According to Darwin s theory of evolution, how can a snake grow feet and horns? 20

Darwin's theory of evolution was wrong.

First, natural selection cannot be identified at the genetic level, and natural selection can only select traits of organisms. Genetic changes, or mutations, that are reflected in biological traits, require considerable accumulation, and natural selection cannot be recognized.

Second, according to the above, the role of natural selection is that it can select gene combinations, not gene mutations. For example, if we mark the back of a deck of cards, and the player can choose the cards they want in turn, then playing Texas Hold'em and playing landlord will definitely not be the same cards. But no matter how different, this card is still a deck of cards, but the combination of cards is different, but there is no new card, will not be because of the play of the landlord, there will be an extra 2.

Therefore, people in Darwin's time did not understand genetics, and Darwin's theory of evolution was just describing different combinations of genes to adapt to different environments. But in any case, evolution, which refers to the production of genetic information with new functions, has been proven to exist so far.

Suppose it is possible that one of the snakes in the snake group suddenly grows horns, and then the snake has a natural predator that needs horns to fight, then the horn gene will continue. Also, stronger or more aggressive horns will survive better.

Evolution lacks animal fossil evidence, and no fossils have been found in the middle of evolution.

As long as there is no physical evidence of the evolutionary process, the mystery cannot be completely solved, and Darwinian evolution is incomplete.

Natural selection, if the environment requires it to grow feet and feet, then its genetic mutation will develop towards feet and horns, and it will take time.

Go back to the era of small molecules.

Did snakes evolve venom that they could control on their own? No, biological evolution has no clear direction and is not controlled by biological consciousness. The evolution of snakes is based on changes in the genetic frequency of the population (according to the current scientific theory, all organisms evolve in this way), and the change of gene frequency cannot be controlled by snakes, and snakes are only a species that has gradually developed into modern times by adapting to the environment.

According to the modern theory of biological evolution, snakes must have a variety of mutant genes, some genes enable snakes to secrete venom, and the way snakes prey makes snake venom a reliable way, conducive to snake predation, some eat to survive, in order to continue to pass on the relevant genes, gradually,As the frequency of snake venom genes increases in snake populations, venom-possessed snakes become prevalent in the corresponding snake populations.

However, this is not absolute, and modern scientists have also found that some species of snakes occasionally appear in individuals that cannot secrete venom, and they return to animals that use speed and hunting skills to huntThese very few non-venomous individuals in venomous snakes are also the product of evolution, due to genetic reasons, so do snakes have a choice in this case?

There is still no, what kind of genes the snake Lao Tzu passed on to it, what kind of traits they have. Using the theory of evolution to explain snake venom is only to be viewed from the point of view of "natural selection", and why there is a snake venom gene in the gene pool of the snake population, the answer can only be "accidental", and the gene mutation is random, no one can explain. Snakes do not only live on venom, there are also many larger snakes, that is, low body temperature, camouflage all over the body surface, rely on ambush and then raid the prey, entangle the prey to suffocate to death, and then swallow it calmly.

Because this is the result of biological evolution, not all snakes can evolve venom.

Other snakes will evolve other aspects as well, and they don't have to evolve venom.

There are also many types of snakes, some without venom, but they have evolved muscles.

I think this is mainly due to genes, so I didn't evolve Venom.

Snakes have venom! This must have evolved from this, and the direction of evolution is also different.

Darwin's theory of evolution and common sense are often contradictory and cannot be explained.

This is mainly because they can rely on other methods to save their lives.

In the process of evolution, each animal lived in a different environment, so it will be like this.

Because this thing is different for every creature, that's why it's like this.

(1) The forelimbs and necks of ancient giraffes were some long and some were short, and the reason for the above individual differences was that the ancestors of giraffes produced (

variation). 2) In the course of evolution, individuals with long necks and forelimbs were retained, while individuals with short necks and forelimbs were eliminated due to (

Survival of the fittest. (3) Food plays a role in determining the survival and elimination of giraffe mutants.

4) In the process of evolution, individuals with long necks and forelimbs were gradually preserved, indicating that such individuals were in tune with changes in their environment (

adaptation). 5) The surviving individuals are through (

heredity) to accumulate traits.

6) Modern giraffes are by (

Fittest. Natural selection and genetic accumulation are formed gradually.

In high school biology, Darwin's theory of biological evolution can be reduced to three processes:1Overbreeding. 2.Struggle for survival. 3.Survival of the fittest.

The evolutionary hypothesis has become the mainstream view of human origins, and although most people believe in the evolutionary explanation of human origins, it is still questioned by many because of the lack of critical evidence.

Evolution is overturned by theology. In science, however, there is no new theory that can systematically and comprehensively replace the theory of evolution into a more scientific genus theory. Except for theology* After all, theology can explain everything.

Therefore, many great scientists usually get close to theology and philosophy in the later period to maintain their lifelong research, which is normal. Since you can't be a person who studies science or studies theology. It depends on what you believe.

No, although some of the views of Darwin's theory of evolution are somewhat contrary to some views of modern biology, there are still many things that are worthy of our desirability and worthy of deep thought and admiration, so Darwin's theory of evolution is still in the process of being revised and improved.

