We humans are conceived by the mother, the father's sperm and the mother's egg combine to form a fertilized egg, which is born in our mother's womb for ten months after childbirth.
Mothers are great, because the process of childbirth is very painful, and many people try to experience the pain of mothers in childbirth by simulating labor pains.
It is difficult to imagine how a mother endures the pain of childbirth at the ninth or tenth level when she gives birth to us.
Some people may wonder, since it was a woman who gave birth to a man, then who gave birth to a woman, and where did the first woman come from before there were no human beings?
1. How did humans come about?
At present, the number of people on the earth is still very large, according to statistics, the number of people in the world is close to 8 billion.
China and India are the most populous countries in the world, with a population of 1.4 billion people alone. It took nearly two centuries to usher in a new round of population growth. From the twentieth century to the twenty-first century, the global population has increased by nearly 5 billion people in just one century.
The growth of population has a certain relationship with the development of productive forces and economic progress, and after the first and second industrial revolutions, the production efficiency of human beings has been greatly improved, and we have entered a more convenient and fast era.
As the population grows, there may be problems with the uneven distribution of resources.
The evolution and evolution of the earth is still relatively long, up to millions of years. 10,000 years ago, the population of the earth was relatively small, only 5 million people.
After 5,000 years of development, only 5 million people have increased. Looking at the history of human origin and development, all human beings on the earth have a common ancestor, that is, Homo sapiens.
On the basis of primitive human beings, through evolution and evolution, human development and evolution are related to the surrounding environment, thus forming human beings of different colors and races.
Now the human beings on the earth are divided into white races, yellow races, black races, and so on. We Chinese are yellow and live in the eastern part of Asia.
Humans have a common paternal ancestor, and males have a Y chromosome, which is passed from male to the next generation of males, and so on.
And both chromosomes in a woman's body are X, and the X chromosome can be passed on to both the next generation of males and the next generation of females. In the process of synthesizing DNA in the human body, mitochondrial cells provided by the maternal line are very important synthetic resources.
Who was the earliest matriarchal line? There is a legend on the mainland that Nuwa created a man, and it was Nuwa who made small clay figures according to her own imagination, and these clay figures transformed into human forms and became the earliest human beings.
After all, myths are myths, representing the good wishes of human beings, and there is no strong scientific basis.
There is also the story of Adam and Eve in Western mythology, and in the eyes of Westerners, Adam and Eve were the first humans in the Garden of Eden.
The two bonded to give birth to the next generation of human beings, and so on, and so on, and so on, and so on, and so on, and so So, who was the first human woman?
Scientists have found traces of human evolution in the fossils of the earliest fish, which were hermaphroditic and appeared in the ocean about 380 million years ago.
These earliest fish mated and sexually reproduced, giving rise to more new fish. In this way, it multiplied and reciprocated from generation to generation.
Are the reproductive characteristics of human beings the same as those of fish, and did hermaphroditic humans exist at the earliest? Scientists are still further exploring and thinking about this question.
Combined with the breeding experience of fish, after the research and experimental investigation of scientists, the earliest traces of human females were found in the African region.
According to experimental research, the earliest common female ancestor of all mankind was an African human 150,000 years ago.
Westerners refer to her as "Mitochondrial Eve" in honor of the earliest human female in Western mythology. Scientists investigated the environment and background of that era, and found that there may have been other human females at that time.
However, at that stage, the climate change was relatively abnormal, which made it difficult for the earliest primitive humans to adapt to the environment at that time, and many of the earliest humans could not survive in such a bad environment.
So very few humans survived at that time, and "Mitochondrial Eve" was one of the few women who survived that era.
The mitochondrial DNA in the body of "Mitochondrial Eve" will be inherited and multiplied from generation to generation with her birth of a new life.
According to the principles of biological fertility and genetics, women need to have the participation of men in giving birth to the next generation. And was the male who was bound to the "mitochondrial Eve" at that time the earliest male ancestor?
