4.6 Billion Year Symphony of Evolution

The "greening seabed" plan has been extended since Lin decided to start. It covers a large area of ​​the underwater area, and many areas that were originally gray beaches or rocks were stained with a layer of green.

This layer of green is called "green carpet" by Lin, and they spread over all the places where there is light between several bases. In fact, now Lin has no sub-bases, they are all integrated together, forming a huge Base.

Lin doesn't care how long it takes. This behavior will let her get endless energy, but it has a lot of impact on the surrounding environment.

The green carpet usually does not cover some fixed creatures, such as coral or something, Lin will bypass them, but there are also many creatures, especially those who love sand drilling, will be directly covered by Lin.

But they did not disappear, but instead changed a way of life-live directly on Lin ’s green carpet, they made some small cracks in the outermost transparent shell of the green carpet to hide, or directly built on the Own nest.

There are also some leaf-shaped insects that stick to the green carpet with their handles, while the sand-drilling creatures like cut-off shells have completely left the area covered by the green carpet.

Lin started to use troops to drive or kill these creatures living on the green carpet, but after a period of time, Lin did not do so, as long as they did not shade too much, Lin generally ignored it, and some like to take For the creatures in the nest, Lin will let the green carpet cover it directly, but they will not block their nests. Under Lin ’s tolerance, and because the green carpet will release a lot of oxygen, more and more creatures gather on it.

As for some creatures trying to get into the green carpet shell and eat the photosynthetic cells inside, Lin will kill them without hesitation.

This feels very good, in case of any situation, these creatures are also Lin's reserve food.

Covering the green carpet is a long process. Lynn did not travel in this process, but how many years have passed since it was built?

Lin did not record these. During this period, she has been thinking about various issues and conducting some research.

Lin also got some new words, including adjectives of size. Once Lin used one of her arms to compare with it to confirm the size, but now it has an accurate length unit to describe an object.

They are basically mixed with the word '', and usually one kind is ten times the former one, and it will be changed to 'km' when it is a thousand times later, which is very troublesome, but applicable.

For example, generally one hundred thousand cells can form a sphere that can be described as 'millimeters'. A sphere composed of one hundred thousand cells is about one millimeter, but depending on the size and density of the constituent cells, even the same number of cells will have something Very different.

However, the unit of millimeters is already larger than all monomer cells, and even the largest amoeba is only about 70%.

Leviathan's current diameter is about one meter. Among the common creatures here, it is very huge. Among the creatures that Lin has seen, only ice crystal monsters and giant traps exceed this size.

As for Lin's 'green carpet', they may be the largest creatures. The area they cover may have been dozens of kilometers, and Lin did not calculate it.

However, Lin has not yet described the exact size to describe an entire area. It seems that the "diameter" is not suitable, because it should describe a round object.

However, you do n’t have to worry about this kind of small problem ...

Lin did not plan to spread the green carpet further. Lin planned to let Leviathan travel again to see which area is suitable for spreading there, or to put down the seeds of the base there, and then expand the new green carpet.

But recent research has caused Lin to change her plan. Regarding ultraviolet rays, Lin has discovered a great thing.

The land above the water surface belongs to the field of air, and most of this air is not oxygen, but some other strange gas, including a gas that can be used to combine light, most of these gases will not have ultraviolet light What blocking effect.

However, if the oxygen released by the green carpet and other wild photoeating cells is exposed to ultraviolet light for a long period of time, it will become another strange gas and have a blocking effect on the ultraviolet light. The effect is weakened and becomes non-lethal.

But a small amount of oxygen would soon be blown away by other gases, so Lin had an idea, if the amount of oxygen is extremely large, it will be mixed into the entire land?What will change?

It seems a ridiculous idea, because the space outside is so huge, but Lin knows that the released oxygen will not escape, but will always be mixed in other gases, so as long as there is enough time, maybe ...

