Wisdom tooth. One of the unwanted things that humans have evolved must mention is wisdom teeth. As a young man, a young man, I was very depressed when I found out that I was starting to have wisdom teeth.
But the reason that makes me most frustrated, you probably don't expect, because I am not afraid that wisdom teeth will be inflamed and painful, nor because wisdom teeth will make the masseter muscles bigger when they grow, nor because it will hurt to extract wisdom teeth, but when I know that as a young person, I actually have wisdom teeth as if my genes are inferior, and I have evolved not as good as others. <>
As we all know, our human food is getting thinner and thinner, from the previous grains to the current golden grains, rice is becoming softer and glutinous, noodles are thicker and finer, and most foods are becoming easier to digest. As a result, very hard wisdom teeth, which humans may have developed to chew some indigestible food, have gradually been eliminated in the process of evolution. For example, someone once committed suicide because of wisdom teeth, because wisdom teeth are connected to human nerves, and if the tooth extraction is not good enough, it may lead to facial paralysis.
Like me, the relatives around me, all of my peers do not have wisdom teeth, only I have them, and I have 4 of them. Tell me what he brought me. The process of growing the first wisdom tooth is really painful, because it is inflamed at every turn, and after the inflammation, it is like the tonsils are inflamed, which makes me sometimes wonder if I have a bad cold, why my throat hurts so much, and sometimes I wonder if there is a big mouth ulcer near the throat, which is why it hurts, and then I came up with the answer under my observationWhat makes me so painful is the growing and inflamed wisdom teeth, and the extraction of wisdom teeth can also be expensive, it will cost a lot of money, and there is a lot of risk, which is why the salary of dentists is so high.
And before the wisdom tooth extraction, it is often necessary to take a photo, otherwise it is not certain whether the tooth can be extracted. <>
All in all, wisdom teeth in modern times will only cause people pain, and it will take a lot of time and money.

In fact, it is not necessary to have wisdom teeth at all, many of us will find that wisdom teeth will grow later, but wisdom teeth are very troublesome, they have no practical value, and they will easily cause toothache, and they also need to be extracted later, so this is a manifestation that evolution is not as good as net evolution.

Body hair, I don't think body hair should exist, because in the evolutionary history of human beings, human body hair has gone from existence to nothing, and now there is luxuriant hair, and I personally think this series is completely unnecessary.

What can be evolved is useful, and the functions of evolution are indispensable and necessary for us.

The factor that played an important role in the evolution of humans is walking upright.
Paleoanthropologists see upright walking as an important factor in human evolution and an important symbol of human birth. For example, the inevitable consequence of walking upright is the division of hands and feet, which allows humans to use tools flexibly.
Another example is that after walking upright, the field of vision is broadened, which helps the development of the brain and promotes the development of human intelligence. Because human beings have highly developed brains, aesthetic concepts, coupled with human desire for self-expression and relatively large brains, human beings have created language, religion, art, and science.

c. This question examines the relevant content of human evolution. Science has proved that humans evolved from apes, and in this evolutionary process, the use of fire, walking upright, labor, and the use of writing all played an important role, but the most important role was labor. c correct.
Therefore, C is selected for this question.

Wisdom is not the clear direction of the evolution of life on earth, what is the ultimate purpose of biological evolution?
-
I believe that the ultimate goal of human evolution is to rule the earth, to make humans the masters of the earth, and to make the earth more vibrant.
-
The purpose of human evolution is to survive better, and there is no ultimate goal, just to perpetuate genes.
-
I believe that the ultimate goal of human evolution is survival, survival is the ultimate goal of all living things, and the ultimate goal of human evolution is also like this, that is, to survive better.
The important symbols of human evolution are: walking upright, using fire, language, grazing and farming, inventing muskets, and using electronics. >>>More
It is understood that this year is the 2.5 million year of the birth of our human beings, and human beings also evolved from a fish in 2.4 million years, which has countless doubts in almost everyone's minds. However, in 2017, Chinese scientists published ** to confirm that human beings are not a fish, but a primate, and also a mammal of great scientific significance. >>>More
The theory of evolution was put forward by Charles Darwin, natural selection, survival of the fittest, and humans evolved from close relatives of our earliest ancestors, apesAfter five or six million years of development, there are now human beings, but some people have questioned whether Darwin's theory of evolution is right? <> >>>More
No. The growth and development of animals and humans both start from a cell, that is, the human body is developed from a fertilized egg, and the composition of ** and muscle cells are very different in structure and function, which is due to the result of cell differentiation. Besides, the ancestors of human beings evolved from apes.
