Where do people come from? This ancient proposition has been studied by several generations of biologists, and it has basically been determined where the ancestors of human beings came from and where they were born. But now there is a new question: "Who is the first person?"
Where do people come from?
If you want to trace the origin of the human species, you must first understand the evolution process from matter to life in nature.
In the Miller Yuri experiment that simulates the conditions of the ancient earth, people discovered amino acids, the basic substances that constitute all life. This amino acid is only born near volcanoes or oceans struck by lightning. Therefore, the origin of the immediate species is divided into "lightning origin" and "ocean origin".
Subsequently, different basic forms of life evolved in different periods, such as from aquatic to amphibious, and from amphibious to terrestrial life. But this is not a single evolutionary path. For example, both humans and monkeys belong to mammals, but we have no blood relationship with monkeys. And the "people" of the past are not human beings as they are now.
has evolved a large number of "humans" after repeated mutations and accumulation of genetic material from generation to generation, and only one of them is the current human being.
According to the current definition of "human", the closest thing to us is the Alpha Australopithecus and Homo sapiens unearthed in Ethiopia, Africa. The skull cross-sections of these two species are the most similar to those of humans today. Similar, scientists also believe that they are the dividing point between the two races of ancient man and ape man.
After Homo sapiens and Australopithecus , Homo erectus, Homo sapiens, Neanderthal and other Homo species appeared, and many branches of these races have evolved. Zhoukoudian The fossils of the Beijing people come from Homo erectus who walked out of Africa 1.8 million years ago. These races are distributed almost all over the world, but most races have not been able to continue to evolve.Today, the world’s mainstream academic view believes that humans originated from the Homo sapiens in Africa. They rushed out of Africa 200,000 years ago, went to the world, and then survived tenaciously on their own, and evolved into what they are today.
Who is the first person?
In history, the debate about who is the "first person" in the world has never stopped.
In Eastern and Western mythology, there is always an inexplicable worship of "first": the first thunder, the first ray of sunlight, the first flame, etc., they all played an important role in the process of creating the world by the gods. effect.
And the first human, the same.
In the Western world, God created the first man " Adam " and the first woman "Eve". Their behavior of stealing the "fruit of wisdom" led to the fate of later humans suffering in the world.
The first "person" in Chinese mythology was to split the world with an axe, creating the Pangu of the world. He supported the heaven and the earth with his body until the heaven and the earth were completely fixed. After death, he used his body to create the sun, the moon, and the stars, storms, thunder and lightning. It is said that Nuwa was based on Pangu when creating humans.
But mythological stories are fictitious after all, otherwise countless ancients would not have to discuss the question of "who is the first person?"
But with the development of biology, the theory of evolution appeared. Everyone already knows one thing, that is: modern humans did not originate from a certain individual or a certain couple in a certain ancient people's ethnic group.
After all, from a scientific point of view, this statement itself is extremely unscientific.
The laws of nature will never allow a species or a pair of male and female species to successfully reproduce a huge population by their own efforts.Even the frogs and flies that lay the most eggs in nature can't do it, let alone humans.
Although purely theoretical, a couple may have many children. But it's just that. Regardless of the ethical issues that may arise between the offspring of the couple, the genetic defect caused by "close relative marriage" alone is fatal. This fatal defect will cause the offspring of the couple to quickly become extinct and multiply billions. Population is absolutely impossible.
Therefore, there is no "first person" on the earth. We are all human beings from the ancient African Homo sapiens. It took 200,000 years to gradually become human beings.
