Why do humans walk, and why do humans walk?

For a long time, walking upright was considered one of the signs of human existence, but there have been many opinions in the academic community about how people "stand up". A new study by American scientists has found that walking on two legs consumes only a quarter of the energy of a chimpanzee walking on all fours, and it is much less labor. This may explain why our ancestors ultimately chose to travel on two legs.

Humans vs chimpanzees Walking is more energy efficient.

According to the British "Independent" on July 17**, anthropologists from the University of Arizona and other institutions in the United States selected four human volunteers and five chimpanzees as research subjects. By measuring the amount of oxygen they consume while traveling on the treadmill and the force they exert while traveling, the energy they each use is calculated. It was found that the gait of a man walking on two legs saved 75% of energy compared to the gait of a chimpanzee walking on all fours.

This finding is a strong case for the establishment of an upright way of walking in humans that is related to energy expenditure, and that it requires less food. "Researchers have debated for decades about the role of energy consumption in the evolution of upright walking," said Richard Richlen, a professor of anthropology at the University of Arizona.

But the problem is that there is little strong evidence to support this idea in the past. ”

Chimpanzee vs Chimpanzee Stride more efficiently.

The scientists also studied and compared the energy consumption of chimpanzees in the asynchronous state. Overall, there is little difference in the amount of energy used by chimpanzees to walk on two hind limbs or on all fours, however in individuals, some chimpanzees are more energy-efficient than walking on all fours, some are similar, and some use more energy, depending on the size of their stride, the larger the stride, the more energy-efficient.

"We linked the energy consumption of chimpanzees to their bone structure, and through biomechanical models, we found out why some chimpanzees are more energy-efficient when they walk bipedally than their peers......This difference is surprising and exciting, because when it comes to evolution, difference is the most critical, and there is no evolution without difference. ”

The team believes this could uncover the secret of the gradual lengthening of the legs of early human ancestors during evolution. If an individual can exercise and hunt in a more energy-efficient way, and save more food, new species will evolve according to the theory of "survival of the fittest". These experiments and studies have shown that energetics played a very important role in the evolution of bipeds.

In short, it's about reducing physical exertion. At the same time, people can walk may be genetic mutations, lesions, just like people's genes because of the lack of two letters (of course, it is a reference, I don't know what it is) makes people's frontal muscles shrink, so that people's brains can get enough space to develop.

The result of a long evolution.

Summary. Why do people walk:

It can be explained in terms of both evolutionary chemistry and physiology.

1 Evolution, human evolution is to enhance the adaptation to the environment, and choose the path of brain evolution, the improvement of intelligence is first manifested in the application of tools, in order to effectively use tools, the change of hand function is necessary, so the hand becomes more flexible and small and loses the function of supporting the body, so the foot must fully assume the responsibility of supporting the body, and the functional characteristics of walking on both legs are realized in evolution.

2. In physiology, the changes in the bones caused by human evolution have completely formed a skeletal form dominated by standing, which is mainly manifested in the differences in the bone morphology of the upper limbs and the bones of the lower limbs, the changes in the structure of the hip joint, and the changes in the connection between the occipital bone and the cervical vertebrae. As a result of these structural changes, people are never fit to crawl, but only to walk.

Can you walk.

I can walk. Walking, since I learned it as a child, I haven't forgotten how to walk, and I still walk.

Because humans evolved from apes, they slowly became straight and walked, and humans are also advanced animals, so it is said that human brains are very developed, and they use their brains for everything.

Because in ancient times, ape-man lived in trees, but soon the woods were destroyed in large numbers, and ape-man was forced to live in the ground, and because man evolved from ape-man, man can walk.

Yes......You must be able to do the most effective way, just say it at a time, care about what you think so much, or it is that he uses it to think about others and find a way to give people respect for themselves and their families.

This history begins with the evolution of human beings, in order to adapt to survival. It's the same with children.

Humans evolved from apes and slowly got used to walking upright, so they ......

Because people have short upper limbs and long lower limbs, they are uncoordinated when they walk on all fours.

Because people are born to go!

There can be a variety of explanations for why some people walk fast, here are some possible reasons:

Personal habits and personality: Some people are naturally accustomed to walking quickly, which may be related to their personal personality. Some people may be naturally energetic, active, and prefer a fast-paced lifestyle, so they also show a faster pace when walking.

Time pressure and purposefulness: Some people may walk fast because they are under time pressure or have urgent tasks to complete. They want to get to their destination as quickly as possible, so they will speed up their pace.

Fitness and staying active: Some people choose to walk briskly to keep their bodies fit and active. Brisk walking is considered an effective aerobic exercise that can lead to improved cardiorespiratory fitness and calorie burning.

Living environment and cultural factors: Some cities have a faster pace of life, and people are generally accustomed to walking quickly. In such an environment, in order to adapt to the fast-paced life, people may speed up the pace of their stupid spring type.

Personal habits and training: Some people may have been trained and used to it over a long period of time, allowing them to walk at a faster pace. For example, walking for a long time or participating in activities such as race walking can develop a faster walking speed.

It is important to note that the speed of walking varies from person to person, and there is no absolute standard for Moriyama. Everyone's stride length and pace can vary, depending on physical characteristics, habits, and personal preferences. The important thing is to choose a pace and speed that suits you, and to stay comfortable and healthy.

Summary. Although walking is one of the most basic human activities, many people do not have proper posture and are prone to physical discomfort and even injury, probably because few people are taught how to walk properly. In addition, many people usually wear shoes that are too soft, lack support and care, and affect their walking posture; Sitting and not exercising can also lead to joint stiffness and poor posture.

Therefore, we should pay attention to the correct walking posture and exercise properly to protect our health.

Excuse me, but please go into more detail?

Summary. Most people don't walk properly, mainly because they don't master the correct gait. Correct gait can not only improve the efficiency of walking, but also reduce the burden on the body and prevent injuries.

However, due to the lack of proper gait training, most people do not have a correct gait, their gait is irregular, their steps are unsteady, their bodies are uncoordinated, and they are prone to injury. In addition, most people have weak leg muscles due to a lack of exercise, and insufficient leg muscles can also affect the correct gait. Therefore, in order to walk correctly, it is necessary to go through the correct gait training, strengthen the leg muscles, and exercise more to achieve the correct gait.

I'm still a little confused, can you be more detailed?

There are many reasons why most people don't walk properly, the most common of which is a lack of adequate exercise. Since many people in modern life don't have enough time and energy to exercise their bodies, their leg muscles tend to be very loose, which leads to them not being able to control their leg movements properly, which leads to them not being able to walk properly. To solve this problem, the first thing to do is to increase the strength and flexibility of the leg muscles.

Leg muscles can be strengthened by doing some simple leg exercises, such as squats, jumps, leg raises, etc. In addition, walking skills can be improved by practicing proper walking posture, such as keeping your body steady, legs relaxed, steady steps, waist straight, head elevation, etc. Finally, it is important to remember that in order to walk correctly, you need to practice regularly, and only through repeated practice can you make your leg muscles stronger, so that you can better control your leg movements, so as to achieve the goal of walking correctly.
