct Purchase. Designed to:Influencing another life through an individual's life not only reflects a "people-oriented" thinking, but also ultimately realizes the creation of self-worth and social value.
How to embody the meaning and value of life is a key issue. In the process of the operation of the living body, the struggle, effort, morality, and realm that will be formed will be spread with sincerity, love, and helping mentality, and it is the behavior of another living body that is influenced by the living body.
As Bing Xin said, "My whole life and all my energy have been devoted to the struggle for the liberation of mankind, the most magnificent cause in the world." ”
The value of life is embodied:
Meaning and value are given by people. The meaning of life is the same. What kind of meaning people give to a thing, it has what kind of meaning.
Throughout the ages, people have given high meaning and value to life, so many fine traditional virtues have been derived, such as "governing the country".
Such as: loyal to the country, diligent and loving the people, impartial law enforcement, courageous, helping others, fair, polite and humble, fair trade, respect for teachers and education, diligence and dedication, saving lives and helping the wounded, etc.; To the "Qi family", such as: equality between men and women, harmony between husband and wife, brothers, friends and brothers, diligence and thrift, neighborhood unity, etc.; And then to "slimming", such as:
Ambitious, honest and trustworthy, upright, self-improvement, morality, self-discipline, self-cultivation, etc.
Therefore, the value of life is the formation of a moral character, a realm of doing things for others, a realm of struggle, a kind of successful detachment, and a kind of selfless dedication.
Mr. Shi Tiesheng once said: The meaning of life lies in being able to create the beauty and wonder of this process, the value of life lies in being able to appreciate the beauty and tragedy of this process calmly and excitedly, and the true meaning of life is to be able to enjoy the sweet and sour and bitter ...... of this processAnd all the results of formation are formed through the process of people influencing life with their lives.

Life science is a science that studies the phenomena of life and their operating laws, and it studies the phenomena and essence of various life activities, the relationship between organisms and organisms, and the relationship between organisms and the environment.
In 1896, a Swiss doctor named Friedrich Michel was the first to isolate DNA and change the worldview of human understanding of the world. Phenomena that once did not understand the cause can be described by science. For example, the causes of people's emotions, the reasons for people's specific actions in specific environments, and other phenomena can be explained.
With the rapid development of life sciences, diseases that were once impossible now have a way to come. The causes of human aging have been studied, and it is possible that people will not age by some means in the future. The composition of the complex human system and the operation of tiny cells, the reproductive and development mode of viruses, the pathogenesis of cancer, etc.
With the development of life sciences, they will be stripped of their mysteries.
However, the development of life sciences will also have disadvantages to human beings, such as some human actions are caused by certain hormones of the human body, which may require their own willpower to overcome in the past, so as to reduce the number of occurrences, and restraint is the ability to change generated in the process of human evolution. Now, with the development of life science, if you want to restrain this behavior, you can inject the corresponding hormones to avoid this problem physiologically. However, by injecting hormones, there is an effect on the organs that work together.
With the development of life sciences, which affect people's way of thinking, such as the development of ecology promotes people's holistic thinking, with the development of brain science, bioscience technology will help improve human thinking.
The impact on the ethical and moral system of human society, such as IVF, organ transplantation, artificial modification of human genes, etc., will challenge the existing ethical and moral system of human society. The mass production of genetically modified organisms (GMOs) in the natural gene pool of modified species may affect the stability of the biosphere.

Life science is a science that studies the nature, characteristics, occurrence and development laws of life phenomena and life activities, as well as the interrelationship between various biological rights and between organisms and the environment. It is used to effectively control the return of life activities, actively transform the biological world, and benefit human life, which is closely related to human survival, people's health, economic construction and social development.
While focusing on the cultivation of logical thinking, the discipline of biology also has unique complexity, flexibility, holistic and systematic thinking, which is conducive to students' objective view of the life world and is conducive to students' social adaptation.

Life science is the science that systematically expounds on major issues related to the nature of life. The laws of physics and chemistry that govern the inanimate world also apply to the living world, and there is no need to give a mysterious vitality to living matter. Life science research relies not only on physical and chemical knowledge, but also on the instruments provided by the latter, such as optical and electron microscopes, protein electrophoresis instruments, ultracentrifuges, nuclear magnetic resonance spectrometers, positron emission tomography scanners, and so on.
Life scientists are also drawn from a variety of disciplines. The cross-penetration of disciplines has led to many promising growth points and emerging disciplines.
