It is already a most critical issue from the beginning of nature's project, in some ways, we humans evolve very quickly, although evolution itself does not expect, but environmental selection always chooses the obvious advantages of the environment at that time, which is very short-sighted, although the process of change is always very long, we and other species, in the process of evolution, there is no difference. However, it is clear that over the past 10,000 years, non-genetic changes similar to the changes in the ideological and social formations of our communities have been particularly rapid.
About 60 million years ago, due to the climate change at that time, larger animals such as dinosaurs became extinct, and mammals were smaller. However, the extinction of some species leaves more room for others to survive, so mammals develop and grow, and here I ignore the more distant past and only talk about primates among mammals, with the aim of discussing our history of separation from other peers, including the reasons why we acquired technology later.
Why do we have long fingers, intelligence is not an all-or-nothing phenomenon, humans are smarter than chimpanzees, chimpanzees are smarter than dogs, dogs are smarter than mice, rats are smarter than starfish, humans are intellectually extreme compared to other species. But we're not the only extreme species, whales are extreme in size, hummingbirds are extreme in flapping their wings, viruses are extreme to a very small extent.
Giraffes are extreme in their long necks, our world differs in size, shape and variety, and naturally, different creatures are at extremes with different characteristics, and for humans this extreme happens to be intelligence. So for the previous question, we need to know that humans are not the only creatures that have become smarter, we just happen to be the most intelligent species. We're not particularly big in size, we're not very fast, but wisdom is just what makes us special.
As for the evolution of human beings into the most dominant species on the earth, which evolutionary link is the most critical, it will be explained here today.
-
Human evolution stems from four stages, namely ape-man, hominid, sapiens, and modern human. In the evolution from primates to the most dominant species on earth, from the second stage, the evolutionary link of primitive humans is the most critical, belonging to the initial transition process from animals to humans.
-
Human beings have evolved into the best species on earth, and one of the most important links in the evolution is that humans use fire sources to start cooking cooked food. This plays a very crucial role in the evolution of human beings, providing sufficient nutrients for human evolution.
-
Biological and evolutionary perspectives, it is very correct that humans sweat and are an important reason for how humans evolved to become the topmost predators of the planet.
-
Can humans evolve to become the rulers of the earth without effective sleep at night?
-
Why are humans intelligent? It's simple. As long as there is a soul, as long as there is knowledge given by fate and fate, there must be human wisdom to explain life.
Without a soul, man is just a corpse, without life and without wisdom. There are billions of species on Earth, and we humans coexist in this world, how long have we been together? Are they all from **?
Before us? Or is it after us? Who created their shape?
Why do they eat,, sleep?
<> why do they need air and water too? Why are they so different from us? And some organs and functions are so similar?..
A series of question marks that we will never know. And in the subconscious, what evolves? What evolution?
It just doesn't exist. Just like we've been like this since the beginning, whether it's swimming in the water, flying in the air, running on land, ever since they took shape, these functions have been there. I wonder how we and they would survive without these instincts.
So far, there are no two similar animal, plant, and microbial species in the world, but most of them have noses and eyes that use their five senses to see the world. There is yin and yang, male and female attract, through mating, giving birth to 、..Mother's love, to achieve endless reproduction, if these functions are not naturally formed, natural, how can they adapt to the natural environment and continue?
How did these features come about in the first place? What strength is added to these animals? And nature meets the needs of these species, right?
None of this can be explained by evolution. Why are they all evolving, and only humans are evolving into intelligent beings? This shows that human beings are fundamentally different from other animals and plants on the earth, that is, everything is arranged as if animals are always animals, and human beings have been human beings from the beginning, which shows that we are probably created by some kind of intelligent civilization.
-
Because humans are very intelligent and belong to higher animals, it is also a normal phenomenon that humans are always changing and evolving.
-
This is because human beings have a relatively high IQ, and at the same time, human beings have also appeared civilized, so they can become intelligent species.

A: The first development of human evolution was bipedal walking.
Analysis: The upright walking of human ancestors was a decisive step in the evolution from Australopithecus to man. In the process of entering the orange beam, the forelimbs are freed from support and walking, and the slag lead tool can be used.
-
The common ancestor of humans and modern apes is the forest Australopithecus Wild Wheel Modern great apes include: Gorilla Spine Jun, Matsuno Shin Chimpanzee, Gibbon and Orangutan Major events in human development and evolution are: walking upright - making and using tools, further development of the brain, and the production of language.
Upright walking is the basis of evolutionary development, upright walking is a sign that human beings are free from the shackles of the forest and open up a new home, and it is the basis for using tools to make tools Because the use of tools and the manufacture of tools make the human brain more developed, language is produced in the process of labor communication
-
The upright walking of human ancestors was a decisive step in the evolution from Australopithecus to Homo. In the process of evolution, the forelimbs were freed from support and walking, and they were able to use tools to fight blindly.
-
Human evolution first developed the brain, which enabled humans to better understand and control the natural environment and thus better adapt to it.
1> In the future, human beings will be on the road to decline (The famous British paleontologist Dixon believes that the future human beings will be on the road to decline. Because from a biological point of view, natural death is a normal survival of the fittest, removing all kinds of disease-causing bad genes from the human gene pool. But today, due to the development of medicine, people who are sick can get ** and have children, so that these people will produce disease-causing genes in their bodies, and as a result, the number of bad genes in human beings is increasing from generation to generation, resulting in everyone carrying a large number of disease-causing genes, so that the physique is getting worse and worse). >>>More
The evolution of humanity is the result of a confluence of many causes. There are two main categories of causes; One is internal and the other is external. Internal causes are factors that function within human beings, and external causes are the interrelated relationships of natural phenomena. >>>More
Human beings have evolved into different skin tones and hairs because of the need to adapt to the environment. From a biological point of view, human skin color and hair color are controlled by genes. These genes are influenced by natural selection and environmental stresses that gradually alter the physical characteristics of humans. >>>More
No, because in nature, in order to survive and reproduce, living things must adapt to the rapid changes in nature. Therefore, their body shape has changed with the change of environment over the course of history. Humans are higher beings because they make and use tools, and tools replace their own evolution in nature. >>>More
As for the future, have you ever thought that human beings have a history of millions of years from primitive society to the present. From the first ape-man to early Homo sapiens, and finally slowly evolved into what it is today, the ability of humans to digest lactose in milk evolved from 10,000 years ago, and in the past century and a half, the average height of humans has increased by about 10 centimeters, and in the past 65 years, scientific progress has increased the average life expectancy of humans by nearly 20 years. Breakthroughs in science have driven the development of all mankind, from the combination of biology and technology to solutions to the water crisis. >>>More