It has long been disproved, and the theory of evolution, like other theories invented by man, has long been overturned, and perhaps it can be said that the theory of evolution is the biggest lie of the 18th century.

Nope! Because biology majors still use evolution as the basic theory, don't you believe to see which country's biology has talked about creationism as a science?

No. It is supplemented by later generations, and there is a difference.

When I first started studying biology, I didn't believe that humans evolved from apes. Looking back now, I was very tolerant of this statement from the bottom of my heart!

I'm not afraid to tell you, I've seen gui before, maybe it's because the eye of the sky is closed relatively late, and it is generally invisible after the age of 3, of course, the memory of the age of 3 is very unreliable! It is also possible that the body was relatively weak at the time, and I saw it when I was in elementary school! And to be sure, it's not an illusion!

And then I have a relative who works in the hospital, and I have seen it!

So I don't agree with a lot of what materialism says, of course, it's just a materialist interpretation of those parts that go beyond the realm of matter. Including the term human evolution! Since there is a GUI, then it shows a problem, God should also exist!

No is still used but has been added.

With the rapid development of human beings, the scientific and technological civilization of human beings has undergone tremendous development, the material density of human beings has increased several times, the sensitivity of human sensory tubes has increased by more than 100 times, and the strength has increased by 1000 times. Survival, health, and intelligence have also increased thousands of times, and life expectancy will be extended to "long live", and mass migration can also change the direction of genetic development. If humans colonize the universe beyond Earth, it can create the perfect conditions for Darwin's evolution.

People will eventually see various changes in the future. This is determined by the environment of the colonial planet and the characteristics of human existence.

According to Darwinian evolution, humanity should look better and better next, and then eventually perish. Of course, Darwinian evolution wasn't necessarily entirely correct.

What will become of human beings next, we can't do it, and we can't get it, because evolution still needs to take into account the surrounding environment.

According to Darwin's theory of evolution, humans will evolve to have long legs, long arms, and big eyes, but this is unrealistic.

No matter how man evolves, he will still be human. Human beings may have the following aspects of development, one is that the child will get taller and taller, the second is that the weight will become heavier and heavier, the third is that the brain capacity will become larger and larger, the fourth is that the wisdom will be higher and higher, and the fifth is that the social survival system will be better and better.

According to Darwin's theory of evolution, people will not evolve into any other species, but may adjust their physical state according to the environment.

According to Darwin's theory of evolution, human beings will eventually evolve a ball, after all, human weight is gradually increasing, but in our own definition, we are still human.

The evolution of human beings will also be endless, manifested in the development and evolution of human IQ and improvement, but evolution is a long process, and major changes will not occur soon. With the advancement of human science and technology, it is also possible for human beings to change some of their existing characteristics and lifestyles in order to better adapt to the universe and the natural environment, and to evolve for a higher quality of life, this is certain.

There are scientific explanations for the human soul, and different people have different scientific explanations, atoms, molecules, particles, or higher, and I heard that there are high-tech captures.

Darwin's theory of evolution has been constantly doubted since its inception, and many people today deny that man evolved from ape-man.

But, in any case, the question in the title is premised on the correctness of Darwin's theory of evolution.

After millions of years of evolution, human beings have become completely different from apes inside and out, including their living habits.

Have humans evolved to the extreme? Or what else is the possibility of evolution?

The so-called evolution is the result of the interaction between the living environment and one's own adaptation. The transition from crawling on all fours to standing on two feet is the result of an adaptive change. If the size of the soles of a person's feet and the structure of the tripod remain the same, it is impossible to stand up at all.

In this process, the natural environment has not changed much, and the way of human life and activities is slowly changing in adapting to the new way of life.

If changes in lifestyles and living environments are the main causes of biological evolution, the same logic applies to the current evolution of human beings. Compared with more than 100 years ago, human life has many more intelligent and automated tools or equipment. So it is thought that the evolution of human beings is likely to be as follows:

1. Hair loss. This is related to frequent contact with electronic products.

2. Decreased physical fitness. When life is good, the work that requires people to do manual labor is slowly mechanized, and if there is less labor, people's physical fitness will naturally decline.

3. Brain capacity enlargement. In the future, more and more knowledge will be needed, and people's brains will also be upgraded.

4. Vision deterioration. This is also related to the fact that people frequently look at electronic products such as mobile phones, and myopia will be seen everywhere in the future.

5. Skeleton changes. Since people are still mainly sitting, the bones of the human body will also adapt to this need. The spine will become strong and adaptable to the load that prolonged sitting puts on the body.

Darwin's theory of evolution was controversial? Did humans really evolve from ape-man?

There is no clear answer, the main point of Darwin's theory of evolution is the survival of the fittest, how the earth will change in the future, human beings will adapt to evolution, whether the evolution of the mind or the evolution of the limbs is prominent, it depends on the influence of the environment.

Darwin's theories were limited.

The correct theory is that man will evolve into a spherical shape, then a smaller and smaller spherical shape, then a metamorphosis (a change at will), and finally an intangible.

People are getting smaller and smaller, their heads are getting bigger and bigger, their strength is getting smaller and smaller, and their IQ is getting higher and higher!

Please, you're outdated.

Evolutionary ethics have been justified and are wrong.

A weak person with a smart mind and weak limbs.
