There is no one on earth, how did the first "person" appear? Is there a man or a woman first?

The origin of mankind has always been the answer we are all pursuing. In order to find the secret of the emergence of the first man, scientists have made a lot of efforts for this. According to the results of world biological research, about 6 million years ago, there was no Humanity also unveiled the first human appearance on earth.

Darwin The theory of evolution, Darwin once traveled around the world and wrote a copy of the law of survival, which is the point of view of biological evolution he mentioned in the 19th century. In the evolutionary process of every living thing, the ancestor of mankind, the ape, was mentioned in the metamorphosis under the "survival of the fittest, natural selection of things", and now human beings emerged.

He believes that the original appearance of living things is different from the appearance of tens of millions of years. Living things will make corresponding changes as the environment changes. After tens of thousands of years, humans will gradually change The apes evolved into what we are today.

Later, from the genes of humans and chimpanzees, scientists found that there is a high similarity, which is also one of the basis for a scientific argument.

Are apes and monkeys the ancestors of humans?

In fact, this is not the case. Humans are a general term for all species, but they can only be understood based on fossil remains. They belong to the primate anthropoid suborder Hominid; and the scientific name of humans is Homo sapiens , which is Hominid extant The only genus and species of primates.

and it is said that our common human ancestor is Australopithecus ,It was first discovered in of the African continent. With the passage of time and changes, ancient ape also evolved into different races, and after evolutionary evolution, the first'human' appeared on the earth. It can be seen that the emergence of human beings did not happen overnight, but has undergone a transformation from apes to humans.

So what is the process of transformation from ancient apes to humans?

This should be counted from 85 million years of human ancestors, primate appeared at that time, and humans evolved from primates. According to scientists, primates Between 25 million years, one has evolved into a monkey, and one has evolved into an ancient ape.

As mentioned above, the ancient apes are the ancestors of human beings. . In fact, the ancient apes did not directly evolve into humans. They also evolved into chimpanzees over time. This is also where scientists later did research on chimpanzee genes. It was found that the genetic similarity to humans was 99%, which led to the definite conclusion that our ancestors and the ancestors of chimpanzees are ancient apes, which are different from the changes that have occurred during the evolutionary process.

chimpanzee human evolution transformation?

According to scientists, about 2.5 million years ago, apes evolved into capable humans, while humans evolved to walk upright 2.8 million years ago, and then to Neanderthals 30,000 years ago, and finally evolved into humans. It’s just because the most critical metamorphosis skeleton has not been found, and there is controversy. We will talk about it later.

So since humans evolved from apes,Then there is another question, how did the apes come from? Which species of evolved ?

The origin of the apes: 13.5 billion years ago, after the Big Bang, after 300,000 years, the hn energy of matter began to form a complex structure, which is called atoms, and later formed molecules. Some molecules on the earth The combination forms a particularly large and fine structure-an organism.

With the passage of time, the organism has become more complex and finely formed cells. With nucleus, there will be life forms on the earth. With the influence of the environment, cells biological differentiation, cells There are more and more species of living things, and the difference between the sea and the land in the living space, including the cell organisms on the land, the ancient apes are also included.

As for the exact species of the ancient apes, this is like a well-known theory, whether it’s the egg or the chicken. There is no accurate conclusion in the scientific community.

briefly introduces the appearance of people, so is it the first man or woman?

While studying the origin of mankind, scientists traced human genes and discovered that there was a male Homo sapiens in Africa 250,000 years ago, and his Y chromosome exists in all males now, while females It was discovered that a woman in Africa 150,000 years ago, her X chromosome existed in women now.

Is this enough to prove that there is a man first, and then a woman? Obviously it is not completely correct. Scientists' discoveries only infer the time when the origin of mankind was discovered. From the perspective of human history, human beings were matrilineal clan at the beginning, and the female dominated social development at that time.

Over time, matrilineal society has transformed into paternal clan, which is due to the development of human technology,And the inevitability of the gradual increase in the male labor force.

According to the research of scientists, the earliest period of biological heredity and reproduction is asexual reproduction, which has changed with the evolution of organisms. According to this theory, whether men appear first or women appear first, does not exist The substantive meaning of first come, first come.

Maybe at the beginning, human beings did not distinguish between men and women, but as life continued to evolve, eventually human male genes and female genes were differentiated, and there were men and women, not necessarily.

Is the first "human" on earth really evolved from the ancient apes?

Question one:

The answer that humans appeared is actually controversial among some scholars. With the scientific research of biological evolution, more and more scientists speculate that humans may not have evolved from apes at all. Yes, the theory is to judge from the walking of apes and humans.

Some scholars believe that apes are on all fours, while humans are on both legs. Scientists have not found the most critical 2 million-year-old human skeleton, which means that it is impossible to confirm how humans changed from walking on all fours to legs. What about walking?

This key missing piece of evidence has left doubts about the origin of mankind.

Suspicious two:

In the comparison of apes and human body structures, scientists found that apes themselves are aggressive and their physique is quite good, while humans are very fragile and do not have the aggressiveness of apes at all. .

Question three:

There are thousands of creatures on the earth, and in terms of the adaptability of living beings to the earth, human beings are indeed the lowest adaptability to the earth. Under many external natural factors,It is difficult to resist many things, such as ultraviolet rays, or viruses.

For this reason, whether humans evolved from ancient apes, or whether humans are "foreigners" on earth, there is no specific answer. Maybe the origin of mankind is the evolution of Darwin, maybe Humans are like some scholars have guessed.

This is like a version of various myths. Human beings are and Nuwa are made from soil. Maybe the origin of human beings is like human endless Chile. It is a mystery that will never be discovered. .

Regardless of Darwin’s theory of evolution or the belief that there is a gap of hundreds of thousands of years in the evolutionary history of mankind, during this period, mankind seems to appear suddenly and directly, so they think that mankind is likely to be a higher-civilized creature Inferences made from manufacturing, I believe that recommendations over time may eventually give us an exact answer.

What kind of possibility do you think is the origin of mankind?
