Where did humans come from and where did humans come from?

1.It's a great question, people are all evolved. Human beings did not simply evolve from apes, but a kind of other creatures, and the theory of evolution simply explained the later evolution of organisms, but did not explain the specific origin of biological species, which made Darwin's theory of biological evolution also began to be questioned to varying degrees.

According to scientists' research, the earliest life discovered by human beings so far comes from the history of 4.5 billion years ago, which is the same age as our sun, so some scientists further proposed that human life came from extraterrestrial meteorites, and they believe that 4.5 billion years ago, meteorites from extraterrestrial fell directly into human ice, causing high temperatures because they did not collide with the ground. 2.One theory, about the ** of human beings, many people or some absurd schools of thought believe that human beings are fabricated by Nuwa Niangniang with mud, and always think that there is a kind of dirt on people's bodies that will never fall off is the best proof, but it is obvious that Nuwa created people only exists in fictional Xianxia TV series.

At the same time, there is also a saying in the Bible that the ancestors of human beings were Adam and Eve, and they were borne. Another theory, Darwin's theory of biological evolution said that human beings are due to the evolution of apes, but in recent years, many biologists and anatomists have begun to doubt Darwin's theory of biological evolution, if the theory of evolution is overturned, human beings are not simply evolved from apes, but a kind of other organisms, the theory of evolution simply explains the later evolution of organisms, but does not explain the specific origin of biological species, which makes Darwin's theory of biological evolution also began to be questioned to varying degrees. According to scientists' research, the earliest life found by human beings so far comes from the history of 4.5 billion years ago, which is the same age as our sun, so some scientists further proposed that human life comes from extraterrestrial meteorites, and they believe that 4.5 billion years ago, meteorites from extraterrestrial fell directly into human ice, because they did not collide with the ground and caused high temperatures, so its chemical elements did not change

Humans evolved from "ancient apes" to humans.

Humans are classified from the animal kingdom, and taxonomically homosapiens belong to the subphylum Vertebrates, Mammalia, Primates, Apes, and Hominidae.

About 4.5 million years ago, humans and apes began to diverge, giving rise to Australopithecus ramanacus, which later evolved from Australopithecus australopithecus 2 million years ago, and then further developed into modern humans. Regarding the process of human development, it is generally divided into four stages:

1. Early ape-man stage. It lived between 3 million and 1.5 million years ago, and already possessed the basic characteristics of humans, such as being able to walk upright and make simple gravel tools. 2. Late ape-man stage.

About 2 million to 300,000 years ago, the body resembled a man, the brain was larger, and it could make more advanced paleolithic tools, and began to use fire, such as the Beijing ape man in Zhoukoudian, Beijing, China.

3. Early Homo sapiens (hominid) stage. Between 100,000 and 200,000 to 50,000 years ago, it gradually broke away from the characteristics of apes and was very close to modern humans, such as Neanderthals in Germany. 4. Late Homo sapiens (newcomer) stage.

About 4-50,000 years ago, the evolution of human beings at this time showed a significant acceleration, and the morphology was very similar to that of modern humans, and culturally, there were already the art of carving and painting, and ornaments appeared. For example, in 1933, the cave man on the top of Zhoukoudian Keel Mountain was discovered. At this time, primitive religions had already arisen and had entered a matriarchal society.

In the late Homo sapiens stage, modern humans began to differentiate and form, and spread throughout the world.

One is the theory of natural evolution. This statement is that there is no life on the earth, not even organic matter, only inorganic small molecules. Under the action of cosmic events and the earth's lightning and thunder, the earth's matter evolved from inorganic small molecules to organic macromolecules, and then gradually evolved into proteins, generated the first cells, and finally formed life.

This whole process has been brewing for hundreds of millions of years, full of accidental and inevitable collisions, therefore, life is the darling of luck.

There is also a saying that it is said by visitors from outside the sky. This theory holds that life on Earth comes from the universe, at least organic molecules from the universe, through the impact of meteorite comets, to the Earth, and then gradually evolved into today's lush nature in the Earth's natural environment. In this sense, the earliest ancestors of human beings were organic matter or even cells or bacteria from outside the sky, and these cells or bacteria can be understood as being brought from a planet with life, so it can also be said that human beings are born and evolved from alien seeds.

In addition, there is no evidence that human beings came to the earth to reproduce or were created by aliens, and in all the comprehensive research of archaeology, biology, and genetics, human beings can only be born and raised on the earth.
