4.6 Billion Year Symphony of Evolution

This is the fifth type of multicellular organism ...

Leviathan is now in a cave under the Island of Ashes. Lynn found that there are many creatures on the surface of the relatively moon. Leviathan is now looking at a creature in front of him and observing and recording it.

This creature is called the 'gray mushroom', which is a sponge-like, very soft and highly toxic creature.

This thing is more than one meter high, and its overall shape is cylindrical. It stands on the ground like a mushroom. There are no organs in the body. Lin found that her only food is the dust floating in the surrounding air. Its body has many small holes through it. The cells move to absorb the water and food in the surrounding air, and some are like primitive filter-feeding organisms.

At present, this is the largest multi-celled creature that Lin has seen except for the 'grit monster' I saw before, but the structure is very simple, and the others are very small in size, living with those fungi in the water pool.

In fact, the gravel monster can not be considered as 'big', after all, it is a polymer of many small gravel.

Although the composition of these creatures is the same, the structure and the creatures on the "pompom" are very different. Lin found that they do not use oxygen, because there is almost no here, but another method is used instead of oxygen.

It may be another gas in the month, or something else. At present, the structure of their body has not been fully studied, and their circulatory system is also very different. It is a very basic structure, but uses some special cell extrusion to transfer energy.

I don't know if this is the case for all living things, or if it's the kind of creatures found so far.

Now, Lin is mainly looking for some big creatures, and there will definitely be here, because ...

'Boom ...' Thinking of this, Leviathan heard a rumble from outside, and the Island of Ashes was ready to erupt again.

'Boom!'With the noise, Leviathan suddenly felt a strong suction. I saw a huge amount of dust pouring in from the entrance of the cave, just like a sandstorm. It swept through the cave. After the storm of dust passed, the ground and the water hole There is still a lot of dust in the middle, and Leviathan is covered with a thin layer ...

More dust poured into the depths of the cave, there seemed to be something ... sucking the dust.

The dust was originally sprayed straight from the bottom to the surface of the island, and here as a cave on the rock wall, it is unlikely that any dust will enter. At most, it gathers at the entrance of the cave ...

However, these dusts are the main source of life for the creatures here, because they are mixed with many decomposable foods, and the fungi and other creatures in the water pool need to decompose these dusts.

And when Lin was thinking about how they got the dust, this phenomenon appeared ...

When the dust swells, a strong attraction also occurs at the same time. It sucks the spitting dust into the cave, and it will last for a while, so that the dust reaches the depth of the cave.

The dust that is spread is basically decomposed by those fungi, and then larger organisms eat those fungi, so that they slowly grow up layer by layer, and finally reach large organisms.

if so.

Now, Leviathan is uncovering what makes this attractive.

In the flying cave of Leviathan, the sound of water droplets sounded everywhere. There were often drops of water on the top of the cave, and then gathered into a pool of puddles on the ground.

This seems to have created the environment in which they live. The water may come from the sea, but the material inside is not so complicated, and it looks more 'pure'.

Suddenly, Lin discovered that Leviathan's light had irradiated a moving object. He drank beside the puddle, and even if it was exposed to light, there was no reaction at all.

This creature looks like a cylindrical stone over a meter long, covered with very thick needles. It is now leaning on the side. Lin saw that the ends of the needles on the side of his body opened a small hole. , And sticking out something like a tongue from inside, licking the water in the puddle constantly.

This is what the sixth multicellular organism looks like.

It looks ... it doesn't seem so strange.

Leviathan was about to take a closer look. The creature suddenly felt like it was. It retracted all of its "tongue" and then rolled away on the ground at a very fast speed.

This is obviously a creature that is good at tumbling, but Leviathan catches up at a faster speed and reaches out his tentacles to grab the cylinder that is constantly rolling on the ground.

At the moment of grasping it, it suddenly ejected a large amount of liquid from the acupuncture on his body.

This liquid seems to be highly toxic to their creatures, but it's nothing to the 'pompon' creatures.

