4.6 Billion Year Symphony of Evolution

Who threw this wooden thorn?

Even if the neck was pierced, Lin's pterosaurs turned around and looked around like normal. Generally, dinosaurs will use the neck as the trachea, but Lin is used to breathing with body-side stomata structures similar to arthropods. There is a sac underneath, which achieves the effect of the lungs, even in a hypoxic environment.

But the wonderful thing is that Lin didn't see the creature throwing the wood thorn. The previous Skeletal Dragons had long gone, and there were no creatures around ...

Forget it, let's save this skeletal dragon named Tucker first, otherwise it will die.

Pterosaur used his mouth to pull out the wooden thorn stuck on Tucker's chest. Before the blood flowed out, he immediately spit a lot of viscous liquid on it. This liquid can stop the bleeding and help repair the wound.

At the same time, Lin also had to see if the internal organs were damaged, so there were some micro-arms mixed in the mucus and observed in the wound.

"Goo ..." Tucker groaned low. Normal creatures will feel "comfortable" in their brains when the wound recovers, and this time it has not fainted, so it is still looking at Lynn in surprise Pterosaur.

Lin didn't plan to ignore it before it recovered. Lin also had to pay attention to the little creature that she caught before. Its length was only more than one centimeter, but it was covered with fluff and tail.

Lin's current pterosaurs have swallowed it into her belly and disintegrated ... and this creature is really strange.

It is not like reptiles. In fact, reptiles or dinosaurs do not have this kind of fluff at all.

In addition, this organism has a structure to maintain its own body temperature, and this dinosaur and some reptiles also have it, but Lynn found that there is a special structure that bulges under their abdomen. Used to feed cubs.

This seems to be the structure called 'breast', which feels pretty good.

Lin also found that their reproductive structure is not the same. This species does not seem to lay eggs, but instead let the reproductive cells start to grow slowly into a pup directly in a hollow position in the body. Cub.

In this way, the mother can provide very good protection for the pups. They may be a new type of group. Dinosaurs may be new, but in general they are similar to reptiles, but this creature is very different. , May have evolved from a creature like the twisted jungle spar.

The spar lizard allows eggs to hatch in the body, and this creature directly grows the pups in the body, and the mother provides nutrients. It is an obvious type of evolution. Their heart beats very fast. Lynn estimates that this creature needs to exceed Only a high frequency of eating can live. They may feed on the roots of plants and some small arthropods.

But they are too small, why should they grow so small?Is it because the dinosaurs around are too big?So Lin should give this creature a name ...

It's called 'Mao Yu'.

Is there any complex meaning in it?Probably represents a small, funny creature

After decomposing this creature, Lin used the pterosaur's neck muscles to slowly squeeze out the wooden thorn inserted in the neck. This wooden thorn is very thin and does not hurt much, but it is accurately punctured on the trachea. Although the piercer did not expect that this pterosaur had no trachea.

Now Tucker has recovered slowly, and the wooden thorn did not hurt its internal organs. It climbed from the ground and first touched the wound on his chest. After confirming that there was no problem, it began to continue to use amazing emotions. Looked at Lin's pterosaurs.

A pterosaur, pulled out the wood thorn and saved it, is this a difficult thing for Tucker to imagine?It and its ethnic group may have never encountered such a thing, in fact, they should never have seen the scales of pterosaurs.

The brain received too much information at a time, which made Tucker's brain a little unbearable. Lin speculated that the skeleton's brain should be bigger than the ancient squid. They used items longer than the ancient squid, and the brain gained more Evolution.

Lin also looked at it at the same time, but did nothing.

After looking at each other for a while, Tucker suddenly lowered his body, grabbed a few stones from the ground, and placed them in front of Lynn's pterosaurs. Then he put these stones in a triangular shape.

What is it doing?

Tucker raised his forelegs and swayed, and began to jump on the ground with his legs.

It seems to be doing a movement called dancing. This Lin also heard headworms saying that they would do similar things, mainly because when they were very happy, their body would start to swing.

Was it happy because it recovered?

"Dancing, learning, can be used to celebrate and get barbecue." At this time, the head worm in front of the display is also teaching the dragon to shake the body.

