The most primitive theory is that microorganisms evolved first.
-
Human evolution originated from forest apes, and evolved step by step from primates through a long evolutionary process.
Theoretically, the process of human origin is divided into three stages: the stage of Australopithecus, the stage of man and ape, and the stage of man who can make tools.
Due to the development of archaeology, prehistoric civilization has been gradually denied, and archaeology has most of the evolved hominin fossils. In conjunction with the discoveries of modern biology, it was discovered that genetic DNA is evolutionary, confirming the authenticity of the theory of neutral evolution.

I think dear landlord.
Glad to analyze for you.
I've had your problem before.
Hope it can help the landlord.
People live to experience joys and sorrows, birth, old age, sickness and death, in order to understand what people live for?
In order to realize their own ideals, pursuits, goals, desires and values.
It's tiring, it's hard.
Because society is very unfair, it is very helpless to live.
If you are sad and sad, you have to cry, and if you find something to do, you will not be bored.
Because that's how life is.
No one's life is smooth sailing.
As long as you work hard, it's wonderful!
Be optimistic about anything.
Keep a normal heart.
Life is inevitably about falling and waiting.
Be brave enough to look up.
The sun is always after the storm!
I'll give you advice, can you see it?
1.Look at the world with another eye, not everyone in this world is very smooth, just look at how you solve it, for example, you were hit by someone when you were walking, others apologized to you, sometimes you still feel very angry, but you didn't expect that the person who hit you was actually more uncomfortable than you, or think about the sentence "Happy is also a day, unhappy is also a day, why not be happy every day".
2.If you think that you are in a bad mood, you will be in a bad mood, then you don't need to think about it, if you still want to, then keep yourself busy, let yourself have no time to think about it, let yourself live every minute to the fullest, and then don't fall in love with the bed after waking up in the morning, get up when you wake up, get busy, open the window, breathe in the fresh morning air, relax your whole body, and let yourself imagine a happy little angel ......
3.Choose a place with fresh air, quiet surroundings, soft light, undisturbed and free movement, and take a position that you feel comfortable in, standing, sitting or lying down.
4.Move some large joints and muscles of the body, the speed should be even and slow when doing it, and the action does not need to have a certain format, as long as you feel the joints let go and the muscles relax.
5.Take a deep breath, inhale slowly and exhale slowly, saying "relax" in your mind whenever you exhale.
6.Focus your attention on some everyday objects. For example, look at a flower, a little candlelight, or anything soft and beautiful, and look closely at its subtleties. Light some spices and inhale the aroma of it.
7.Close your eyes and try to imagine some tranquil and beautiful scenes, such as blue waters, golden sandy beaches, white clouds, mountains and water.
8.Do activities that you enjoy that have nothing to do with the specific things at hand. For example, swimming, taking a hot bath, shopping, listening, watching TV, etc.
9.Life is easy, life is easy, life is not easy. Don't worry, there are a lot of people in this society who are almost like you, but they are all living happily, not everyone can succeed, as long as you work hard to treat everything, take life seriously, as long as you take every day seriously, no matter how your life is, I believe it is wonderful.
The landlord is welcome to continue to ask.
Please forgive me for any inaccuracies!
Looking forward to your adoption !!

After the creation of the earth, a large number of single-celled lifeforms were naturally produced under certain conditions, and these single-celled lifeforms continued to evolve under various conditions, one of which formed a human being, and modern humans are cellular.

Man is a rat become, and the DNA of rat and man is the closest. Yellow people are yellow rats, and Caucasians are white rats. That's why humans experimented with mice.
That's why the 12 zodiac rats are number one. Some people may say it's a fallacy, but I tell you that it may be true.

Our earliest ancestors were dinosaurs, and then slowly evolved into apes, and the closest ancestors to us humans are apes. So we're apes too!
-
As far as I know, man evolved from an ape.

From stupid monkeys to intelligent monkeys, from intelligent monkeys to apes, from apes to apes, from apes to humans.
-
Humans evolved from single-celled organisms to multicellular organisms, from multicellular organisms to marine animals, from marine animals to amphibians, and finally mammals.
Man evolved from the mammalian species of Apeidae.

Regarding the origin of human beings, there are three theories: creationism, extraterrestrial creationism, and evolution. Creationism holds that the origin of the universe, the origin of life, and the emergence of human beings were all created and designed by God or some supernatural force, and that human beings were created by God in his own form. Extraterrestrial creationism holds that human beings were created in prehistoric times by extraterrestrial intelligent beings or ancient astronauts.
The theory of evolution is a theory first proposed by Charles Darwin and gradually developed, which believes that human beings originated from apes, and human beings developed step by step from primates through a long evolutionary process. This article will only discuss the origin of humanity from the evolutionary aspect.
Humans, undoubtedly the most intelligent animals on earth, we know that we originated from apes, millions of years ago, we were apes, living in Africa!

What is it that makes human beings? In a biological sense, man is an animal, and man belongs to the class of Mammals, Primates, Hominidae, and Hominis. The ape is evolutionarily related to man and hence it can be said that it is the ancestor of man.
About 203,000,000 years ago, humans appeared on Earth. Humans were transformed from Australopithecus. But apes and humans are very young in evolutionary history, and if the current age of the earth is 12 hours, then the lifespan of man is less than half a minute.
The scientific theory of human origins began with Lamarck in the 18th century and began to be formed by Darwin. In antiquity and before the 18th century, only a few guesses could be made about the origin of man. Although ancient biologists pointed out the structural similarities between humans and animals, they could not come up with any systematic theories to explain the mystery of human origins.

Humans evolved from forest apes, which and all mammals, reptiles, and amphibians all evolved from the landing of some kind of total-finned fish, and fish gradually evolved from the earliest single-celled animals.

Human memory ability is essentially the ability to store information and give feedback to the brain. The human brain is mainly composed of nerve cells, and the edges of each nerve cell have a number of outward protruding parts, called dendrites and axons. At the end of the axon there is a bulging protrusion called a synaptosome. >>>More
