Scientists on Earth have always wondered where humans came from.

How did the great variety of life on Earth come about?

What was the Cambrian species explosion all about?

Why did human evolution be so different from other life?

……

There are too many doubts.

It's just a pity that no one can answer.

But after Xi Tong saw the actions of the new humans in the nuclear leveling world, he vaguely caught clues.

Because the organic matter created by the new humans is expanding, spreading, and uncontrollable at a rate visible to the naked eye.

When the new humans synthesize these organisms, they implant an instinct to copy, copy, copy......

With enough energy and enough matter, they can naturally synthesize and copy themselves without stopping, constantly changing one into two.

At the beginning, the base was not large, and the expansion speed was not obvious, after all, the doubling of a hundred was only two hundred, and those subtle substances gathered together were the size of a needle tip.

However, when the base reaches 100,000,000 or even exceeds 100 million, the increase in quantity brought by each copy is different.

Xi Tong began to feel that the essence of life lies in continuous reproduction, and it is the countless repetitive individuals that make up wonderful lives, and even wonderful universes.

The single lattice of the hive may not be beautiful, but the countless hexagonal lattices are densely arranged together, which has an indescribable special beauty.

Looking at the ancient art treasures, whether porcelain, wood carving, printing and dyeing or bronze, there are constantly repeating patterns or patterns.

This is not art, there is no slightest agility, but this monotonous and boring repetitive patterns and patterns full of ingenuity interpret the origin of life.

Repeat.

Keep repeating.

Copy.

Keep copying.

An area of the nuclear flat world is covered and filled with organic matter, wrapping the peaks, filling the rivers, and obscuring everything.

As soon as the invincible giant beast was contaminated, it let out a heart-rending howl, and even the mutated giant beast was wrapped in an ocean of organic matter, like a mud cow entering the sea, and it could not exert any strength in the air.

And instead of fear and worry, the initiator looked happy and triumphant.

He didn't know what the consequences would be if this kind of thing got out of hand.

Maybe it's because of the different experiences on the path of expansion, or maybe it's a particular variable, but in short, when these organic matter expands to thousands of kilometers, different individuals appear.

They are no longer unified.

Organic matter that expands to the north and organic matter that expands to the south becomes two very different things.

Variation.

It's not good, it's not bad.

After all, there is no practical proof, and no one knows what their efficacy and effect are.

Only the producer of organic matter was excited, as if he had solved some world-class problem.

Thus, while the two organic matter continued to expand forward, they attacked each other at the point of contact, destroying the dissidents.

In the process of advancing, the organic matter once again split into different camps.

This time, Xi Tong saw it clearly.

The reason for their split is the difference in the moisture, temperature, minerals, and powerful behemoths they devour along the way.

This subtle gap has become the trigger and fuse for their mutation.

The amount of organic matter released by the new humans is innumerable, and there are many species that have survived and spread out, and there are even more divisions and mutations in the middle, which is impossible to count.

The battle between organic matter also quickly changed from catching and killing to a three-country melee, and even a big brawl.

No one knows what will happen when they collide with each other, like a pair of chemical agents mixed together, and the devil knows if it will bubble or explode in the next second.

Two different organic matter, maybe you devour me, or I devour you, or both are taken advantage of by other organic matter, or the two are intimately combined......

In short, Xi Tong has seen changes from low to high, from simple to complex.

Most importantly, this change happens very quickly.

From the release of organic matter to the birth of the prototype of life, it takes only seven days.

Seven days?

Why is it seven days again?

The new humans in the nuclear world were very interested in this kind of newborn life, so they collected it vigorously, and then gave it their own inventions or utopian life formulas.

These life specimens are like blank pieces of paper on which you can scribble and scribble.

Just as humans use mice for experiments, new humans also use those life samples for research.

The way they do it is to keep giving life to formulas, occasionally adding something new or cutting something that they find complex.

As for whether these life samples will survive, what will they live like......

Let it be.

The hearts of the new humans are big.

If they have watched science fiction movies, horror movies, and disaster movies, they will understand that deoxyribonucleic acid is something that cannot be thrown around.

Even if it doesn't hit people, even if it hits flowers and plants, it will have unpredictable consequences.

A new life was born.

Hundreds of millions of insects and plants appeared, and then gradually gave birth to reptiles, birds, mammals, fish, ......

In addition to the evolution of life samples, there are also products of life samples combined with other surviving beings.

In the previous nuclear leveling world, although many strong people were killed, their bodies were unexpectedly preserved, and then they were also eroded and dissolved by organic matter or life samples, and then different changes were born.

In short, the demons are dancing.

Countless species are born every minute, and the rate of this birth advances to every second as time goes on.

The birth rate of species in the nuclear flat world is unbelievably fast, and at the same time, the speed at which species wither is also fast to the limit.

Originally, after the peace, the whole world was reshuffled, 99.99% of the living beings were lost, and the surviving living beings possessed everything, and the resources could be shown to be endless.

However, after a few months, the whole world was occupied by new life, and the vast and empty world was filled with it again.

At the same time, many powerful outliers have spawned in the new life. And these outliers, without exception, have become chieftain-level figures.

With insufficient resources to support such a large ethnic group, disputes and anchors became more and more acute, and war inevitably broke out.

New humans have joined in.

Not to administer justice, but to gather resources and summarize the formula of life.

All life in this world is their test subject, and they are naturally honored to see the test product thrive.

At the same time, they can't wait to kill those excellent leaders and squeeze the value of the test products.

After all, this is an opportunity for the whole race to evolve, and once the formula is successfully verified, not only can the evolution speed of the whole race be promoted, but also a large number of points can be obtained to improve their authority in the city.
