The sperm whale s head occupies 1 3 of the body, why has it not evolved a high IQ civilization?

Whale brains can weigh up to 9 kilograms, but the number of neurons is pitifully small compared to human kilograms, the brain capacity is equivalent to that of hominids 100,000 years ago, and the IQ may be equivalent to that of children.

An important characteristic of the earth's large animals is that they have a nervous system, which can perceive the world with the help of various sensory organs, analyze their own situation, understand nature, etc., and can choose their living environment independently, detached from the way of activity that relies entirely on instinct to seek advantages and avoid disadvantages. It can be said that having a nervous system may produce a high IQ, but a high IQ does not necessarily mean that the brain is large.

A female scientist used a new method to break the brain, dissolve the cell membrane and other components with a special solution, but retain the nucleus of neurons to make a suspension, after dilution, take a few drops and put them under the microscope to count the number of nuclei under the microscope, calculate the average, and finally multiply the dilution factor and the ratio of the total amount of suspension to a drop to get a more accurate number of brain neurons.

In comparison, there are about 100 billion neurons in the human brain, which is estimated to form about 100 trillion synapses, while the number of neurons in the whale brain is only about 20 billion.

At the same time, due to the relatively large size, the ratio of the brain to the body is relatively small, and the number of neurons needed to control the movement of the body is relatively large, and the real part that can be used for thinking is much less; Similarly, chimpanzees and other species that are closer to humans have a more developed cerebellum (related to movement and balance) and a much smaller number of neurons in the brain. The characteristics of whale neurons are difficult to evolve like humans, and in the final analysis, there is no clear direction for evolution, and the emergence of "high intelligence" in humans is not inevitable.

The emergence of civilization may require a deeper understanding of nature, the rational analysis of the characteristics of nature and the use of it, but at present only human beings can use the power of nature to this extent, and it is the accidental result of environmental changes caused by various choices in human history.

This is because although the head of this animal is very large, it contains all the fat and does not have many brain cells, so it does not become a high-IQ animal.

Because they couldn't walk and could only live in the sea, they didn't evolve.

Because the environment in which the sperm whale lives is very simple, and the direction of the evolution of the sperm whale is not intelligence, it has not been able to evolve a high-IQ civilization.

In our daily life, we can often hear the elderly say that "this child has a big head and is a smart baby", which seems to be in our subconscious, the larger the brain size, the smarter it is.

The special solution dissolves components such as cell membranes, but retains the nuclei of neurons to make a suspension.

An important feature of large animals is that they have a nervous system, which can perceive the world with the help of various sensory organs, analyze their own situation, understand nature, etc

The size of the sperm whale is not suitable for high-precision work, thousands of high-rise buildings rise from the ground, and the development of any civilization needs infrastructure, and the size of the sperm whale does not meet this condition, so the sperm whale can evolve a high-IQ civilization.

The sperm whale's size is not suitable for high-precision work, and a large head does not necessarily mean that it is intelligent.

You can perceive the world with the help of various sensory organs, analyze your own situation, understand nature, etc

Female scientists have adopted a new method of breaking up the brain, dissolving the cell membrane and other components with a special solution, but retaining the nuclei of neurons to make a suspension, and after dilution, take a few drops and put them under the microscope to count the number of nuclei under the microscope, and calculate the average

However, the nucleus of the neuron is retained, and a suspension is made, and a few drops are taken and placed under the microscope after dilution.

3. Huge brain, but the available range is very strong. The last point is that although whales have huge brains, there are really very few parts that can be used for development, and about 10% of them can be used.

In our daily life, we can often hear the elderly say that "this child has a big head and is a smart baby", which seems to be in our subconscious, the larger the brain size, the smarter it is.

Although the brain volume of sperm whales is larger than that of humans, there are few neurons in it, and they are not as intelligent as humans, so they have not evolved a high-IQ civilization.

Because the size of IQ is not measured by the size of the brain, the brain of the sperm whale is 5 times that of humans, and it has not evolved a high-IQ civilization.

The most important thing is that the limbs are not very developed, and no matter how high their IQ is, they cannot create it by themselves, so the last high-IQ civilization has not been formed.

Now we understand that the ** of higher wisdom has nothing to do with the volume of the brain, only related to consciousness, that is, the structure of the brain, although the sperm whale has a huge brain, but its brain structure is too simple compared to humans, and the neurons in the brain establish very few connections, so it is not a higher creature, nor can it be compared with higher intelligence.

After all, it is survival of the fittest, and not all biological species can evolve and evolve to advanced civilizations.

Although the sperm whale has a large brain, the number of neurons is very small, and it is mostly used to control body movements, and there are fewer neurological parts to think, so it is difficult to evolve a higher civilization, and the brain neurons of humans are about 100 billion, and whales are only about 20 billion.

