4.6 Billion Year Symphony of Evolution

In the spring, as usual, the desert was stained with green by the endless explosion of vine ferns. Originally in this new fern forest, there will be a lot of biological tweets, but now ...

It became quiet ...

Not only the desert, but also the twisted jungle. Originally this was the season of reproduction, but there was no fighting sound of creatures, no chirping, nothing, only the smell of rotting corpses, which did not disperse for a long time.

Compared with large arthropods, reptiles only occupy a very small part, they cannot yet be added to this environment, so after this disaster, the entire jungle looks very empty and quiet ...

The large arthropods have disappeared. The present jungle can be said to be a forest of plants and fungi, plus a small amount of reptiles. The number of reptiles should increase suddenly due to the loss of natural enemies, but before , Lin has to wait ...?

There is also an area where Lin ’s Oxygen Fortress is filled with normal sounds, some large creatures are awakening from inside, they seem to have not yet discovered that the world around them has changed. Wake up in a long sleep.

'Boom'.

A scorpion-shaped creature hit the 'wall' on the edge of the oxygen fortress. This creature is one of the descendants of the descendants of the group of desert scorpions that Lin encountered a long time ago, because Lin made the shell transparent It's very high, so it seems that it hasn't been discovered just after waking up, but it has hit several times in a row and found that it was impossible to advance before it bypassed this strange place.

It is not only desert scorpions. In the transparent shell shell, there are often sounds of bumps. Some bee creatures constantly hit the transparent wall. It seems that they are very puzzled why they can't fly through.

This is not surprising, because they have not been trapped in this way, but Lin has found that some creatures even slammed out of the blood, which is not quite appropriate.

Moreover, there are not only sounds inside, but outside, occasionally some boulders will fall down ...

'boom!'

A boulder hit the shell of the oxygen fortress, causing a loud noise that scared away several bee creatures that were hitting the wall.

In the twisted jungle, there is such a huge roar everywhere, the moon is slowly going away.

Through each night, Lin can clearly see that the moon is starting to get smaller and smaller, and the effect on Naruto slowly becomes ineffective.

Lin began to think that Naruto might slowly drop in height without causing great damage, or it would all fall together within a certain period of time, which caused a lot of damage, but that's all.

But in fact the above two are not, but a more strange situation.

After the month began to get smaller, Naruto suddenly lost buoyancy piece by piece ... This is really quite sudden.

Naruto that suddenly lost its buoyancy will fall from high altitude, irregularly and unpredictably. Lin estimated that it may be related to the surface activity of the moon. These boulders falling from the sky occasionally cause a deadly threat, whether it is a creature on the stone or Creatures in the jungle below.

However, Lin has n’t seen Daming Stone Island falling at all. The largest falling stone is no more than ten meters in diameter. If it exceeds it, it will peel off little by little, not the whole one, so at least Will not cause large-scale casualties.

Because of this strange way of losing buoyancy, there are often loud noises in the jungle. Lynn ’s oxygen fortress is not so easily broken because of the special reinforcement of the spider silk, but there are still some cracks on it, Lin needs Use the shell coater to repair, while Lin uses the air force to push away the naruto above.

The headworm also rolled down from the empty boat, just like when it was diving, let the empty boat stop on the water and then roll into the water, but this time it did not roll in the water for too long, but started near the canyon. A new rock mountain was built, ready to live in this neighborhood ...

The mood of headworms is not very good. It is uneasy about this quiet jungle full of carrion smells, because they ca n’t hunt without prey. Although headworms can be planted, they mainly rely on hunting, now Headworms appear to be in a low mood, which may last longer.

Lin made a display to the headworm to see the future evolution of biological speculation, only when seeing this, the headworm will become excited.

But at the same time, it has become more like staying in the rocky mountains, not like to roll out like before.

And Lin is not so boring, Lin let a lot of snowballs float in the jungle, glimpse everything that happened in the forest, and record the changes in the whole jungle ...

In addition to twisted jungles and spreading fungi, some small creatures were found in the forest. They are ... arthropods.

A group of small cockroaches ran quickly in front of Lin, but this not surprising phenomenon suddenly caught Lin's attention.

These cockroaches are descendants of a large arthropod called 'question mark cockroach'. Is this name because of their carapace?'Symbol, but the point is not this. Many arthropods have the habit of holding eggs and overwintering, that is, laying eggs at the end of summer and letting the eggs hatch again after spending the winter underground. Obviously these hatched little cockroaches are nothing Problem, they can live in this environment.

Lin suddenly found that such scenes were everywhere in the jungle, and small arthropods began to appear. They crawled out of the ground heated by the melting snow, and drove in a small body in this world that killed the large arthropods. ...

Arthropods have not yet become extinct. Some species that Lin thought would disappear forever, such as Malu, centipedes, cockroaches, crickets, spiders and other creatures have emerged from the ground. Their newly born small body size requires very little oxygen. , You can live safely.

But what happens afterwards?Will these cubs grow up sooner or later?

Time, gave Lin the answer.

Lin specially selected some fast-growing creatures to observe. A creature called the "golden spider". After more than ten days and nights, these creatures should have grown to more than one meter, but they did not, but they have been maintained. With a size bigger than the cub ...

It turned out that because there was not enough oxygen, their bodies stopped growing, but remained at a young stage, and their reproductive organs also matured and could reproduce directly in this body type.

In this way, does oxygen not cause extinction, but rather reduces their size?
