How Human Intelligence Is Produced.

Human Intelligent 

Human beings evolve under the influence of the outside world, and they influence the outside world with their own will. Today, SPOTO will give you the common sense that is related to our lives.

Although more than 100 million years ago, dinosaurs who weighed hundreds of times more than humans dominated the Earth, they were only "low-level animals" and there was no indication that dinosaurs developed advanced intelligence. Humans continue to evolve their own tissues through genetic mutations, enabling them to more fully engage with the outside world and thereby generate stimuli, such as in terms of touch, sight, hearing, smell and so on. More importantly, the brain also has a memory function, which makes human beings know the "self" and "outside" in contact with the external environment, and clarifies the physical boundaries between the various parts of the human individual and the outside world.

Through various external stimuli, the human brain is continuously strengthened and the brain capacity is also growing. The neural network inside the brain is becoming more and more complex, and its complexity is even more complicated than the universe. A large number of complex neural networks are connected to each other through synapses, thus enabling the generation of advanced intelligence.

Origin of Life

At the beginning of life, there was no brain, not even nerves. In ancient times, the earth did not have any life until the emergence of ribonucleic acid (RNA) and protein in the ocean. From today, these substances, which are not like life, are the most primitive forms of life; after the appearance of deoxyribonucleic acid (DNA), Continue to combine with the original RNA and protein to form an initial life; then continue to evolve into a single-celled organism, such as paramecium. During this period, life has not evolved nerves, and there is no brain.

The emergence of multicellular organisms allows life to develop into cranial nerves. The subsequent arthropods develop ganglia that gather nerves. The ganglia from the spinal cord in the back. The top of the spinal cord develops into hundreds of millions of nerve cells. Brain. At this point, life evolved into spinal animals and possessed the brain. Spinal animals evolved according to fish->amphibians->reptiles->birds->mammals->humans, and the brain evolved. The evolution of life also allowed life to move from the ocean to the land sky.

Mysterious brain

It takes about 20 years for the human brain to form and perfect, and it will take shape after about 20 days of fertilization. At 3 months of pregnancy, the brain, midbrain, cerebellum, spine, etc. develop. The number of nerve cells in the brain is basically the same as that of adults at 9 months of pregnancy, and the appearance of the brain is the same as that of adults. Then start building a neural network, which will last until the age of 20 years.

Quality is not the determinant of brain intelligence, but the construction of neural networks. The brain of a baby born is only about 400 grams, and the adult is 1200-1500 grams. About 6 years old, the brain weight reaches 95% of adults, and then it develops slowly. It should be noted that the weight of the brain is not the increase of nerve cells, but the increase in weight caused by the complexity of the entire neural network.

There are about 100 billion neurons in the adult brain, which form a super complex neural network through 100 trillion synaptic connections. The number of neurons in infants has been similar to that of adults in early childhood, but there is no connection between neurons, or the connection is very weak. As the child grows, the neurons are constantly connected to form a neural network, which generates intelligence.

Smart individual volume

In our entire universe, the volume of matter ranges from a negative of 19 centimeters to a cosmic limit of 10 to 26 square meters. Although the whole world seems to be infinitely small and infinite, the size of all living bodies is in a small range.

The size of the bacterial virus is on the micron scale, the largest redwood tree is up to 100 meters, and the honey fungus in the Blue Mountain forest area of Oregon can reach 4 kilometers wide. The range of intelligent individuals is smaller throughout life.

According to computational theory, individuals with perceptual power and intelligence need trillions of "circuit" components. If we can create components that are sized by brain neurons and can connect them to work, the size of the artificial intelligence is also about the order of meters. It may be said that the meter is the most suitable size for advanced intelligence, and advanced intelligence is reflected by the macroscopic whole and has little correlation with the microscopic quantum level.

Imagine if the solar system is the brain of a living body and the nerve signals are transmitted at the speed of light, then this living body will not be able to evolve. Because the solar system has only 10,000 pieces of information from the end to the other end from the time of its formation, it cannot evolve at all. The human brain can be delivered in about 1 millisecond, so two trillions of signals can be transmitted in a lifetime, which is enough for the individual to evolve.

self-conscious

Self-awareness is the pinnacle of nature. Any life has a certain self-awareness, but some living bodies have a weak self-awareness, and humans form a strong self-consciousness due to their own physiological conditions and growth environment.

Human perception of the outside world is determined by human genes, and this ability is continuously passed down through DNA. Once these perceptions are available, human beings can distinguish between the self and the outside world, which is the basis for generating self-awareness. With the ability to sense, you can get all kinds of signals from the outside world, and humans can encapsulate various signals from the outside into one concept, such as the sky, white clouds and so on. Human beings continue to fill concepts into the brain neural network during their lifetime, in order to reach the outside world.

Cognitive system

Brain cognition is divided into two major systems: one is intuitively related and the other is reasoning and logic. With regard to the intuition part, human beings distinguish between the self and the outside world through brain consciousness, while the neural network formed by the neural cells produced by the brain can think from a third-party perspective and then know the world. With regard to the reasoning and logic, humans obtain the inference results through the reasoning and logic analysis of the existing cognition of the brain, and the intuition part can be transformed into reasoning and logic.

Advanced intelligence

Human beings continue to get external stimuli through their own perception systems, and brain neurons continue to build and strengthen connections, making humans have a strong sense of self. In addition, thanks to the memory ability of the brain, human beings have gained recognition of the outside world through their perceptual abilities, and have obtained conceptual systems, value systems, and belief systems.

With self-awareness and cognitive systems, humans are gradually moving towards advanced intelligence. With the increase of the perception of the outside world, human beings continue to understand the world and constantly evolve new concepts, and human beings have produced more and more advanced intelligence.

Original meaning

From a physical point of view, human beings are made up of a large number of atoms and molecules, and self-awareness is produced by individuals composed of these atoms and molecules. Cognitive systems, advanced intelligence, and so on are all macroscopically reflected. Any conscious individual can participate in the evolution of the universe and have an impact on the physical world.
