Human beings have evolved one by one or together. Please explain in detail.

There are two theories of human evolution, single origin and multiple origin, but based on evidence such as fossil data, the academic community tends to believe that human beings originated in Africa, that is, single origin. The single origin theory is that after coming out of Africa, one group followed the coast of the Indian Ocean and went east into Asia, and the other crossed the Red Sea and went north into Europe, which is a dispersal route, and there is also a theory that from Africa along the coast of the Indian Ocean eastward into Asia, and then a part of Asia branches around the northwest into Europe, which is another dispersal route, which is currently controversial about these two dispersal routes, but recent genomic data support the second dispersal route. However, the Chinese civilization is the only existing four ancient civilizations in the world, with such a splendid culture, Chinese scholars certainly want to prove that human beings have multiple origins and evolved independently, but at present, China lacks fossil evidence of an important era.

Therefore, in terms of the current state of scientific development, it is believed that human beings originated in Africa and then "traveled" to other regions. But the truth is always known step by step, and the understanding of things is always based on the current understanding, so with the development of science or the emergence of some evidence, perhaps our understanding of the origin of human beings will be different. I probably know this, of course, it's not very professional, I can only say a rough idea, I hope it will help you.

Evolution is based on populations, not individuals, so it is not one by one, and it doesn't matter if an individual evolves.

Evolution is based on populations, and it cannot be one by one.

It is believed that human beings did not appear by chance, and why do you say that, we all know that there were two mass extinctions before the emergence of human beings, one was the age of cold-blooded animals, that is, the age of dinosaurs. After the sudden extinction of the dinosaurs, the age of giant mammals came, and then suddenly they all disappeared overnight, and they all became extinct. However, after the defeat of wisdom, the emergence of small animals and humans in our modern era.

According to the theory of evolution, animals evolved from single-celled organisms, that is, evolution from lower to higher levels. Then, after the first two mass extinctions, the earth should have reshuffled from a single cell to a modern animal, including humans. But the fact is that the animals that survived together in the earliest age of dinosaurs, such as snakes, turtles, crocodiles, spiders, flies, mosquitoes, dragonflies, rats, fish、、、 and so on, did not go extinct with the dinosaurs and later giant mammals, and have flourished to this day, but some germlines have perished.

Moreover, after hundreds of millions of years, the appearance and body structure have hardly changed. What is the theory of evolution??? The fact in front of us is that the huge dinosaurs seem to suddenly appear in the global village overnight, and suddenly all disappear and become extinct overnight.

After the extinction of the dinosaurs, so many animals that did not become extinct (turtles, snakes, crocodiles, lizards, spiders, frogs, rats, flies, mosquitoes, centipedes, various fish, etc.) were born at the same time, and new single-celled organisms survived together, and then evolved new species??? Old and new species co-emerge??? Or did modern animals and humans evolve from these surviving creatures?

So did the ancestors of man evolve from turtles, snakes, or flies? Isn't the great theory of evolution pure nonsense???

Summary. Will human beings really evolve, I think they will evolve, and only by constantly evolving can we grow, and evolution is the nature of living beings. Every organism undergoes genetic mutations in the process of evolution.

Variants that are more adapted to the environment are left on Earth after being naturally selected, and this is evolution. Are humans still evolving? Scientists said

The evidence is clear, and there is no doubt about it, but after so many years, humanity seems to have changed little, leaving many people with deep doubts: Has humanity stopped evolving? Could it be that humanity has reached the end of its rope?

Scientists said: Actually, this is just our misunderstanding. There is several evidence that humans are still in the process of evolution.

Do humans really evolve, I think they will evolve, and they can only grow if they continue to evolve.

Will human beings really evolve, I think they will evolve, and only by constantly evolving can we grow, and evolution is the nature of living beings. Every organism undergoes genetic mutations in the process of evolution. Variants that are more adapted to the environment are left on Earth after being naturally selected, and this is evolution.

Are humans still evolving? Scientists said: The evidence is obvious, there is no doubt However, after so many years, human beings seem to have never changed, which makes many people have deep doubts:

Has humanity stopped evolving? Could it be that humanity has reached the end of its rope? Scientists said

Hello teacher, the voice you have made is not very agreeable, and human beings will definitely be able to rise step by step.
