The judgment of the old apes saved the lives of the tribe in the early stage. Hiding in the rocks in time could avoid being swept away by the flood or drowned by the mudslide, but at the same time it cut off the escape route of the tribe.

Evacuation became a fantasy.

The apes at that time did not have the knowledge to build a boat.

Tie to a piece of wood and drift with the current to see where you can drift to, leaving everything to luck?

This idea seems beautiful, but there are actually many problems.

First, there were no ropes at that time, only rattan. Rattan is OK for dragging things, but it is difficult to fix it firmly when used to tie people, and the tied people can easily slip off.

Second, there are not enough rattan, and it is not enough to save a few people.

Third, this is a bare rock mountain with few trees.

Fourth, in a raging flood, even if a person floats holding onto a tree trunk, he or she can easily be buried in the water and drown.

In summary, this is not an idea with a high survival rate and is extremely unfeasible.

Even if a few people can survive, the tribe no longer exists.

There is no chance of survival for a lone ape to enter the wild.

Even with Chen Feng's intelligence and modern people's knowledge, he can't think of how the primitive humans trapped on the top of the mountain can escape.

Therefore, although they know that staying on the mountain will only lead to death, the surviving apes have no choice but to live one day at a time.

The virtual history in front of Chen Feng is slowly accelerating.

As time went by, as food became increasingly scarce, the apes' living habits and body shapes began to change in the extreme environment.

First, the apes controlled their diet and adjusted their bodies more strongly to adapt to the current situation of food scarcity as much as possible.

A strange thing happened. Although the apes looked increasingly weak and thin, their thin bodies and extreme malnutrition did not quickly defeat those who survived the first month.

They were still agile, and their lighter weight and smaller size meant that they consumed much less energy when moving.

The changes in adult apes were obvious, but the changes in juvenile and adolescent apes were even more significant.

In order to reduce the energy consumed when moving short distances, these children gradually try to walk upright on two feet only when they go out, relying on the more developed cerebellum to maintain balance.

When upright animals of the same size and weight move the same distance at the same slow speed as quadrupedal animals, as long as the balance of upright animals is well controlled, the total amount of ATP consumed by upright animals is less, and the field of vision is higher, which makes these upright children's efficiency in finding food or wood on the rocks and mountains suddenly improve a lot.

Not only that, the children who should have been protected have gradually learned to swim without any instruction, and their swimming skills are very good. The probability of going out to find food and returning is much higher.

These children have even learned to dive and fish in floods.

During this process, in order to swim faster and more effortlessly in the water, the hair on the surface of the ancient ape child's body began to recede at a very fast speed.

Although the ancient ape child did not quickly and completely turn into a modern human, the hair on the surface of the body became much shorter, and the hair gradually stopped absorbing water. The surface of the hair was quickly covered by the secreted stratum corneum, forming a tiny hydrophobic scale structure, which is more and more similar to the hair and sweat hair of modern people.

Looking at the changes in front of him, Chen Feng was stunned.

It turns out that in ancient times, the changes in human body shape could really be so fast.

There is no need for generations. In the same person, it changes rapidly because of the needs of the external environment.

Chen Feng also realized that the expression of human genes can have such powerful potential.

Scientists have had many different speculations about the evolution of humans.

Even in the later generations when science and technology are highly developed, humans can already use genes to synthesize some new species, and even use colonization technology to turn themselves into new species. However, there are still many disputes and speculations about how humans millions of years ago gradually changed into their final appearance.

Most people agree that the human body shape is the result of slow evolution in constant natural selection.

But in fact, when humans have wisdom and become Homo sapiens, nature's right to choose Homo sapiens has been greatly reduced.

But the process of losing hair on the human body has not ended, but is still advancing.

It can't be because of aesthetic changes that lead to natural selection tendencies when the population reproduces.

Who knows what the aesthetics of ancient humans were like? Maybe the more hair, the more popular they were.

The changes in hair during human evolution have puzzled many paleontologists, and they have come up with various speculations.

Now Chen Feng knows the reason.

In the history of human evolution, there was a period of time when swimming was needed to save the survival of the human race.

Perhaps when this generation survives, the hair will return to its original state due to the need for hunting and keeping warm, but less hair to cope with a more complex environment has been engraved in human memory and will be passed down forever, until one day, when human wisdom reaches a certain level and productivity can solve the need for clothing and warmth, the tendency to reduce hair will be strongly expressed again and eventually become the mainstream.

The rapid evolution of children has given the population a little breathing space, and the food source has been slightly relieved.

But if the rain continues, the population will still not be able to expand and reproduce, and the population will continue to decline due to the deterioration of the external environment, perhaps due to natural deaths or death from disease.

In short, the population will continue to decline, but the rate of decline is much slower than in the first month.

The real change occurred after five months of continuous heavy rain.

Five months of lightning and thunder caused the oxygen and hydrogen on the earth to react rapidly, generating more and more water. The heavy rain caused the water level of the ocean to continue to rise, and eventually formed the surface of the earth.

The persistence of this ancient ape tribe finally reached its limit.

The ancient apes were sick and injured from old to young.

No one could go out to forage for food anymore.

The tribe was truly in dire straits.

It was on this day that a huge biological submarine approached the rock.

In a sense, it could not be considered a submarine because there was no air inside it.

A fish-like person with an upper body similar to that of an ancient ape and a fish tail on the lower body emerged from the submarine and poked her head out of the water.

This was a female fish-like person.

She was very tall, eight meters long.

She forced a smile and waved in a friendly manner, like the ancient apes greeting each other.

Then, a ladder stretched out from the top of the submarine, extending all the way to the entrance of the cave.

The upper part of the huge submarine began to grow buildings that the ancient apes had never imagined, like plants growing.

The submarine turned into a small floating island.

The remaining 87 apes supported each other and walked to the surface of the submarine in confusion and tension.

Here, the apes first came into contact with cooked food - grilled fish. It

was also the first time for the apes to come into contact with medicine.

Chen Feng suddenly knew the source of the fantasy about Noah's Ark in Western mythology, and the origin of the legend of Nüwa repairing the sky and saving the world in the flood in Chinese mythology.

Stacked memories have been hidden in people's hearts through fish food, and eventually turned into myths and legends.

The apes settled down on the floating island, and more than seven months passed.

In the third month, the heavy rain finally stopped, but it was still cloudy, with occasional drizzles, and floods were still raging everywhere outside. It   was not

until more than seven months later that the warm sunshine finally filled the earth again and the ground began to dry up again.

At this time, the ancient apes arrived at the African continent on the Pisces submarine, walked down the floating island, waved goodbye to each other, and began a new reproduction. The picture in front of Chen Feng stopped abruptly.   What he saw was a real history.   Chen Feng fell silent.   This is just one of the many things that the Pisces did for the earthlings.   Perhaps this history is more important, so the Pisces hid it deep in the stacked memory, and after additional encryption, it was finally presented to Chen Feng.   But why must it be this one?   And not something else?   Chen Feng soon found out why the Pisces encrypted it.   It turns out that there is another huge secret hidden in this memory.   During the more than 200 days that the ancient apes lived on the surface of the submarine, they received medical assistance from the fish people and their DNA information was also deeply sequenced.   The DNA information of the ancient apes contains secrets that Chen Feng had never thought of.   It turns out that human evolution had actually stagnated as early as 7 or 8 million years ago.   The subsequent so-called evolution is nothing more than pseudo-evolution of directional feature expression and minor variations caused by the exchange of blood between different ethnic groups scattered around.   The essence of human genes has never changed.
