With bare hands, human beings are indeed a bit weak compared to animals of the same size. However, it took only a few million years for human beings to reach the top of the food chain. It is definitely not relying on Luck depends on strength, and part of strength is reflected in human physical advantages. Let's take a look at the physical advantages of human beings over other creatures.

Among the known creatures on earth today, the human brain is the smartest, and this is also the reason why human beings can reach the top of the food chain despite their weak combat capabilities. So, how powerful is the human brain?

First of all, there is a relatively scientific standard for judging the strength of an animal’s brain, which is the encephalization index, which we often call EQ (Encephalization quotient). This is based on the animal’s actual brain capacity and expectations. A value calculated from brain capacity. The larger the value, that is to say, the closer the real brain capacity is to the expected brain capacity, the smarter the animal is. However, it’s worth mentioning that this formula only applies to mammals.

Using this formula, scientists calculated the encephalization index of most mammals, and found that the human encephalization index is between 7.4 and 7.8, which is the closest to our human genes and is considered The second smartest chimpanzee has an encephalization index of only 2.2-2.5. Among mammals, the encephalization index second only to humans is the bottlenose dolphin, which has a value of 4.14, followed by the killer whale, which is 2.57-3.3, that is In terms of encephalization index, the next most intelligent dolphin is the bottlenose dolphin.

The powerful brain of human beings brings extremely strong learning, analytical and memory abilities. Among them, learning ability allows us to learn many skills and knowledge that we can use from nature, and analytical ability It allows us to conduct simulation exercises even if we are not practicing. This ability is very important. Just imagine, before humans domesticated animals, people needed to hunt, and hunting is a very dangerous job. With analytical skills, you can In the event of failure, problems can be found through brain analysis, thereby increasing the hunting success rate and reducing the chance of injury.

Memory ability is also very important, because memory not only includes smell, vision, smell, pain, hearing, but also space. Storing these memories in the brain can make people better adapt to the environment.

And this is because humans have not fully developed their brains andTaking advantage of the abilities we have, from an evolutionary perspective, we can also say that our bodies cannot bear the full development of the brain. Since human evolution is mainly based on the brain, we have reason to believe that it is possible for the human brain to be fully developed in the future. By then, human beings' abilities will reach a new level. This is one of the physical advantages that currently known earth creatures cannot match humans.

More than 3 million years ago, humans were still a kind of great ape that was not much different from other primates. Its ecological niche was similar to that of today's gorillas and chimpanzees. At that time, Australopithecus was also on the diet of many carnivores. , such as dinocats, megajaw tigers, etc. So, when being listed as one of the prey by carnivores, how did Australopithecus escape?

The first is living in groups. Living in groups is a very good way of survival. When facing strong enemies, living in groups can allow most young and strong individuals to survive and eliminate some old individuals as much as possible; secondly It’s endurance. Humans are the most endurance animals in nature.

Although in nature, humans do not run very fast, especially when compared with four-legged mammals of the same size. For example, tigers and lions can run at a speed of 60 kilometers per hour, and wild boars can reach a speed of up to 60 kilometers per hour. 45 kilometers per hour, and the speed of various antelopes can easily exceed 70 kilometers per hour.

However, human endurance is indeed incomparable to animals like wolves, which are famous for their endurance, because animals in nature are fast but have poor endurance, while slow animals have good endurance. But it is completely incomparable to humans in terms of speed. This super endurance of humans is due to humans’ unique ability to dissipate heat.

Maintaining a relative speed and running long distances requires the body to have strong heat dissipation capabilities. For example, although cheetahs are the fastest animals on land, their fastest speed can reach 120 kilometers per hour. , but this speed can only be maintained for a few seconds. This is because the too fast speed causes the body to generate a lot of heat that cannot be dissipated. If the cheetah does not stop, it will die from overheating.

The biggest benefit of human hair loss is that the whole body is covered with pores, which allows humans to dissipate heat better than any animal. This is a physical advantage that other creatures cannot compare with humans.

Seeing the flexibility, many friends will find it a bit funny, because on the surface, it seems like a feline, Mustelids are more flexible, but in fact, it is humans who are truly flexible. Of course, the flexibility we are talking about is not how far we jump or how fast we run, but the flexibility of our body joints. For example No matter how flexible cats and mustelids are, they cannot reach their backs with their claws, but humans can easily reach their backs. Even some thin beauties can touch their belly buttons with their backhands. This is the human joint. The embodiment of flexibility.

So what is the use of such strong flexibility? This is of great use. First of all, among all animals, human hands are the best at doing fine movements. Such as threading needles and threads, which is unmatched by other animals. Secondly, the flexibility of joints will reduce joint injuries as much as possible during the most strenuous exercise.

The most important thing is that human joints are flexible and can be combined into powerful weapons, and these weapons can help people kill large predators. For example, as early as January 2021, an adult female wolf broke into a farmer's house in the Jewish Autonomous Prefecture of Russia in the middle of the night and killed two There was a dog and a horse. When the farmer heard the noise and came out to check, he was jumped down by the wolf. However, he did not expect that the farmer was calm in the face of danger and used his flexible arms to strangle the wolf's neck until the wolf was motionless.

Although from the perspective of individual combat effectiveness, humans are somewhat weaker than animals of similar size in nature, humans’ smart brains, super endurance, and joint flexibility are incomparable to other animals. The latter two The first factor allowed human beings to emerge from a time when their brains were still in their infancy, and the first factor allowed human beings to step by step become the "overlords" on the earth today.
