Why do horses run when they are born, dolphins can swim when they are born, and can humans do it?

There are abundant animals living in nature, I don't know if you have noticed such a phenomenon, many mammals are born after the young can run and stand immediately, such as fish and marine life in the sea is also in this condition. Although humans have become the rulers of the earth in the midst of cruel competition, and have mastered advanced science and technology, why can't human babies walk upright right away?

The evolution of the brain.

The process of evolution is the process of selecting excellent genes, and the reason why human beings have survived and reached their current status is inseparable from the brain. We are able to survive on Earth because of our brains. When a baby develops in the mother's womb, it is also the developing brain first.

When we see a lot of newborns, we will also find that their head proportions occupy a large part, and if compared with creatures in nature, the time for human pregnancy is still relatively short. In such a short period of time, the level of human development is naturally inferior to theirs, and most of the energy absorbed by babies is used in the brain, while animals divide this energy evenly among each part and organ.

The lifespan of the animal.

In addition to this factor, we can see that the lifespan of animals in nature is not the same, but most of them are shorter than the human lifespan, so in the limited life, they must master the level of independent living in the early stage. Because they don't have enough time, they must have the ability to survive and reproduce from an early age, and human lifespans are getting longer and longer, thanks to advances in medical care, humans may break the age limit of 120 years in the future. It is with enough time to survive that we are able to get better step by step.

Why do dolphins and horses swim and run after birth?

Scientists have also done research on many organisms in nature. A foreign film company once made a real-time report on the situation of dolphins in their maternal development. They found that the dolphin was only 8 weeks old and was able to swim in its mother's womb, 10 months before giving birth, and in the next few weeks, it gradually grew a tail and a head, and in order to adapt to the environment, it had to learn the skill of swimming in the mother's womb.

They also track the birth of horses. When the female is 12 weeks pregnant, the young horse has already developed its form, and in the following time it begins to exercise its leg muscles, gradually grows ears, and after a long period of exercise in the mother's body, it is naturally able to walk after birth.

Of course, this is not to say that humans are inferior to animals in this aspect, this is because human development focuses on the brain, after all, with the support of the brain, we can create a higher civilization.

Humans cannot. It has to do with the human brain.

The human brain needs to be selectively "pruned" to remove the cranial nerve connections that are considered redundant and strengthen the cranial nerve connections that are considered useful. And this process is slow, so humans are usually not necessarily able to stand up after a few months of birth, let alone walk and run, unlike some animals who are born and can run a few hours after birth.

It is impossible to retain all the connections of human cranial nerves, and the human body is not so much. From birth to adulthood, cranial nerve connections are reduced by nearly half. Why do we have so many cranial nerve connections that we don't need in the first place?

The reason is that the human world is ever-changing, and people don't know what kind of world they are facing at the beginning, and they need to adapt to the environment through the screening of some abilities the day after tomorrow.

There is no essential difference between the human brain and the brain of other living beings. The brain is not actually a thinking organ as we generally think of it. This is a question about how the brain works, so I'll omit it here.

Because that's the nature of every animal, humans can't, humans are born without moving, they can't even blink their eyes, but over time, they can walk, jump and think.

Humans cannot, this is the result of biological evolution, nature has given each creature different survival skills, survival of the fittest.

Yes, but it's not the same as them, for example, the reflex is something that people are born with.

It's actually quite simple, all of our actions now are controlled by that part of our body?

The reason why we walk wakily when we are children is precisely because the part of the brain that is responsible for controlling the movement and balance of the body is not yet fully developed.

Therefore, newborn babies still need to grow for a while, wait for the brain to develop a little bit, and then slowly start to learn to walk. But like lambs, calves and ponies, they have already matured the part of their head that controls body movement and balance in their mother's womb.

So they can walk as soon as they're born.

First of all, let's figure out that the biggest difference between humans and calves and ponies in the "walking" area is that humans walk on two feet standing up, while calves and ponies walk on four legs.

But in fact, human beings also walked on four legs, and in order to adapt to the living conditions, human beings gradually evolved to walk on two legs, and at the same time, the structure of the body has also undergone some changes.

Originally, if the mother walked on four legs every day, the place where the mother gave birth to the child was larger, so the child's head was allowed to further mature before being born;

However, after walking on two legs, in order to adapt to this habit, the bones of the buttocks become narrower and the nearby muscles become thicker and stronger, resulting in a smaller and smaller place for the mother to give birth.

In this case, what will happen if you are still walking on four legs, waiting for your baby's head to further mature and be born? That's right, such a life can't come out.

Hence the saying that humans are "premature".

In fact, from an evolutionary point of view, the reason why humans dominate other races and stand at the top of the food chain. There are three main reasons, one is the human brain, for the human brain is highly developed, one of the main manifestations is the change in brain volume. Also a primate, the human skull has a capacity of 1500 ml, which is twice the brain capacity of macaques, gibbons, and chimpanzees.

When a baby is conceived by its mother, it is actually the brain that develops first. When we observe it, we will also find that after the baby is born, it will feel that the head occupies a large proportion of the whole body. Among mammals, the pregnancy time for humans is actually very short, dolphins have a pregnancy cycle of 15-18 months, while horses have a pregnancy cycle of about 11 months.

