We are told that the trouble for modern people is that they have been trying to separate themselves from nature. He sat high on top of a pile of polymer, glass and steel, dangling his legs and watching the tumbling life on this planet. According to this description, people have become a great lethality, while the earth is something weak, like bubbles curling up on the surface of a village pond, or like a group of delicate birds.
However, any idea that life on earth is fragile is an illusion. In fact, life on earth is the toughest membrane imaginable in the universe. It ignores the probability and can't let death cross. And we are the weak part of the membrane, as short and fragile as cilia.
Man is rooted in nature.
In recent years, biological science is making people take root in nature, which has become a fact that must be faced up to quickly. The new and difficult problem will be how to deal with the emerging concept that people are increasingly aware of: how human beings and nature are closely linked. The old idea that most of us once firmly grasped is that we have the privilege of dominating everything, and this idea is being fundamentally shaken.
Arguably, we are not a real entity, nor are we composed of our own more and more complex parts step by step as we have always imagined. We are shared, rented and occupied by other lives. Inside our cells, mitochondria drive cells, which provide energy for us to go out to meet every bright day through oxidation. Strictly speaking, they do not belong to us. It turns out that they are independent little creatures, descendants of the prokaryotic cells of the colonists who moved to us that year. It is very likely that some primitive bacteria poured into the ancient precursors of human eukaryotic cells and settled in them. Since then, they have kept themselves and their way of life, copied and propagated in their own way, and their DNA (deoxyribonucleic acid) and RNA (ribonucleic acid) are different from ours. They are our life forms, just like rhizobia of leguminous plants. Without them, we will not be able to move our muscles, tap our fingers and put forward ideas.
Mitochondria are stable and responsible guests in our bodies. I am willing to trust them. But what about some other small animals? What about those creatures that have settled in my cell in a similar way, those creatures that coordinate me, balance me and make my parts work together? My centriole, my matrix, and maybe many other unknown things that work in my cells all have their own special genomes, which are as strange and indispensable as aphids in the anthill. My cells are no longer pure entities that make me grow into an adult. They are more complex ecosystems than Jamaica Bay.
Of course, I like to think that they are working for me, and their every breath is breathing for me; But it is also possible that they walk in the local park every morning, feel my feelings, listen to my music and think about my thoughts?
However, I feel a little relieved, because I think those green plants are in the same boat with me. Without chloroplasts, they cannot be plants or green. It is these chloroplasts that run photosynthetic factories and produce oxygen for all of us to enjoy. But in fact, chloroplast is also an independent life, with its own genome and encoding its own genetic information.
A large amount of DNA carried in our nucleus may have come to us when the ancestors of cells merged and primitive creatures joined together in life. Our genome is a collection of instructions from all aspects of nature, coded to deal with all kinds of accidents. Personally, after mutation and speciation, I became the present species, for which I am naturally grateful. However, when no one told me these things a few years ago, I thought I was an independent entity. Now I can't think so. I don't think anyone can think so either.
The identity of life on earth is more surprising than its diversity. The reason for this identity is probably this: in the final analysis, we are all derived from a single cell. When the earth cooled, lightning revived this cell. It is from the offspring of this mother cell that we become who we are today. We still share the same genes with the life around us, and the similarity between grass enzyme and whale enzyme is the similarity passed from one species to another.
Viruses, which were originally regarded as the masters of disease and death, gradually showed the appearance of active genes. The evolution process is still an endless and boring biological poker game. Only winners can stay at the table and continue to play, but the rules of the game seem to be more flexible. We live in a series of dancing viruses, which, like bees, run from one creature to another, from plants to insects to mammals and back to me, and also run to the ocean, holding several such genomes, pulling several such genomes, transplanting DNA scions, and passing on genetic characteristics like handing food at a large banquet. They may be a mechanism that allows new and mutated DNA to spread most widely among us. If this is the case, then the strange viral disease that we must pay so much attention to in the medical field is also an accident and something has gone wrong.
I've been trying to think of the earth as a creature recently, but it's always meaningless. I can't think like that. It is too big and complicated, and many parts lack visible connections. One night the other day, when I was driving through the wooded mountains in southern New England, I thought about it again. If it doesn't look like a creature, then what does it look like and what does it look like most? Suddenly came up with an answer that satisfied me for a while: it is most like a single cell.
cell
I don't have a name.
Throughout the ages, those displayed in the historical cab
Occupy my name
-Inscription.
This is purgatory
This is the embryo of heaven I have ever seen.
I also mean to dedicate it to my only Xie Jing.
Let the embryo complete a division.
My language is a language that sounds everyday.
There is no Oracle connected to heaven.
This is not lightning, nor is it a sudden thunderstorm
In the sky of Wumeng, energy rolls far below the knee.
My language is the martyr of the people.
When the land meets the spring breeze again, it has primitive and powerful vitality.
Is desperate and fearless
The initial heart of reproduction on the time axis
It is an act of chasing and an understanding of suffering.
No matter how many mistakes and setbacks there are, they cannot be stopped.
Civilization will make this understanding into a specimen.
Stay in the nucleus, in the peptide chain of the gene.
Finally, take the right path.
I'm on my way to death.
Watching the comrades around him fall down one by one, dehydrated and rotting.
I couldn't help crying. They were broken down into another substance.
And this substance is gradually taking shape for the new era and new embryos.
Completely imperceptible
They are like a monument in a square.
no regret
immortal
