Another reason is that I currently possess some of the virtual power of the Void Emperor, which allows me to understand all of this instantly. For example, the timid character of us humans was born in this era, and was then memorized in the DNA.

, so if we modern humans feel that we are timid creatures, I think, right? This is a bit excessive. After all, we are such creatures ourselves, and there is no need to be ashamed of it.

This group of big rats who are about to evolve into humans are absolutely desperate at this moment. It is a frozen world outside, the weather is freezing, and there is not enough food in the cracks of the rocks. It is usually some relatively small insects.

But this is not enough for all of our human ancestors to survive.

And the large animals outside, whether it is the Tyrannosaurus rex that is not dead yet and is making its final struggle, or the pterosaurs or even the mammoths or any other animals, they all have absolutely overwhelming power and can be killed very, very easily.

It could kill and eat our human ancestors.

Therefore, our ancestors hid because of fear. This was the most correct thing to do. Although in this process, we would not be able to raise more children, which was inevitable. This was a situation of food shortage, so having too many children meant that

The weak ones must be killed. Another problem is the ability of our ancestors. During this evolution, our ancestors obviously did not have the teeth and bite force as powerful as Tyrannosaurus rex, let alone the sharp claws of Tyrannosaurus rex, nor the

The wings used for flying like a pterosaur cannot have the huge size or even the absolute lethality like the saber-toothed tiger.

So our human ancestors really look a little pitiful, and this pitifulness has lasted for nearly a thousand years. This is no joke. Imagine if a group of rats were severely lacking in food and even faced enemies from all sides.

, it is such a difficult process to survive and reproduce in the cracks of stones for thousands of years.

And during this thousand-year freeze, our ancestors made full use of their timid character, hiding in the cracks of stones, and facing more threats, such as snakes and others.

Some small animals that could kill him survived so strongly and multiplied until the time when the earth warmed up thousands of years later.

In the past thousands of years of ice, many ancient animals on the earth were not completely extinct. Some of them survived strongly, mainly because they migrated to find more suitable places to live. This is one of the factors. Of course,

There are other factors, such as luck, but whether it is migration or luck, the most important thing is the food source. Without food, everything is empty talk.

Anyway, this ice age will definitely be a devastating blow to all species on the earth! But the reason for everything is just an accident of a comet hitting the earth. I don’t know if the comet contains some kind of strange substance.

Anyway, after thousands of years, the species on the earth have undergone some relatively big changes.

For example, many animals have evolved fur that can keep out the cold. Of course, our human ancestors also had it, but they are not as warm as other animals.

Time flies, and on our planet, everything happens in an instant.

…

In the end, our human ancestors survived strongly, and evolved from animals like mice into species like monkeys, and there is not only one species. In fact, our current human ancestors are the same as chimpanzees, even baboons, and even

Elephants and the like don't seem to be any different. They are all competing for territory, but we humans are obviously not as powerful as chimpanzees or baboons or even elephants.

There is a reason here. We humans actually have a huge flaw. Why do we say this? Because the only difference between us humans and other animals is the brain problem. Generally speaking, for a 60-kilogram mammal, the average brain capacity

It is only about 200 cubic centimeters, but the ancestors of humans in our era had brain capacities as high as about 600 cubic centimeters. Even our modern humans in the 20th century have a maximum brain capacity of about 1,300 cubic centimeters.

From this point of view, it seems that according to the evolutionary history of natural selection, we humans should be smarter than other animals. Unfortunately, this is definitely not a good thing for our ancestors, and why are we the only ones

Why did humans evolve such huge brains?

According to Xuhuang’s thinking logic, our human ancestors should have had random thoughts out of fear when they were mice, thus promoting the evolution of the brain. But why do I say that this is not a good thing for our human ancestors? Because

The bigger the brain, the more energy it consumes. Even when our ancestors were sleeping, the energy consumed by the brain accounted for about 25% of the energy consumed by the whole body, which prompted our human ancestors to spend

More time is spent looking for food, followed by muscle degeneration and atrophy. This is like a village in our modern human world in the twentieth century that allocates funds to education, and then other causes are relatively ignored. This is

There is a truth. So our human ancestors deprived the brain neurons of the energy required by the biceps, but this approach is obviously not good. For example: currently a baboon and our human ancestors want to reason, but they can’t reason with us.