For humans, it is calculated on a 28-day cycle, a 10-month gestation cycle. In terms of length of time, the gestation time of humans is shorter than that of other mammals, and the degree of natural development is not as good as that of other mammals. In the mother's womb, the energy absorbed by human babies is mainly used to develop the brain, and other mammals distribute the energy evenly among the parts.

The second is that it can walk upright, and the gene has chosen this advantage, which must also pay a corresponding price. From a kinematic point of view, if you walk upright, the hip joint becomes narrower. In other words, for women, this advantage also means that the birth canal is narrowed, and for a long time in the past, there was no caesarean section, and death in childbirth used to be a great risk for women.

The third is the problem of lifespan, cats and dogs have an average lifespan of more than ten years, except for humans, most mammals do not have a lifespan of up to 70 years. Therefore, they can only compress their growth period to quickly reach the level of independent life, complete the purpose of birth, development, and breeding, for example, the sexual maturity period of horses is only 18 months.

01 The status of humanity.

At present, humans have long been at the top of the food chain, so even if humans are not comparable to most wild animals in terms of size, they still do not need to worry about threats from wild animals. Moreover, human beings have long had the ability to build shelters, and the creation of shelters can provide people with a relatively safe living environment. Therefore, the status of human beings now no longer needs to be able to stand and run like wild animals on the "starting line".

02 Breastfeeding.

Due to the relatively high position of the food chain and the guarantee of safety, humans are no longer passive lactating like wild animals, but actively breastfeeding, and most people can only give birth to one litter, and there is no competition for the baby itself. Therefore, there is no need for them to actively strive for something from birth.

03 The lifespan of an animal.

Most wild animals have a lifespan of between 20-40, and more than 40 is considered a long-lived animal, so they can survive for a relatively short time, so their growth rhythm needs to be fast. Unlike human beings, the average life expectancy of human beings is about 75 years old, and there is enough time for humans to grow and develop in the juvenile period, so most animals reach adulthood at the age of 2-3, while humans need to be 18 years old. Therefore, the lifespan also determines the growth rhythm of the animal.

Modern radar – a radiolocation and ranging device: Scientists have discovered that bats rely not on their eyes, but on an echolocation system consisting of their mouth, throat and ears. Since bats announce ultrasound waves when flying, they can also detect ultrasound waves reflected back from obstacles.

Scientists have developed a modern radar – a radiolocation and ranging device – through the study of dolphins' low resistance to swimming, they have created artificial dolphin skins that can improve torpedo speed; and wheelless cars (jumping motors) that mimic the way kangaroos move in the desert. Inspired by penguins, scientists from the Institute of Zoology of the Academy of Sciences of the former Soviet Union planned a new type of car, the "Penguin" brand polar off-road car. The wide bottom of the car, which is directly attached to the snow, is propped up by wheels and spoons and can travel at speeds of up to 50 kilometers per hour.

Scientists have built space robots modeled after insects. A team of researchers at the Australian National University has developed a small navigation and flight control device based on the study of several insects. Such equipment can be used to equip small hoverboards for Martian surveys.

British scientists, inspired by biomimicry, are developing a submarine that can "swim" in an S-shape by swinging its tail fin, and the main difference of the new submarine is the use of a device called an "elephant trunk actuator". The "trunk" consists of a set of hoses made of thin, soft material that mimics muscle activity and pushes the movement of the fins. This new type of submarine can be used as an underwater minesweeper to defend against mines that can be detonated at the slightest movement or disturbance.

The nasty flies seem to have nothing to do with the majestic aerospace industry, but biomimicry binds them together. Flies are the "stinking husbands" of disrepute, but they can be found in all filthy places. Flies have a particularly active sense of smell and can smell even from thousands of meters away.

But the fly does not have a "nose", so what does it rely on to fill its sense of smell? Originally, the fly's "nose", the olfactory touch, was scattered on a pair of antennae on the head. Each "nose" only needs one "nostril" to communicate with the outside world, and contains hundreds of olfactory nerve cells.

If an odor enters the "nostrils", these nerves immediately convert the odor effect into nerve electrical impulses that are sent to the brain. The brain can distinguish different odor substances according to the different nerve electrical impulses of different odor substances. As a result, the antennae of the fly resemble an active gas analyzer.

The reason why human babies are born will not be the result of biological evolution, the evolution of animals is related to the living environment, in order to survive when the environment is harsh, animals must master certain survival skills, such as many cloven-hoofed animals can stand up a few minutes after birth, and can walk away after a few hours, which is created by the living environment, because if it can't walk or run, it will be eliminated by natural enemies and cannot survive, and human beings are different from other animals, and human beings are relatively safe and comfortable to survive. The lifespan is also longer than that of other animals, so the rate of growth and development is slower than that of animals, and many skills are slowly learned in the process of growth and development.

In fact, the way humans and animals learn survival skills is very similar, they are learning from their parents in the process of growing up, but because the average life expectancy of people can reach more than 70 years old, and the life span of animals is often only more than ten years, humans can learn skills in decades, but animals can only have a few years at most ten years to learn, so the speed of animal learning is faster than that of humans, people need to learn to walk in 12 months, but animals can use a few hours, if animals and people need to learn to walk in more than ten months, then it will not be able to survive, so in fact, not only human babies are born with nothing, but also the young of other animals are born with nothing, but the length of time to master skills is different, and all this is created by nature.