After Leviathan put miniature arms on this creature for research, Lin found that it seemed to be a similar species of grit monsters. Although this is not an aggregate, its shell structure is the same as the grit monster's grit, and The shape inside it is also like a gravel.

But it grows so big, like all creatures here, it has no eyes.

Wait ... Is this ...

During the exploration, Lin's miniature soldiers found a place storing a lot of fat at the end of its body. This seems to be the storage area, but Lin found that there were many white substances in the stored things.

That's right, this is ... white paste!

Thinking, Lin immediately put down the creature, and Leviathan quickly flew deep into the cave.

There are puddles everywhere. Leviathan investigates every puddle at the fastest speed and searches for microorganisms inside. So far, Leviathan has found dozens of fungi, but No one is familiar to Lin.

Suddenly, Leviathan stopped.

Because there is another creature in front, this creature is only thirty centimeters high, it looks like a plant called "radish", but this "radish" is standing upside down, with three slender legs on the ground go.

Sure enough, the creatures here are wonderful.

However, Leviathan mainly pays attention to the location of these "radishes". There is a pool, and that pool is different from others. Although it is also very turbid, the color inside is mainly white.

Leviathan flew there immediately, the 'radish' was suddenly scared away, Leviathan flew into the pool and immediately reached into the tentacles and tested the ingredients inside.

Sure enough ... there is white paste inside.

The fungus that lives in this puddle is one that Lin has seen. It can be named 'white paste fungus', that is, those fungi brought by the creator. They seem to be decomposing dust and making white paste.

However, the white paste made by these bacteria is not the same as Lin's previous understanding. Lyn tried to decompose this white paste and found that there is a toxin in the white paste, whether it is on the moon creatures or on the pompon Creatures have effects.

This toxin is relatively basic and can damage the synthetic system of cells, but it has no effect on themselves.

This is also a matter of course, because the reason why they make white paste seems to be used for storage, not to be eaten by other creatures ... Although, there should be some creatures here to eat them, just like the radish just now I was about to eat them, and the cylindrical creature I saw before seemed to be able to eat white paste.

They seem to have nothing to do with the creator, but a separate fungus.

However, the creator may have used their ability to make white paste, and finally let them make a non-toxic white paste, which is then used to feed the sword fleas in their bodies.

But what about the process in between?

This is difficult to investigate. I do n’t know how the creator arrived on the pompon. Maybe it was relatively primitive at first, and then slowly evolved into that look ...

Now, Leviathan continued to move forward, as if approaching the bottom of the cave.

Under the light of Leviathan, more creatures appeared here. In addition to the previous radishes, Lin also saw some creatures like stones, most of them only a few centimeters, relying on extremely slow peristalsis Way to crawl on the ground ...

Not only the ground, but Lin also saw wonderful things at the top of the cave. It seemed that soft silk threads were spread all over the top of the cave, reflecting the shining light under the illumination of Leviathan.

These creatures are called "Lipules" by Lin, and those structures that appear to be silk threads are actually aggregates of fungi. They seem to get this shape specifically for dust, and they can also directly get the water from the top of the cave.

The most living thing here is the radish, because I did n’t expect a good name, so I called it radish directly.

They run very fast and eat white paste in the surrounding puddles, but they do n’t eat much. Lin estimates that they need to wait for the body to remove toxins before they can continue to eat.

Lin saw a radish running on a pool of gravel. The beach suddenly moved and wrapped the whole radish in ...

Sure enough, the gravel monster preyed on this disguise. It seemed that it didn't eat the things in the puddle, but lived entirely on prey.

Leviathan made some observations here. In addition to the previous ones, Lin also discovered some stone-like creatures. They move very slowly, and they all rely on fungi in the puddle ...

The creatures here are really rich. Although there are not many kinds of creatures compared to the frozen pom-poms, Lin thinks there are more kinds of creatures here, and some of them are quite huge.

Leviathan has stopped at a place now. It seems to have come to an end. In front of Leviathan is a wall, and on the wall, there are many ... cracks.

This is where the dust is sucked.
