What were some of the life science discoveries that were not recognized at the time but were later c

That's some GMOs.

At first, it was definitely considered less important or denied, but now it is still more important, because paying attention to the various ingredients in it can be regarded as a major discovery in life science.

For example, Darwin's theory of evolution was ridiculed by all scientists at the time, they thought that Darwin was a molecule, and later Darwin's theory of evolution laid the foundation of biology.

For example, Darwin's species "The Theory of the Right to Live" is the survival of the fittest, which he was not recognized before, but now it is becoming more and more widely circulated.

The green fluorescent gene of jellyfish was not recognized by everyone at the time, and many people felt that it was meaningless and unrealistic, and it was not taken seriously until later.

At that time, microbial genes were not very important, but in fact, the study of microorganisms themselves was not very important before. With the development of science, microorganisms and their research are now highly valued.

For example, Darwin's proposal at that time was that natural selection for the survival of the fittest was not valued by people at the beginning, but later generations gave it to them and discovered it.

I think that the discovery of the Pekingese people is a very meaningful thing in our history, because the tree cave people are often not accepted by others.

The core of the theory of evolution is natural selection, the so-called natural selection, that is, life will randomly mutate to produce many manifestations of individuals, but nature will through the survival of the fittest, screening out the most adaptable to the environment through the survival of the fittest. In other words, the variation of life is untendented, and it is the natural inclined choice that determines the direction of the evolution of life. But in Darwin's time, the theory of evolution was not immediately accepted as truth, because it had a competitor, Lamarck, who put forward the idea that "living things come from evolution" in the era of creationism, which was equally great.

But Lamarck's theory of evolution is a far cry from Darwin's: the core of the theory of genetic acquisition is "use it and waste it": organs that are used regularly will be more developed, and those that are not used will degenerate.

For example, young trees will choose to grow taller in order to get sunlight; Giraffes want to make their necks longer and longer in order to eat the young leaves in high places; Fish in the deep sea do not need to see clearly, so the function of the eyes gradually becomes abandoned. <>

Martin Chalfie developed a method of using genetic recombination to place the GFP gene in the desired position so that it could be expressed in other organisms, and then published another extremely famous article in Science in 1994. The characteristic of GFP is that, unlike luciferase such as aequorin, GFP itself is a luminescent protein and emits light. Therefore, after reorganizing to the desired position, the organism can remain alive and be fluorescently labeled, which is very powerful, and GFP is no longer just a small role that accompanies the study of aequorin, but has become an excellent marker that can be expressed in various organisms and the effect is very intuitive (and cool).

So the excited everyone added a GFP expression to their research projects, and smashed out a bunch of luminescent organisms (by the way, a bunch of CNS**). <

The current consensus view of the origin of life is Darwinian evolution, because there is no conclusive evidence for other views, but there are many scientists who oppose this view. At this point, I despise the domestic education system, and treat evolution as if it were the truth, educating one generation after another.

I would like to recommend you a book written by an American, called "Critique of Darwin."

The current state of science and technology is simply unable to answer the profound question of the origin of life. A true scientist should always maintain a humble attitude, and they will appreciate the insignificance of man in front of nature.

Newton was religious in his later years, because he realized the greatness of nature and so little he could understand, so he attributed it to God.

Copernicus was sent to the execution ground and burned to death because the people of the time did not believe his theories and considered them fallacious. Copernicus's theory was finally proved correct.

Any theory, believed or disbelieved, is due to differences in their worldviews. And until the facts are confirmed, this theory will not be proven wrong just because no one believes him.

And the difficult topic of the birth of the universe and the origin of life is really possible!

We already know the origin of God, the highest life in the universe, from the "Universe Chapter", and from the "Human Chapter", we know the origin of life in higher space and the origin of human beings on the earth, and now let's take a look at the origin of tangible life on the earth.

There are many explanations in the scientific community about the origin of life on Earth, such as the origin of life from lipid molecules; Life originates from RNA; Life originated in the primordial ocean; Life originated on Venus; Life originated from deep-sea chimneys; Life comes from the earth's volcanoes; Life on Earth comes from outer space; The impact of a comet with water on Earth caused the origin of life; There is also the theory of terrestrial origin, the theory of natural occurrence, and so on.

Most of the above explanations make sense, because metaphytic life (microorganisms and fungi) is naturally produced on land, in the sea, in deep-sea chimneys, in volcanic areas, etc., not only in these special areas, but also in the soil, in the atmosphere, in the corpses of animals and plants, in rivers and ponds, in garbage heaps, trillions of lands are born, trillions of lands are born, and trillions of people die every day. No matter what the climatic conditions, as long as the elements of the natural environment change, there will be new species born immediately, so to speak, population growth, pollution of the natural environment, the intensification of the greenhouse effect, the expansion of the hole in the ozone layer, etc., will lead to the emergence of new species, and even large-scale outbreaks of new bacteria, these new astronomical new strains may alleviate the further deterioration of the ecology, and may also lead to a catastrophe for human beings, perhaps more severe than the "Black Death", not like the SARS virus to infect each other, It's about infecting trillions of people at the same time.

As long as there is a certain amount of humidity, the molecular structure of the soil will change and new life will be generated, which is how moss, lichens, and grasses come about.

The general process starts from the discovery of the problem and the question, and after the problem is found, make assumptions about the answer to the problem based on their existing knowledge and life experience Design the first plan, including the selection of materials, design methods and steps, etc. According to the **plan**, get the results, and then analyze whether the results are consistent with the assumptions, so as to draw conclusions Not all problems are ** to get the right conclusion at one time Sometimes due to the imperfect method of **, it is also possible to draw wrong conclusions, therefore, After reaching a conclusion, it is also necessary to reflect on the whole process

1) Through the analysis of the control experimental group set up by the biological group, it was found that there were two variables in the control experiment, one is light and the other is temperature In this way, when analyzing the experimental results, it cannot be explained that it is only caused by light Because temperature is also a variable, it may also be caused by temperature, and the experiment is not convincing Therefore, there should be only one variable for the effect of light on the germination of peas, that is: light

2) The two basic principles of experimental design are the "control principle" and the "only variable principle" Control experiment: When studying the effect of one condition on the research subject, the experiment is carried out under the same conditions except for this different condition where the different conditions are the experimental variables

3) When conducting experiments on the effect of light on pea sprouts, the number of peas used should be large, because this can reduce the error caused by the influence of other factors

So the answer is: question, hypothesis, plan, plan, conclusion.