Therefore, Lin intends to wait. It may sleep for a period of time, just like the oxygen crisis, but this time the motivation is opposite to the previous one. At that time, it was to wait for the oxygen to disappear, but now it is to wait for it to fill the whole world with oxygen.

However, Lin ’s main purpose is still evolution. Most of its evolutionary methods are learning from other creatures, but now he has seen quite a lot of creatures, and those who can promote himself are hardly found. Of course, Lin can go on a trip to see Look at other areas, but Lin still wants to stay here for the time being and observe the biological changes.

Other organisms will also evolve. Lin's research on placing some eyeballs in some flatfish found that the cells in their bodies will combine new structures according to different situations, or add some new functions to the original structure, but these reactions It's quite slow, and Lin's ability to quickly combine new soldiers is completely incomparable ...

But these evolutions are all produced by biological cells. Whether they are brain or brainless creatures, they can think about the surrounding environment, and then respond to their changes and then make changes. Although slow, they are very effective. Usually you can think of It has a perfect corresponding plan, but the ability to deal with mutations is quite poor.

Lin's cells also have this ability, but Lin prefers to directly synthesize or learn other creatures.

The brains of other creatures seem to be only responsible for allowing organisms to respond quickly to the environment, but they do not include the control of their own evolution, so the evolutionary response is still quite slow.

Under this slow change, the individuals will become different, but some creatures have a special method of 'combination'. The cells released by two different flat fish are combined, and the cells divide and grow into new ones. The new flatfish may inherit the advantages of the first two flatfish, and sometimes even appear to have new and powerful capabilities.

This seems to be called 'sexual reproduction', and it feels very interesting. Some other creatures, such as jellyfish, use a very similar split method, so the new individual can only inherit the advantages of one individual, unlike the flat Fish can inherit the advantages of two individuals.

However, Lin believes that her evolution is stronger because it does not require the exchange of information between cells.

For example, Lin ’s cells in an area have some kind of evolution, and they can immediately use their thoughts to make all the cells evolve accordingly, no matter how far away they are, without contact.

Lin ’s thoughts seem to have an effect on cell evolution, but the effect is not complete. It seems that the most basic thing is to get the corresponding information. Lin must understand that evolution, which is of great help to the evolution of its own cells. Lin first learned The principle of photosynthesis, so cells can quickly combine light-absorbing substances. If cells are allowed to combine themselves, I am afraid that there will be no response for millions of years.

In short, there are many complicated secrets.

So Lin not only intends to silence for a while to fill the land with oxygen, but also wants to observe the evolution of other creatures, and finally understand the secret of evolution ...

How many years does this take?

Maybe a long time ...

In order not to be bored, Lin will enter a state similar to a deep sleep, but its troops and eyeballs will continue to work, recording all the changes in the surroundings. When they change greatly, Lin will wake up.

Or what happened around him, such as a tsunami, fault, or lava, etc., Lin will also wake up, but Lin thinks that it already has such a huge area, these things will not have a great impact on it.

At the main base on land, Lin has surrounded it with a carapace, and she will continue to test the air environment until she is not so strong when UV is not strong.

The presence of the green carpet allows Lin to never worry about food unless the world loses its day.

Now, wait for the world to change ...

What do you see when you wake up again?

Because green carpets cover large beaches or rocks, many creatures have lost the gravel they originally hid. When they find themselves exposed to danger, they will need faster speed and stronger power, which can stimulate their evolution.

Most organisms now feed on single cells floating in the water, but slowly they start to increase in size and cannot satisfy single cells, so they have more powerful power and focus on other multi-celled organisms.

And the preyed creatures also grow harder crusts and body shapes. This relationship allows them to grow in competition with each other. Coupled with various environmental factors such as cold and heat, the future creatures will definitely be very different.

In the end, what will happen?

Until Lin wakes up, she won't know ........................................................................ Thanks to Shengyangyu ~ 1888 ~ Thanks ~ Soul Seeker ~ Big I'm like ~ I want to think, I want to think ~ The reward ~ PS: There will be more and more after the 13th ~
