In the early days of the earth's formation, there was no water and oxygen that life depended on, and at that time, ultraviolet rays hit the earth directly, and the air was full of highly toxic substances, so there was no possibility of living things. Over time, primordial oceans were formed on Earth (as for how oceans were formed, there is no absolute certainty), and primordial oceans gave birth to single-celled organisms, or bacteria, the progenitor of all living things. And then there were hundreds of millions of years of reproduction and evolution, forming such a vibrant earth.
Therefore, when the earth changes and becomes more suitable for the existence of living beings, a colorful biological world will be born.

What is the concept of living beings.
A living thing is a collection of objects whose elements include: a living object with the ability to survive and reproduce produced by chemical reactions under natural conditions, and a living offspring produced by it (or them) through reproduction.
So you should think clearly about why you are conscious.
There is awareness. After the concept.
There are creatures. In fact, the world is a sort of combination.
Sorting has a concept.
And there are creatures.
So biology is a sorting.

When the earth was formed, during violent geological movements, methane, water vapor and other gases were reflected and released.
Earth's gravitational pull. Rotation and revolution. Firmly grasped a part of the (primitive atmosphere).The environment was extreme - volcanic.

Strong (promotes mutation), thunder and lightning (promotes synthesis).At the same time there are a large number of .
Amino acid. The material conditions of life).Amino acids do not need to be combined under extreme conditions (chemically conditional, of course).
A very small fraction of them accidentally form primitive RNAs with rudimentary life characteristics(Now there are experiments that have done it; A glass sphere is filled with methane and other gases (simulating the original atmosphere) and a large amount of amino acids are added in an environment of continuous discharge. Synthetic raw RNA!!
Raw RNA can combine amino acids to form complex RNAOver the long years, RNA - DNA - active proteins (initial life) - even longer years - single cells.

I thought that countless particles of matter interact with each other, and there are various modes of interaction. (Lao Tzu said that one life is two, two is three, and three is everything.) )
And among them, there must be a pattern, the orderly movement of material particles, and this mode of motion can appear in cycles! (This is the most essential nature of what we call "life.") Because this pattern of material movement can be spontaneously reproduced, it can be developed, complicated, and even developed in different directions on this basis.
So it evolved to the present, and a rich and colorful biological world has been formed.
PS: It's not uncommon for loops of movement patterns to appear, and there are similar situations in various fields. )
But why are only living creatures? That's because the mode of action of other particles of matter cannot reproduce their own motion, so although it happens countless times in nature, it is not accumulated at all, and it will always remain in its original state.
In fact, the movement mode of matter particles that developed into living beings was not much different from other material particle motion modes in the beginning. It's just that it has the characteristics of retaining itself and improving itself, so that its movement mode can continue to be complex and enriched, and after an extremely long time, it finally shows a different state.
In this sense, life is about inheritance and development. Broadly speaking, everything that can be inherited and developed is life. And life on our planet is only the only type of manifestation we see. In the vast universe, there may be many life forms that are fundamentally different from ours based on chemistry.
As for many of the conclusions now, they are hindsight, just stating some facts, and the explanation of the matter itself has no meaning.
The explanation is more abstract, I hope you can understand, if you don't understand something, you can send me a message.
evolved over a long period of time.
Haha, from a philosophical point of view: all living beings in the world live to consider what they live for? (except for those that can't be considered).
What is love? The meaning of love is very broad and can be friendship, family affection, love, ......Perhaps the most interesting thing for people is love, right? Then I might as well talk about love. >>>More
When the earth was formed, the earth was a dead ball, that is, there was no living object, this issue is also very controversial in our academic circles, I am more in favor of comets transmitting inorganic matter and objects that make up living things, such as chlorinated polyvinyl chloride and other substances (this is very mysterious, it is still a mystery), why comets have such objects, if you are interested, you can see other people's opinions, comets are like messengers that spread life, waiting for further study by you young people. >>>More