Scientists have found that the "mitochondrial Eve" may not exist at the same time as the man, and even the "mitochondrial Eve" is many years earlier than the man who contains the Y chromosome.
Therefore, when the "mitochondrial Eve" conceives the next generation of life, most of the women contain the X chromosome, and most of them are female offspring.
2. The history of human evolution and evolution
After the appearance of the earliest primitive humans, human beings began to undergo new changes through continuous migration. About 80,000 years ago, hominids living in Africa began to move out of this familiar area and into Eurasia, where many Neanderthals gathered.
Neanderthals bonded with hominids in Africa, resulting in a new species of humans.
Since then, human beings have continued to travel to new areas, constantly combining with races from different regions, and in different environments, there have been new changes, and more races have appeared.
And primitive human beings are also constantly improving and self-improving, at first these human beings have just come to this world, and they feel strange to everything in the world.
And the earliest humans evolved from animals, and they walked in the same way as animals, which was a four-legged walking style.
Gradually, human beings began to adopt the way of standing and walking, and with continuous evolution and evolution, human beings gradually showed many differences from animals.
3. Humans learn to use tools
Instinctively, they need to forage for food, and generally choose to pick up food on the ground with their hands, and they have no choice about the food they eat.
And when they encounter more food and things, humans begin to make choices about everything around them. I also began to think about how to use tools to make life more convenient, and began to try to make a fire, using fire to heat food and make food taste better.
Human beings have a relatively long history of reproduction and evolution to get to where they are today. Taking China as an example, China has a long history of 5,000 years, and has gone through many stages such as primitive society, slave dynasty, feudal dynasty, Republic of China period, and new period.
The society is also gradually developing and progressing, and the ancient Chinese have exerted their ingenuity and created many interesting inventions, so that modern people can learn from and learn from them.
In the current era, with the rise of artificial intelligence, many people may be worried about whether artificial intelligence will replace human beings one day in the future and seize the original living space of human beings.
In fact, no, the biggest difference between humans and other animals and artificial intelligence is that humans have the ability to think independently, and their own behavior is controlled.
It is because of the emergence of human beings that human beings have exerted their wisdom and talents to make so many new things appear in society, and life has become so intelligent, convenient and fast.
And artificial intelligence was also born under the creation of human beings, so artificial intelligence cannot replace the human beings who created them at all.
Fourth, be grateful for your mother's dedication
Having explored the origins of the earliest women, one thing we can be sure of is that the emergence of any human life is related to women.
We all have our own mothers to give birth, and in the process of nurturing and raising us, mothers have experienced bitterness that no one else has experienced.
The process of giving birth to a child is very painful, and the mother needs to go through a thousand times more pain than ordinary people to give birth to us.
As we grew up, our mother sacrificed her personal time to grow up with us, teach us to speak, lead us into this strange world, and gradually familiarize us with everything in it and adapt to the new living environment.
We should be grateful for our mother's dedication, and when we have the ability, we must know how to repay our mother.
We must learn to cherish our own lives, and the birth of every life is not easy.
Every independent individual existence in this world has its own unique value, we must learn to appreciate ourselves, discover our strengths, create more value for this society, make ourselves more valuable, and live a more meaningful life.
We will hear social news of suicide in our daily life, this kind of behavior is disrespectful to life, but also disrespectful to the mother who gave birth to us, this kind of behavior is not advisable.
epilogue
In the East and the West, each has its own myths and legends about the origin of human beings, with the East being the legend of Nuwa creating man, and the West being the legend of Adam and Eve making a baby.
From the myths and legends of the East and the West, it can be seen that people have been tirelessly pursuing the truth of the origin of mankind. Humans are conceived by motherhood, and where the earliest women came from has always been a mystery.
After in-depth research and observation by scientists, the earliest primitive human female was found in Africa 150,000 years ago, and she inherited the mitochondrial DNA in her body from generation to generation.
Newly born humans came to more areas and combined with different races, giving rise to more new humans and more races.
