Notes on community evolution

Monogamy requires human beings to have the ability to adjust their behavior and coordinate with their partners, which requires extremely high cognitive ability.

Women have won the control of cerebral cortex and developed better social skills; Men, on the other hand, won the control of the limbic system and gained an advantage in the struggle.

Eyes are actually part of the brain, and women are more sensitive to color.

Research shows that there is a significant correlation between population size and the size of cerebral neocortex. The scale of social network owned by everyone is about 150 people, which is called "Dunbar number".

The focus of the community is not only on the number of relationships, but also on the "quality" of some important relationships.

The closest circle generally consists of 3 ~ 5 people. These people are basically good friends that a person will turn to when he is in trouble.

Everyone has relatives, and relatives are connected with each other through complex biological networks.

It is best to travel long distances with relatives.

The traditional custom of naming other people's children has formed a connection between the namers and the children. They share weal and woe with the children and benefit them for life.

Touch is the most sensitive and intimate feeling. Touching is almost the first thing we do in intimate relationships. Touch is controlled by the right brain, which is the emotional center.

Smiling, especially in public, can establish a sense of connection very effectively.

Singing and dancing are usually important ways to generate a sense of belonging and collectivity, which is very basic and important in small human communities all over the world.

The main purpose of women's conversation is to maintain their social circle and establish and manage a complex relationship network in a changing world. Men's conversations are more like bragging. They always talk about themselves or what they are very good at.

The evolution of language allows us to integrate a large number of social relations. Talking allows us to exchange information about people who are not present.

We are keen on telling stories, many of which are related to our own life experiences. These stories let us know about society and give us a sense of belonging.

Intelligence, health and mortality are interrelated, but their relationship is not clear.

We need to learn to accept risks and be less willful and harsh when accidents happen. Life is full of risks. If you always want smooth sailing and pursue perfection when you encounter setbacks, you can't be grateful.

Education is not only the technical training of profound knowledge, but also the training of how to think and evaluate, how to provide evidence for supporting and opposing a certain position, and how to think critically about a problem without prejudice and influence.

Human culture is the greatest achievement in evolution. Our cultural ability depends to some extent on our own unique ability, that is, the ability to self-examine and reflect on our own feelings and ideas, especially the ability to feel the feelings and beliefs of others.

We know how to manipulate others and can read the thoughts behind their actions. This mental computing ability is a huge gap between us and other species in the animal kingdom.

Our brains lack the ability to process continuous knowledge, especially when these continuum involves the interaction of several variables with different dimensions. Humans like simple dichotomy, because such a thinking framework can prevent us from thinking too much.

Evolutionary psychologists sometimes describe us as "stone thinkers in the universe in the space age". To some extent, our thinking is the product of our brain, but the evolution of our brain is not rapid. Our way of thinking and life experience must reflect the early adaptation of human beings to the environment. This leads to a problem: many of our behaviors are incompatible with our present environment.

Research shows that people's impression of the height of successful people is often higher than their actual height.

Jury system is very necessary in real life, because diversity and complexity will bring a balanced view.

In traditional society, men look for young and prolific women; Women value men with status and wealth more.

As the importance of wealth to women gradually declines, other parenting environments have a greater impact on women's successful parenting. Therefore, more and more single women require their partners to be "caring and willing to share".

Kissing may be a test of the genotype composition of potential spouses.

A series of studies show that people are more willing to pair with people whose major histocompatibility complex genes are complementary.

The next time you kiss your partner deeply, you may stop to remind yourself that you have chosen the right partner with a good complementary immune response and successful urine protein ... For this idea, maybe you should turn off your consciousness and let the subconscious play its role and let nature take its course. Evolution didn't take millions of years to perfect the mate selection mechanism, so don't think too much.

Adventurers have an advantage in reproduction, and such people will make greater contributions to the next generation.

In mammals, there are relatively few single preparations. Only about 5% of mammals are single formula.

Childlessness is the most dangerous factor leading to divorce.

Human beings are highly alert to extramarital affairs.

Genghis Khan gene: From the perspective of sex selection, men with Genghis Khan haplotype gene have outstanding advantages in the process of reproduction.

Large-scale migration is likely to lead to the extinction and exchange of blood among those unfortunate groups in the tide of migration.

Slavery has both an ancient history and a very modern history.

Humans have a very long history, which can be traced back to the separation of apes 7 million years ago.

When the apes differentiated, several different species appeared, which were widely distributed.

The murals and artworks of ancient people tell us that they have discovered beauty in the long history that runs through tens of thousands of years. Within art, the foundation of modern human culture is buried, from literature to religion and even science.

According to the theory of intelligent design, nature is so complicated that it can only be produced through some invisible intelligent designs. This view is wrong, because most fans of intelligent design theory don't understand natural history.

Knowledge is power, and suppressing knowledge is absolutely dangerous, and such a danger is unbearable for human beings.

The reason why creationism seems credible is that fossil evidence is incomplete. Nowadays, the great progress in molecular genetics has solved the problem of missing fossils.

When we found that many animals actually use tools, our definition of human beings immediately changed from tool users to tool makers.

Human culture is deeply rooted in language, and we use language to describe, teach and recite.

Our religious rituals, literature and even advanced culture related to science all depend on our ability to go out of ourselves and see the world independently.

Our cultural heritage is being swallowed up and destroyed by the harsh scientific machine.

The core difference between humans and other animals is that we can step back from the experience world and think about what the future will be like.

The method of learning by rote plays a vital role in our intellectual development.

Our intuition drives us to decide how we and others should act. Our morality is the product of thoughts and feelings, and we will evaluate the advantages and disadvantages of alternative behaviors.

If we want to persist in practicing a certain moral behavior, we must prove it is correct with stronger power.

We believe that all people should be given equal rights, mainly because human beings have the same cognitive ability from emotion to language.

People will obey the collective will, especially religious beliefs.

Human beings hope that the surreal world and daily human nature can be perfectly combined.

Evolution is a miracle, and Darwin's genius explanation of the evolution process supports the main viewpoint of evolution.

Only a few modern people have a special mutation-lactase, which can digest the main sugar lactose in milk.

In all races, women and babies are usually lighter than adult men, including Africans.

The problem with humans is that our brains are too big. Based on the law found in other mammals, the brain capacity of human beings should be as long as 2 1 month, but it is actually only 9 months.

Unlike other primates, human babies are far from mature at birth-one result is that mothers spend more energy on their children's upbringing, which is very rare in other mammals.

Everything is just a historical accident, and there is no "natural" way for gender.

Humans have always been confused by emotional shortsightedness. In a world where technology can make desires come true, we often need very strong self-control to resist the temptation of material desires.

Establishing a smaller, more closed and exclusive community can make people without natural immunity less infected with diseases, which is an evolutionary strategy.

The imbalance of gender ratio will cause serious social problems, and the government must pay attention to it. To improve this problem, it will take several generations of efforts, or even longer.

The change of species is realized by the gradual decline of some genetic lineages, so that the genetic composition of species can subtly and steadily supplement those more successful lineages.

In evolutionary history, there have been five mass extinctions. The last extinction occurred 65 million years ago, which caused dinosaurs to disappear from the earth. At present, there are about 1 1000 species of animals and plants in the world, and as many as half of them will be extinct in the next century.

The extinction of language is like the disappearance of animals and plants. We are witnessing the rapid decline of language. Language has the same biogeographic and evolutionary characteristics as biological species. The extinction of small languages will cause irreparable losses to mankind.
