4.6 Billion Year Symphony of Evolution

This is the 'army' made by Lynn. Each of them is ten centimeters long. Its body is mainly bullet-shaped. It can use the last pair of articulations to spray water, and the second pair of articulations is a flat auxiliary movement. The first Due to the attack on the arthropods, most of them are blade-shaped, and some are spout-shaped, which are used to launch explosive shells.

There are thousands of this 'army'. They were digging holes in some large crystals before Lin fell asleep and began manufacturing, but the manufacturing stopped after a certain amount. They are mainly used to explore this new world. At the same time, hunt and decompose interesting things.

The bullet-shaped structures swim quite fast in the water. They swim in one direction at the fastest speed. The surface of the crystal land has been covered with ice. It has never changed in these years. In the cold and dark waters, The warhead lantern found a lot of wonderful creatures floating here.

These creatures with round shells and heads with tentacles are called 'chrysanthemums', which are similar to arrow stones, except that the cone-shaped shells are rolled up, and the size is only about half a meter. The shell is not suitable for a warhead attack, and Lin does n’t think that there is any place in Ammonite that is worth learning ... But the interesting thing is that Lin does not know what evolved from Ammonite, maybe it is some kind of snail?There is no relevant information in the observation memory of the eye.

There are quite a lot of ammonites, and they are distributed in large parts of the water. The warheads swim along this huge group of ammonites. They quickly left the darkness and came to the area illuminated by the daylight.

This was originally a beach with giant traps, but this strange monster with body traps disappeared a long time ago. Although Lin did not cover their 'trap hole' when covering the green carpet, these monsters' After all, the body shape is not suitable here. In the memory of the eyeballs, the last giant trap seems to be frozen to death by icicles. The icicles with super high freezing ability will occasionally appear. Lin still ca n’t explain why. ,

Now, it is covered by a piece of green, but it is not Lin's green carpet ...

This piece of green is dancing on the seabed like tentacles. They are the evolution of those wild light-eating cells. They stick to the green carpet of Lin with their roots, and they multiply and divide in large numbers, completely covering the original cover of the green carpet. Area.

Lin's green carpet also has a setting. If you can't receive light for a long time, it will decompose and digest itself, so this area has been completely occupied by this group of green cell evolution called 'seaweed'.

Lin did not think it mattered, because the nutrients obtained by eating seaweed directly are much more efficient than the green carpet to slowly synthesize light energy. Then the seaweed will be completely cut off, but now the warheads are not responsible for doing this, Lin is more interested in some creatures in the seaweed group.

The warheads swam above this seaweed jungle. Lin found some huge creatures wandering among the seaweed clusters. They were about two meters in size. They twisted their thick and streamlined bodies to chase those smaller creatures in the water.

"Shark", Lin's new word can describe this creature that evolved from the flatfish. The flatfish used to be rare and small, but now it has evolved quite a lot of different kinds of creatures.

This is a peculiar thing. Lin generally thinks that the same creatures will evolve differently only if they are far apart, but it seems that this is not the case, and creatures in the same area may also grow differently.

Why is this?Lin didn't care so much.

A shark is chasing another fish in the seaweed colony. This fish is more than half a meter long. There are a pair of thick fins on both sides of the body, so it is called 'meat fin fish'. This is a shark. The chasing finfish quickly rushed out of the seaweed group and quickly escaped towards the surface of the water.

The shark is a creature that evolved for hunting. Its head has a large mouth full of teeth. Its flat fin is more suitable for high-speed swimming. It catches up with the finfish at a very fast speed. A large piece of meat was torn off his mouth instantly.

Other sharks feel that their companions have successfully hunted, and they have gathered around to plan to share. In the evolution of the past, these creatures have become more and more aware. Even if there is no fluctuation in the water, some creatures can still do it without eyes. Knowing the exact location of the target, Lynn knew it was an ability called "smell", but what exactly is smell?Lin is not yet clear, this must be studied.

However, the shark's vision is also very good, but Lynn learned from the observation of the eyeball that the shark's sense of smell should be the best among all living things.