There are two reasons for this, the first of which is that sperm whales have five times the size of their brains, but they have only one-fifth the number of neurons of humans. The second reason is that sperm whales are much larger than humans, much more than five times larger.

Because the intelligence of living beings is not determined by the size of their brains, although the brains of sperm whales are large, they cannot evolve into advanced civilizations.

Although the head of the sperm whale occupies 1 3 of the body, most of the space is a lump of oil, a real oil, yellow, translucent.

Because the environment in which it lives cannot evolve a noble civilization!

A large brain size does not necessarily mean that it will be smart, mainly because the living environment does not need to evolve to a high IQ.

His body is all fat, he can only live in the sea for the rest of his life, and what IQ does he need.

A big head doesn't necessarily pretend to be something with an IQ.

I'm telling you that it's because the sperm whale's brain is "in the water."

Because there is no gene and necessity yet.

Although their brains are large, they do not occupy a large proportion of their bodies.

This is because their brains are not highly developed.

In our daily life, we can often hear the elderly say that "this child has a big head and is a smart baby", which seems to be in our subconscious, the larger the brain size, the smarter it is.

The generation of higher intelligence has nothing to do with size, but with the degree of development of the brain.

I don't think it has anything to do with the size of the brain, as long as it has to do with the degree of development.

I think it's because the brain of sperm whales is not well developed.

I think it's because the intelligence of living things doesn't depend on the size of the brain, but on the degree of development of the brain.

This has nothing to do with the degree of brain development, not the size of the brain.

The sperm whale's brain is not well developed, and it has nothing to do with volume.

Personally, I think that the degree of intelligence depends on how well the brain is developed, not the size of the brain.

Wisdom does not depend on the brain, but on the degree of development, otherwise the big head is smart

It mainly depends on the degree of evolution, and it has nothing to do with volume.

Scientists are most interested in the sperm whale for its peculiar large head. There are a variety of opinions on this.

Some people believe that the fat in the head of the sperm whale plays the role of an echo detector. The sperm whale eats a lot, needing an average of 300 kg per day, and it not only hunts during the day, but also eats at night. The sperm whale's diet is mainly octopuses and giant squid, and in the noisy marine world, if you do not use echolocation to detect the location and number of prey, you will not be agile and fast.

The fat in the sperm whale's head is like a lens in acoustics, refracting complex echoes into sensitive detection beams that are transmitted to the ear, so that the brain can make quick and accurate judgments.

Some people disagree with the above statement, thinking that the sperm whale has so much oil in its head for diving. Because the sperm whale's food source, octopus and squid, or squid, all live in the deep sea, it must dive for a longer time in order to catch more food, and the oil in its head acts as a buoyancy regulator. Who is right and who is wrong in these two claims remains to be further studied.

Everyone knows that the sperm whale, the largest animal in the sea, is an aquatic mammal. It breathes with its lungs, inhales at the surface of the water and dives into the water, where it can swim for up to 1,045 minutes. For a long time, people have explained the ups and downs of this animal, believing that it is mainly caused by the reduction of the specific gravity of its body by a layer of fat under it.

Recently, scientists have specialized in studying the physiology of sperm whales. They are deeply interested in the head of the sperm whale: the sperm whale has a world-record large head, and its head accounts for 1 3 of its total body weight (60-100 tons).

These pets feed on zooplankton, molluscs and fish. It likes to eat horsetail the most, and this nimble fish grows in the deep sea. In order to hunt the horsetail, it is necessary to have a high level of diving skills, not only not to scare away the prey, but also to hide itself, which means that it is necessary to lie motionless on the bottom of the sea for half an hour.

This lurking is completely balanced by buoyancy, which requires the sperm whale's body density to be the same as the density of the surrounding water. Sperm whales have such huge heads just to adjust their body buoyancy. Dissecting this giant revealed that the volume of 9 10 was a kind of "cetamine tissue", a "big bag" of muscle and mesangium, filled with a type of cetacean wax in the form of a liquid.

It has been tested that the temperature of this "cetamine tissue", which has blood vessels passing through, often remains lower than its entire body temperature3, which is very useful. When the sperm whale dives into the deep sea, this special "heat exchanger" comes into play.

Its right nasal cavity, which penetrates deep into the skull (which is completely different from the left nasal cavity), becomes a muscular cavity that connects to the "cetywax tissue". The seawater flowing into the "cetacean wax tissue" through the nasal cavity not only plays the role of "pressurized water" in a submarine, but also reduces the temperature of the cetacean wax to its crystallization temperature———31, so the volume of the cetacean wax decreases, the density increases, and the body density of the entire sperm whale increases. The researchers noted that the sperm whale's big head actually functions as a swim bladder in other fish.
