1 point 2
2 minutes 4
4 minutes and 8 seconds ... infinitely divided, and infinitely many single cells were born.
Here is something worth thinking about: even if it splits, it is still the same single cell. Why did it evolve into various creatures?
That's because divided single cells absorb different substances and impurities (food sources), leading to variation. Mutated single cells recombine with other cells to produce new species. (hybridization stage)
The distance between cells is too close, and there is no regular movement, that is, chaotic phase, hybridization and recombination, forming various species.
Then why didn't later species cross and recombine?
This question is simple: because later species have their own ethnic groups (you can imagine it as a civilized period, just as humans don't find animals as companions, in the same way. ), with territory, it won't be as chaotic as the cellular stage.
Origin of species: by splitting themselves, constantly copying more of themselves, evolving groups from individuals and expanding the scope of life.
Species will evolve, and new species will be formed after the accumulation of gene and phenotype mutations.
Microorganisms are the earliest "inhabitants" on the earth. If the history of the earth's evolution to today is condensed into one day, and the birth of the earth is zero within 24 hours, then the first inhabitants of the earth-anaerobic heterotrophic bacteria were born at 7 am; At about 13 in the afternoon, aerobic heterotrophic bacteria appeared; Fish and terrestrial plants are produced at 22 o'clock at night; And humans will not appear until the last moment of the day.
In nature, there is a large class of people whose tiny lives are invisible to the naked eye. Whether it is a bustling modern city, a rich and vast field, a rare mountain peak or a vast ocean, there are traces of them everywhere. These tiny "residents" are called microbes, and together with animals and plants, they form a biological army, which makes nature look full of vitality. The microbial kingdom is a real "lilliputian country", where the "subjects" belong to several representative families, such as bacteria, actinomycetes, fungi, viruses, viroids, rickettsia, chlamydia and mycoplasma.
As far as members of the bacterial family are concerned, they reproduce through their own division. As long as the conditions are right, it can be divided once every 20 minutes, divided into two, divided into four, divided into eight and so on. If calculated at this rate, a bacterium can produce 2.2e43 offspring in 24 hours, with a total weight of 2.2e28, which is equivalent to the weight of four earths! Although the reproduction of this geometric series is often limited by the environment, food and other conditions, it is actually impossible to achieve, even so, it is enough for animals and plants to lag behind.
The premise of species definition is reproductive isolation from other species.
However, the cells and bacteria at the bottom are easy to hybridize because of their small living space and high density. The larger the species, the reproductive isolation will be formed, such as land animals and people.
2. The origin of human beings: The picture begins to show an ape drinking water, which is a very simple state.
Subtitle: "Millions of years ago, our earth was given life. What can we do? "
Up to now, the human world has become richer and richer. It is no longer just drinking water like primitive early apes. Humans can do more things. Different people, different lives and jobs.
3. Interpersonal relationships
The heroine Lucy (hereinafter referred to as Lucy) is talking to a man who has known him for a long time, and the man wants Lucy to deliver the goods for him. Lucy remembered the day when she met this man and played with him, and felt a little indebted to him.
4. repay kindness? Good people?
The man said that he went to the museum: "There is a woman named Lucy." .
The ape in the museum.
This man wants to tell Lucy to be a good person and help others. Everyone will remember her and her name and write it into history.
But Lucy's answer is: "Do you think we are good people?"
The man replied "yes" and then added "no"
Lucy means: I won't owe you a favor, repay you and help you because you have given me benefits before.
5, temptation and trap
The man continued to persuade Lucy and said, "Send his suitcase with your beautiful smile!" " "
Switch to mouse and mousetrap (with food) Food is tempting, but there are also pitfalls and costs.
6, others' coercive means
Lucy still refused, but the man simply gave Lucy $500 and handcuffed her, and her fate passively unfolded.
Step 7 pursue interests
Some movies often switch to animals. The law of the jungle in the animal kingdom and the law of the jungle switch to humans, which is also so competitive, but it doesn't look as barbaric as animals.
Panthers hunt their prey sheep.
And the heroine is like a hunted prey at this time.
Photo: The leopard successfully killed the sheep.
The man was killed and Lucy was caught. Consistent with animal pictures.
8. Fear stage
Because of her weakness, Lucy became a prey, and she was very afraid.
Fear comes from human beings and from life. Besides humans, other animals also have fears.
The source of fear is unknown. Not knowing what will happen next leads to fear.
