It is true that humans could not have appeared out of thin air on Earth, there must have been an origin. However, in the study of human origins, there is no such thing as the "first man", and certainly there is no such thing as "the first man and woman". The origin of human beings is a long evolutionary process that involves the differentiation and evolution of multiple species.
According to the current scientific consensus, life originated in the primordial oceans on Earth. As early as about 4 billion years ago, in the chemical environment of the Earth, a series of organic molecules formed spontaneously, which eventually led to the emergence of primitive life. Life evolves and diversifies over time. In the process of biological evolution, a series of important events have occurred, such as the emergence of eukaryotes, the development of multicellular organisms, and the evolution of sexual reproduction.
After the extinction of the dinosaurs about 65 million years ago, mammals began to develop rapidly. Among them, primates are gradually emerging, they have relatively large brains and flexible hands and feet. These traits laid the foundation for the evolution of humanity.
According to current scientific research, scientists have given two mainstream views on the origin of humans: most scientists believe that modern humans originated in Africa;Other scientists have proposed the theory of multiple origins, suggesting that modern humans may have evolved independently in different regions. However, I believe that in the future, with the continuous progress of science and technology, we may be able to find more evidence about the origin of human beings and further reveal this mystery.
Although we are not yet able to determine the exact time and place of the birth of humans, some possible scenarios can be speculated based on the available fossil record and genetic evidence.
The evolutionary process of human beings is a long and complex process that has taken millions of years.
According to scientists, the ancestors of humans were primates, who lived in the forests of Africa. About millions of years ago, these great apes began to diverge into different species, some of them began to walk upright, and some of them eventually evolved into modern humans. This is considered an important milestone in human evolution. However, there are also studies that suggest that the upright walking apes may have appeared 12 million years ago, millions of years earlier than is generally believed. This ape lives in southern Germany.
Over time, these upright walking apes evolved larger brains, more sophisticated tool use, and more developed language skills. About 2 million years ago, early humans appeared, such as Homo Homo and Homo erectus.
Since then, humans have continued to evolve, and different Homo sapiens such as Neanderthals have emerged, but most of them eventually became extinct. In a brutal competition, one of them, Homo sapiens, won about 200,000 years ago and gradually spread across the globe on the African continent to develop into modern humans.
In terms of biological classification, modern humans belong to the family Homo in the order of primates, and the common ancestor of the hominidae is an ape that lives in Africa. Hominids are a big concept that includes modern humans as well as extinct human relatives such as Neanderthals and Homo erectus. In addition to humans, hominidae also include some apes that continue to this day, such as chimpanzees, gorillas, etc. These animals share similar body structures and behavioral characteristics to humans, such as walking upright, using tools, having complex social behaviors, etc. They are cousins of modern humans and extinct humans.
The evolution of human beings is a gradual process, a process of constant adaptation to the environment, and a process of continuous development and progress. In this process, there is a need to diverge and merge multiple populations, with a large number of branches and intermediate species disappearing and extinction. In addition, human evolution is a complex process that is influenced by a variety of factors, such as environmental changes, genetic mutations, natural selection, etc.
Therefore, even if we can be sure that an individual is the ancestor of modern humans, it is impossible to determine whether the individual was the "first person", because his genes may have been transmitted in the population for a long time.
In conclusion, in the study of human origins, the concept of "first man" does not exist, because the origin of human beings is a group phenomenon, not an individual phenomenon. If we have to identify a "first", it can only be said that the first group of hominids was born millions of years ago, and gradually evolved from more ancient primates.