The evolution of the eye is also reflected in some organisms. Lynn found that the eyes of ordinary single-celled organisms can only feel the light, and they cannot analyze complex images. Until the appearance of multicellular organisms, the eyes of many organisms are still the same. Creatures that can analyze the eyes of complex images.

Well, Lynn used to have no vision, but the piece of crystal-like object that the observer ate made it gain vision. Even after that, the cells would imitate the crystal structure to form an eyeball.

What exactly is that crystal?This is still an unsolved mystery, and all the crystals that Lin has discovered so far are different ...

Think about this later, you should find this kind of "visual crystallization" sooner or later.

Now, the shark swarm quickly divides the finfish, and then they spread out again. Unlike the flat fish that like to be mixed together, these sharks have slowly alienated their kind in evolution ...

After they dispersed, the warheads swam towards the nearest shark. These sharks didn't take the ten centimeter warheads seriously, but they were wrong.

It was too late when the shark found itself surrounded. The warheads swarmed up. They cut the shark's skin with sharp forelimbs.And some are besieging the softer gills of sharks.

The shark did not want to fight back at all. Instead, he twisted his body frantically and tried to escape to the distance. It rushed out of the seaweed colony at an extremely fast speed and escaped towards the surface of the water.

The warhead swarm followed, and the shark's wound kept pouring out a lot of cells, which attracted its fellows, but these fellows did not come to help it, but wanted to share their companions.

They have become too individualized and even devour their companions. Lin has never understood how the shark has evolved such a wonderful form of survival ...

Lin divided a part of the warhead to chase the shark that was chasing, and the remaining hundreds were still chasing the escapers, until they were forced to the water by a huge floating ice, it had lost its retreat.

However, without waiting for the warheads to start, the huge ice floe next to the shark suddenly cracked, and a barbed sickle protruded from it to catch the shark.

this is……

At this time, the huge floating ice slowly cracked, under the cracked ice, there appeared a glittering figure covering the whole body of the crystal armor.

This organism is more than five meters long. Lin is very familiar with this creature because it is the evolution of the ice crystal monster ...

Lin initially did not understand the life habits of the ice crystal monster, but in all-year observation, Lin found that the mature ice crystal monster would return to the crystallization place to breed, while the small ice crystal monster would grow up to a certain extent before leaving there.

The appearance of the ice crystal monster has changed very little, only the body size has increased, and the whole body is still covered with crystalline armor. Its forelimbs are specialized into barbed scythes, and the head has two huge eyeballs. There is no doubt that this creature has a The ability to kill sharks in seconds.

In this era of hunting, Lin found that the more leisurely way of activity was no longer applicable. It should have completely surrounded the shark just now, so that it would not be robbed.

Now the warheads may not be able to harm the ice crystal monster, so they must dispatch the 'Ace' who has been sleeping with Lin ...

The ice crystal monster's mouth is a rift covered with blades and serrated pliers. It can easily tear the shark, but even if it covers the crystal armor, the huge ice crystal monster also has enemies. A huge creature slowly swims from a distance to see It was attracted by the shark's body ...

Its ancestor was flatfish, but it evolved from flatfish to helmetfish, and then evolved from helmetfish. It is also the largest creature in Lynn ’s memory to date.

At ten meters long, this giant fish's head is covered with strong armor, but unlike the useless and troublesome head armor of the helmet fish, it has huge blade-shaped teeth at the end of its head armor, and it divides the head armor into upper and lower. Both ends, so you can open and close the prey.

It rushed directly to the ice crystal monster, and bit the carapace on the side of the ice crystal monster's body tightly. Just twisting his head, he easily torn off a large piece of cracked crystal armor.

It has strong pressure, and can even crush the ice crystal monster's armor. The ice crystal monster dropped the shark, and the powerful water spray device of the hind limb quickly escaped.

Although the giant fish has strong power, but its speed is not at all, it has to give up the ice crystal monster and eat the little shark.

What a fun environment ...

Lin found that it was almost watching the show from beginning to end, but there are still a lot of gains, so the next step is to be more serious and let it appear to recover all the interesting things!