9. Intelligent species: brain utilization rate
The higher the brain utilization rate, the smarter and wiser the species are. Therefore, human beings stand at the top of the earth's food chain.
Humans began to know how to use tools and make fires from primitive people, and began the development of civilization.
The brain utilization rate of ordinary animals is below 5%.
The utilization rate of the human brain is about 10% (the reason is probably 10%, and there is no higher improvement because human beings rely too much on tools. )
The only special case, dolphins whose brain utilization rate exceeds that of humans, has a brain utilization rate of 20%.
Although the brain utilization rate of dolphins is higher than that of humans, they have not developed civilization like humans. The main reason is that they don't have flexible limbs, fingers and feet like humans. Unable to create tool.
"We can draw the conclusion that human beings are obsessed with having the status quo ..."
Therefore, human development is also relatively slow.
10, saving time
The development of human civilization is to invent and use more tools to help people do things and save time.
1 1, independent development
"If its habitat is in an unfavorable environment, the cell will choose to be spontaneous, that is, self-sufficient ..." (self-care)
However, if the habitat is in a favorable environment, this is the choice of reproduction: breeding the next generation.
"When they die, the important data of these cells will be left behind over time through genetic cells, knowledge and professional skills." (Part of knowledge: survival instinct, the basic survival instinct inherited, is related to finding food, that is, the ability to find food. )。
For example:
Many animals are born with certain abilities, for example, spiders can weave webs without learning; Mosquitoes suck blood without learning or skill; Butterflies fly out of cocoon; Small fish can swim when they hatch; Little turtles crawl when they hatch from eggs. They know the direction to the sea. Mammalian cubs are born to suck milk; Lambs will stand quickly after birth, run a few days later, and so on.
And humans:
There are some things that people are born with, such as sucking milk, which is also a skill. Wood can't do this. You also need the brain to dominate the behavior, or many behavioral habits, such as liking to smell things, which is a habit that many people have and no one teaches.
In addition to physical characteristics, genetic genes also inherit some knowledge and behavior, but only in a small proportion.
12, change
Movie theme: What happens when the brain develops more than 10% or even 100%?
The human brain has more than 200 billion brain cells, which can store10 billion pieces of information. The mind travels at a speed of over 300 miles per hour, and has a staggered loop of over 100 megabytes, generating an average of 4,000 thoughts every 24 hours. It is the most accurate and sensitive organ in the world. The structure of human brain is divided into brain, cerebellum and brain stem. The brain consists of cerebral cortex (neocortex), limbic lobe (old cortex), brain stem and brain bundle. The cerebral cortex can be divided into frontal lobe, temporal lobe and occipital lobe.
In addition, the brain is divided into left and right halves. The right hemisphere is the "right brain" and the left hemisphere is the "left brain". The left and right brains divide all the structures of the brain equally. The left brain and the right brain have the same shape, but their functions are quite different. Left brain management language, that is, processing information with language, transforming the information that enters the brain into language to convey, is quite time-consuming; The left brain is the brain of rational analysis and judgment, which mainly controls knowledge, judgment, thinking and reasoning, and is closely related to conscious consciousness.
If the right brain of emotional intelligence, association, unknowns and feelings has a large number of memories, the right brain will automatically process these information and derive creative information. In other words, the right brain has autonomy, can exert its own imagination, thinking and visual creativity, and has the excellent function of storyteller. If it is the left brain, there is a limit to how hard you rack your brains. But as long as the memory and thinking ability of the right brain are combined, it can be connected with pure thinking and image thinking of the pre-language without language, and the original idea will be magically triggered.
For details, please refer to Baidu Encyclopedia: brain cells, left brain and right brain.
13, connection
"1 100 million people only have 15% neurons working. Humans in the galaxy are more connected. We hope to have a huge data network, but we haven't reached it yet. "
This passage paves the way for Lucy, the protagonist, to see the invisible lines connecting the sky on the human body after developing her brain. )
This statement, when you think of the cosmic database, you can imagine the universe as a super quantum computer, which connects everything and all the generated data will be uploaded to this cosmic database.
"What's the next step? It may be to control others. " (To this end, we should have a utilization rate of at least 40%. )
The idea of the film is that the higher the degree of brain development, the wider the control range. In addition to controlling yourself, you can also see the information of other humans and species, and control other species and humans.
14, shallow fear, farewell to family.
At this time, Lucy still has fear (just not as strong as before), that is, fear of death. I don't know what will happen next and whether she will die.
Fear is an instinctive reaction of creatures, born with it.
