The impact of human scientific progress on the evolution of its own organisms

I think that human beings are gradually degrading, as you said, the retention of bad genes has greatly reduced the effect of natural selection, not only the population has increased, but there are more and more "monsters", and the evolution period of 5 million years cannot be escaped, and the injection of various vaccines has significantly reduced the immune system of human beings, so the body of Xin Chai (Mawangdui female corpse) is better than ours.

Mention a mistake.

Since it is "human evolution", the word "biology" can no longer be mentioned.

Is there a division between "living things" and "non-living things" in evolution?

I think it will have an impact.

Modern scientific progress has led to an increase in the birth rate and a significant reduction in the mortality rate.

The number of people on the planet has increased dramatically.

The natural environment is damaged.

This, in turn, upsets the balance of the ecosystem.

It also affects evolution.

But. Evolution is a slow process over a long period of time.

You don't have to worry about pulling!

I'm not worried, haha.

I guess so!!

Because disease is going to hit humanity.

Bringing the evolution of humanity to a standstill.

There is definitely an impact.

Good or bad, the truth will be known after a few years.

Judging from past experience, there is a high probability of bad.

Humanity has been self-righteous since the beginning of civilization, tirelessly destroying the planet and destroying the extremely complex and sustainable ecosystems that took hundreds of millions of years to form.

The destruction of forests, the misuse of resources, the pollution of the atmosphere, water.

SARS is gone, the avian flu is just a little bit, I don't know what else is coming.

People think that they are the smartest, but they don't know that they are part of nature, and if they don't conform to nature, they will be punished with destruction.

Heaven and earth are the mother, which can only be adapted, not transformed.

Question 1: Why did humans evolve and what caused it? Biological evolution is the process of adapting to the environment, generally speaking, from low to high, from simple to complex, referring to the good side.

Human evolution is a very long process, so if lz wants to know the details, I'll give you a **, this netizen's is quite comprehensive.

Going on, evolution is relative, for example, compared with modern humans and ape-man, in terms of technology and means of using tools and IQ, it is evolution, if it is said that in terms of survival ability and adaptability in the wild, it is degradation, so there is no all-round evolution, and evolution is accompanied by degradation. Human beings, like many species in the world, have evolved because we are not so perfect, and our bodies have not yet adapted to the environment.

Question 2: What is the cause and significance of human evolution? In order to better mate and reproduce.

Question 3: Why is the use of fire the most important step in the history of human evolution The biggest reason for the emergence of human civilization is because of the discovery of fire and the better knowledge of how to preserve it.

Fire enabled humans at that time to eat cooked food, resulting in more protein intake, and due to the full supplementation of protein, the human brain at that time was developed at a high speed; And because of the discovery of fire, humans at that time could also survive in colder climates (although some died); And with it, the human beings at that time had both a defensive function (most animals were afraid of fire), and also a hunting function, and they used the characteristics of animals to be afraid of fire and gradually drove the animals to the edge of the cliff and make them fall. Yamaho Toshi: So, humans at that time were able to catch more prey and get their own full nutrition

Question 4: What is the root cause of human evolution, evolution, development and change The root cause is genetic mutation.

Genetic mutations produce new genes, and the emergence of new genes leads to changes in gene frequencies, which in turn leads to biological evolution.

Question 5: What are the reasons for human development and evolution Human evolution originated from forest apes, and developed step by step from primates through a long evolutionary process. It has gone through four stages of ape man, primitive man, sapiens man, and modern man.

In the four stages of human development, the frequencies of genes in the gene pool are constantly changing", leading to human development and evolution.

The cause of biological evolution is a combination of genetic variation and natural selection.