Ancestors, but when it comes to fighting, baboons can easily tear our human ancestors into pieces in an instant, just like tearing toilet paper.

Moreover, the brains of our human ancestors have been growing and have never stopped. This growth has lasted for nearly two million years. How terrifying this is. What is even more terrifying is that the brains of our ancestors have grown in the past.

Such crazy growth for more than two million years has not brought any substantial use. For example: during these more than two million years, our ancestors only used their developed brains to make stone knives, and then used them.

The stone knife sharpened the branches.

Therefore, our human ancestors did not live very well during the more than two million years of brain evolution and growth. It can be said that the fearful character was deeply implanted in the DNA, because almost any animal has the ability to kill easily.

To kill our ancestors, our ancestors must always live in hiding, such as hiding in caves. Even the food is not hot. Usually other animals eat the leftover animal bones or even carrion, and then

Our ancestors would break the bones with stones and eat some of the marrow inside to maintain the body's energy needs.

And our ancestors have another characteristic, that is, they can walk upright. Why should we walk upright? In fact, the answer is very simple, because we need to collect fruits from relatively tall trees, mainly to do other actions, so standing upright is a good choice. Of course,

Our ancestors also paid a huge price for learning to walk upright.

First of all, because we have to walk upright, our ancestors' bodies will constantly make corrections to the neurons of the brain, and also to the muscles of their hands and fingers. This makes our ancestors' hands more dexterous and can handle some tasks.

Precision tasks, such as making tools, such as sharpening a branch with a stone knife.

However, although walking upright brings benefits, it also brings disadvantages. In fact, it took millions of years for our human ancestors to learn to walk on all fours. Therefore, the head frame is relatively small, but now suddenly

It can be said that adjusting this kind of skeleton to walk upright is basically a challenge that is as difficult as climbing up to the sky, and it has to support an oversized skull, which is even more difficult than climbing up to the sky. So until the present in the twentieth century,

In order for us humans to have flexible hands and see far, we can only bear the price of back pain and stiff neck.

Another one is the impact on our female ancestors. Because walking upright requires narrowing the buttocks, the birth channel is affected and becomes smaller. However, due to the evolution of the brain, the head of the fetus is getting bigger and bigger.

Therefore, women of our human ancestors had a very, very high risk of giving birth, and their mortality rate was particularly high.

But natural selection has made corrections to the aspect of female birth in us humans. It can be said that at this time, all the children of our human ancestors were premature babies, because premature birth means that the fetus’ head is small and soft, so we humans

The mortality rate of female ancestors is reduced, and they can continue to have children in the future, but this does not seem to be a good thing for the fetus.

First of all, some other animals are not like this at all, such as sheep. Lambs can actually walk not long after they are born, because their organs and other organs are already formed. Besides, today in the 20th century, we humans like a pet.

Cats are animals that can leave their mothers and even hunt for themselves when they are only a few weeks old.

However, the organs of our human fetuses are not formed at all, which is inherently premature. Therefore, human fetuses are not very useful. They can only be protected and raised, and they have to be instilled with knowledge, even if they are protected and raised.

, and any small accident may cause death.

The other one is our human children. The difference from other animal children is here. Other animals give birth to children. It is like the glass bottles made by a certain factory in our current era. They have been formed and shipped out of the factory. If we want to change it

Some parts of it are bound to cause harm. But we human children are different. When a human child is born, it is like unformed molten glass in a glass factory. It can change some shapes at will. So in the end, we modern humans have

Different personalities, for example, some people like peace, some people like killing, some people believe in Buddhism, while others like Taoism, some people want to be astronauts, while some people just like to eat, drink and have fun...like me? I just like to go

Japan, the land of fireworks, is my greatest dream!

But having said that, children can be a drag on our female ancestors, because when they go out to look for food or something, they have to take them with them. If you don’t take the children with you, the child’s mortality rate will be at least 99%. Another one is
