Can humans evolve Can humans still evolve

As far as the human gene pool is concerned, humans have always evolved: traits that are not adapted to the environment are constantly being eliminated, and adapted traits are constantly being retained. It's just that in some cases the influence is greater by the human beings themselves, for example:

Many people in Europe regard blonde hair and blue eyes as beautiful, so it is easier for blondes to get mates; I am afraid that many people in society have wanted their wives to have a delicate body that meets social standards, needless to say, people with this condition must easily pass on their various traits to the next generation These are some obvious examples So why do people change so little in a short period of time? Genetic mutations in any population have two properties: non-directional and infrequent Among the few mutated individuals, many of them cannot be inherited

Some happen to be somatic mutations, and some produce mutations for infertility. Therefore, it is really more difficult for those so-called genes that can change the whole person to be inherited and completely occupy the mainstream position in the human gene pool. You can't do this job without tens of thousands of years.

It's easy to understand why people are still so majestic for thousands of years!

If the environment changes dramatically, humans will evolve or become obsolete if they don't adapt.

Inevitably, however, due to modern technology, the rate of evolution will slow down a lot ......

No, there are no evolutionary conditions anymore.

Our teacher said it.

In fact, the theory of evolution is not clear.

Throughout recorded human history, the evolution of the human body has been minimal, and it is difficult to say that there has been a relatively significant evolution in such a broken time.

From the perspective of development, the natural law of survival of the fittest and natural selection will inevitably promote the evolution of human beings.

You live longer, you'll know in tens of thousands of years!

Humans can evolve and fast. Scientists in the United States have found that about 1,800 genes in the human genome are in a state of accelerated evolution, which accounts for about 7% of the entire human genome. Narrow reproductive bottlenecks and sudden bursts of population growth have contributed to a new wave of genetic variation.

The latest research shows that the rate of human evolution has actually accelerated by a factor of 100 over the past 5,000 to 10,000 years, and the pace of evolution has been so rapid that the changes in the human body and mind have been more pronounced than in any recorded period of history. And, this evolution continues.

Introduction to Human EvolutionHumans and apes are related in some way and share a common ancestor. About 65 million years ago, a large meteorite with a width of about 16 kilometers hit the Yucatan Peninsula in today's Mexico, creating a huge disaster, when two-thirds of the animal species on the earth, including dinosaurs, died out and became extinct, and the ** era of reptiles ended, and primitive mammals escaped the catastrophe after a long time of survival, and then quickly went into the wild.

Human evolution originated from forest apes, and developed step by step from primates through a long evolutionary process. It has gone through four stages: ape man, primitive man, sapiens man, and modern man. Due to the development of archaeology, prehistoric civilization has been gradually denied, and archaeology has most of the evolved hominin fossils.

In conjunction with the discoveries of modern biology, it was discovered that genetic DNA is evolutionary, confirming the authenticity of the theory of neutral evolution.