Lucy called her mother and told her how she felt now, as if she were saying her last words.
15, on brain utilization rate and brain utilization rate
In a conversation, Lucy said, "My current brain utilization rate is 100%". This is not to say that the brain utilization rate has reached 100%, but 100% of the existing brain utilization rate.
Brain utilization rate: it can be described by CPU processor on computer, percentage utilization rate.
Brain utilization rate: the range of brain use and the undeveloped part. It can be described by the core quality of CPU, such as single-core CPU, dual-core CPU, 4-core CPU and 8-core CPU. The more multi-core CPUs, the wider the scope of use.
Reasoning with 5% as the core number, 5% brain utilization rate is single core, 10% is dual core, and 20% is quad core.
40% are 8 cores, 80% are 16 cores, and 100% are 20 cores.
16, the essence and purpose of life
"It originated from the fact that the first cell was split in two, and the purpose of life was to have lofty goals through learning."
"If you ask me how I did it, I want to say that I have this knowledge. Because all basic cells travel in time (including people). "
17, no rule exclusion
Society excludes people who have no rules and don't abide by laws and ethics (as can be seen from the news paragraphs, no matter what the reason or motivation, as long as they make mistakes, they will be scolded or even chased)
18, Charles de Gaulle Airport
"Our lineage began in Charles de Gaulle, Paris."
There are two understandings about this passage:
Lucy's location is Paris airport (it was named after Charles de Gaulle, the first French president). )
(2) Charles DE gaulle's personal words before two sentences:
1, great men are great because they are determined to be great men!
2. Not too far from the moon; The longest distance we have to walk is still between us.
These two famous sayings can be well explained: "Our lineage began in Paris, Charles de Gaulle".
Lucy is developing towards greatness.
Lucy is getting farther and farther away from ordinary people, which is beyond the ability of ordinary people.
The distance between people is not material, (as long as you have money, everyone can get nothing, and this will be lost one day) but the use of knowledge, which leads to different abilities. 19, unit of measurement, social system
"All our established social systems are at the bottom 1+ 1=2"
"But 1+ 1 is not 2. Infinite and unsigned ":everything is an energy signal, and the signal can be edited and reorganized into different substances." "
"It compiles distance to reduce the scale of human beings, understands the scale of human beings and helps us forget that the world is unfathomable."
"If human beings are not units of measurement, the world is not bound by mathematical laws ... how can we rule all this?"
Lucy replied, "the car accelerates infinitely, and then the car disappears." What if they prove to exist? " The reason is that time, his own existence, is the ultimate measure. His attribute, the entity in which he exists. Without time, we don't exist. "(infinite acceleration, superluminal, and finally through time and space? )
"Time is unified"
Time is the yardstick of human civilization.
You can imagine human civilization as a movie. This movie has time, so you can fast-forward and fast-backward to see everything.
20, ignorance
"Chaos is a kind of ignorance, not knowledge": it is equivalent to illiteracy and legal illiteracy.
Some people abuse knowledge, not because they have more knowledge, but because they don't know how to use it reasonably. Some people are illiterate and ignorant of the law.
2 1, the eye of god
During Lucy's absorption of all CPH4, the image shows that CPH4 rushes into a triangle in the body. The area was closed, and CPH4 broke in. (Personal understanding is the forbidden area of the brain, the sacred area)
22. Dark matter world
In cosmology, dark matter refers to those substances that do not emit electromagnetic radiation themselves, and humans cannot directly observe them through any existing observation tools. They can only know that there are a lot of dark matter in the universe through the action of gravity.
The total mass of all observable stars, planets and galaxies in the universe is less than 4% of the mass of the whole universe. 96% of the universe is made up of some mysterious substances that scientists can't see, detect or even imagine.
Universe: ordinary matter 4%, dark matter 23%, and dark energy 73%.
Dark matter and dark energy are considered to be the most challenging topics in the study of the universe. They represent more than 90% of the matter content in the universe, and the matter we can see accounts for less than 10% (about 5%) of the total mass of the universe. Dark matter cannot be directly observed, but it can interfere with the light waves or gravity emitted by stars and can clearly feel its existence.
1932, when dark matter was first proposed, it was only a product of theory, but we know that dark matter has become an important part of the universe. The total mass of dark matter is 6.3 times that of ordinary matter, accounting for 1/4 of the cosmic energy density. More importantly, dark matter dominates the formation of the cosmic structure. The nature of dark matter remains a mystery.
It seems that fear is the bottleneck of mankind.