Tucker stopped after jumping for dozens of seconds, then he found a flat stone on the ground, and then placed the flat stone in the triangle that it laid out before it, and then it He took out a sharp stone and carved a few traces on the flat stone.

It looks like a triangle, and then draws something like an eyeball in the middle.

Lin does n’t know what it means to do these things, so you should start quickly, right? Maybe this creature likes to do these strange things before it causes its head to grow?Or is it just after the brain gets bigger that we start doing these strange moves?

Lin is also studying what causes their brains to develop faster than common organisms. Among a large number of species, only a relatively small number of species will have this kind of brain evolution, but they are usually the focus of all creatures. , So it ’s easy to find.

Curiously, arthropods usually only have divisional species with high intelligence, while other organisms have not seen divisional species, and their individual individuals will slowly evolve their brains.

After drawing the pattern, it seems that Tucker finally finished it, and it picked up some useful stones on the ground and continued the journey ...

Now, the previous Skeleton group seems to have gone a long way. Although it took a lot of time for Tuck to recover, it also took a lot of time to do those strange actions. Now it may not be easy to catch up with them.

Tuck was not nervous at all. He grabbed a handful of dirt on the ground and smelled it carefully. Then he immediately knew the direction, and then he walked south.

When he left, he always looked back to see if Lin's pterosaurs had followed up, as if it were very concerned about Lin now.

This is obviously a matter of course. After all, Lin has resurrected it twice. Generally, creatures like to establish symbiotic relationships with species that are helpful to themselves. For higher-intelligence creatures, this relationship is achieved particularly quickly.

"Woo ..."

There was a cry from the wasteland ahead, and Tucker immediately hid behind a stone, while the pterosaurs flew up high, and Tucker leaned out and looked forward.

That is a creature called 'turtle'.

This creature looks like a lot of fun, it seems to be learning arthropods, and the carapace has grown beyond the body surface, but Lin can clearly see that they are evolved from some kind of reptile. Lin has seen similar species in the sea. This kind of creature ignores the speed for defense, but Lin feels that if they don't grow a shell, there are no creatures to eat and hunt them.

This turtle should be called a giant tortoise. Each head is about 9 meters in length, and may weigh more than ten tons. The shell looks very heavy, and the long neck is four meters high. They move every time. , Will make the ground tremble.

These large creatures were moving south, and Tucker seemed very excited to see them. It rushed out immediately, and it used its claws to hook up the crack of the carapace on the side of the giant turtle. The giant turtle ignored it, but Moving on ...

Maybe he did n’t think of it as a threat at all. After Tucker got up, he yelled at Lin in the sky. In this case, Lin also flew down, and landed on the top of the giant turtle that Tucker took. .

These tortoises are also regarded as buses in the desert. Although they walk slowly, they are very labor-saving.

The giant tortoise swarm slowly. On the way, Lin found that many of the carnivorous creatures would see the giant tortoise, and even the tyrant lizard flinched. It seems that even this large monster does not want to mess with These turtles.

Giant tortoises will deliberately step on trap plants like cruel piercings. When they are put together, those spikes will not damage the giant tortoise at all, and then the giant tortoise will eat these plants in turn.

Tucker had always been very relaxed on the invincible bus. Time passed slowly. When approaching the night, the giant turtle finally reached the place it wanted to go.

This place is like the dividing line of the earth, on one side is a wilderness full of low plants, on the other side is a completely deserted white desert, the sand seems to be mixed with salt, dry hot wind swept the surface, in this white sand sea , Lin can't see any creatures.

Tucker jumped off the giant tortoise. The giant tortoises did not stop. They continued to walk in the direction of the white sand sea, not knowing where they were going.

Tucker's goal is a pile of things on the edge of the sand sea ... what is called a shack.

'Shack', Lin feels a very weird word. Those things look like a pile of wood in a circle, and there are dozens of them on the edge of the sand sea. They are all surrounded together. This should be a dragon. The built lair.

Why are they building nests next to this dry wasteland?

Under the shack, there are some skeletal dragons running around. They are all very small and look like a group of cubs.

Tuck walked towards the cubs, and it shouted at them while walking. The cubs were terrified when they saw it. They were full of fear and fled into the hut all at once ...
