The evolution of insect swarms from XNUMX million years ago

Chapter 119 Login again

The remaining Horseshoe Crabs still don't know why their kind died. They are still swinging their sharp flat tail blades and killing the common workers on the mother farm and beside them.

But at this time, a large number of ordinary micronized torpedoes had already poured out from the opening of the Gana cabin on the side of the pioneering mother. They were swinging their paddling feet and running their water jet propulsion systems to kill several horseshoe crabs.

This is a situation where the Straw Horn Stone Nest Group once had to retreat and had to develop a grade of Youxu Horn Stone to deal with it. How could these Horseshoe Crabs be able to cope with it?

The tail blade of the Horseshoe Crab is one of the few gene sequences of the Horseshoe Crab that Lin Yi wanted to absorb since entering the Silurian Period.

The previously encountered Xiushan horseshoe crabs and their close relatives, the mixed sea horseshoe crabs, and the soldiers developed from the feather-winged horseshoe crab template have no advantages compared to the Anji ancient horseshoe crabs and other invisible horseshoe crabs, except for their ability to survive. To survive, he is confident that he can survive even better than the invisible horseshoe crab.

Although with his current gene editing ability, it is not difficult to create a structure similar to the tail blade of horseshoe crab, but if it can be solved by copying, ah, no, convergent evolution, why bother to grow it yourself.

The swarm of micron torpedoes swarmed out and quickly killed several horseshoe crabs. The huge body of the pioneer mother also swung its paddling feet, slowly stepped forward, and used the three pairs of small claws next to its mouth. He clamped the body of a horseshoe crab and started to eat.

This time, there was no floating mother nest accompanying the team, and for the time being, Lin Yi did not plan to let individual pupae turn into new mother nests, but directly let the pioneering mothers eat.

Yes, during the long end-Ordovician mass extinction, Lin Yi finally completed the reverse integration of the brood gene sequence and realized the de-brooding of gene editing and absorption.

Now, this system has been integrated by Lin Yi into the genetic sequence of the pioneer mother that has been upgraded again, large and small, making the pioneer mother a true mobile mother nest in a sense.

Although the gene sequence still cannot be shared in real time, this undoubtedly increases the flexibility of gene sequence extraction and editing, allowing Lin Yi to no longer need to go all the way to produce the mother nest.

Several horseshoe crabs attracted by the stickleback group were all killed, and there were no obstacles in front of the migrating stickleback group. They swam into the lake in groups and began to lay eggs.

And Lin Yi didn't bother to care about them. As for how these sticklebacks reproduced, and whether they would die after spawning like the migratory fish of later generations, Lin Yi didn't care. He came to this fresh water with a more important mission.

Five pairs of flat paddle-like paddling feet flap, driving the huge body of the pioneer mother to cruise in the lake, and a pair of well-developed compound eyes scan the surrounding environment.

In addition to the sticklebacks that came from afar, there were a large number of strange fish with jaws and no jaws swinging their tails, which seemed like they were all swimming in the air. There were also a large number of bottom-dwelling fish on the sand at the bottom of the lake. Small horseshoe crabs were looking for food in the sand, and Lin Yi even saw a few freshwater trilobites.

This lake has a good environment and a complete ecosystem inside. It is very suitable as a springboard to help Lin Yi make the leap from ocean to land.

Yes, this time he followed the migrating stickleback group into fresh water, just to find a suitable foothold and prepare to complete the mission he had planned before the mass extinction - to land on land.

In the early Silurian period, primitive vascular plants had appeared and landed on land, and together with the same primitive mosses and lichens, they dyed the barren land with a touch of green.

As for whether land animals appeared, Lin Yi didn't know. Later fossil records of completely terrestrial arthropods can be traced back to the late Silurian or even the early Devonian, but this was not important to him.

The pioneering female frog slowly lays a special egg, which is picked up by several workers and slowly moved to the water near the shore - the egg is regarded as the mother's nest. The mother nest also has the function of adapting to the osmotic pressure balance of both seawater and fresh water, and there is no pressure when established in fresh water. It soon began to multiply and gradually formed the first holes.

The body of the pioneer mother slowly sinks, extending the hose structure connected to the core supply bag, and connects with the holes on the surface of the new mother's nest to start transporting nutrients.

The breeding rate of the mother nest is very fast, and the sea ringo - it seems that it is more appropriate to call it river ringo now - clusters begin to spread, and the body also begins to grow rapidly in size. Soon, the holes on its body surface are enough to produce workers.

But this time, Lin Yi didn't need the mother's nest to produce ordinary workers - from the holes on the surface of the mother's nest, the figure slowly crawled out, breaking through the pupa skin on its body, revealing two pairs of chelicerae and five pairs of thick legs. .

Exploration Engineering, a grade that Lin Yi had produced as early as the Ordovician, was now produced by him again with the further improvement of the 2 terrestrial ecosystem.

Five pairs of weight-bearing feet move staggeredly, pushing the body along the shallows and climbing up the lake shore. The water droplets on the body slide down the exoskeleton and drip on the original "grass" ground composed of lichens and low vascular plants.

A million years later, the Hao tribe set foot on land again - if Lin Yi was not controlling the entire hive as a hive mind consciousness, but was like the existence of human civilization in later generations, perhaps, this exploratory vehicle that successfully landed would Hao would leave something like, "One small step for you, one giant step for the tribe."

While he was thinking wildly, several figures appeared in the compound eyes of the explorer.

The tawny pipa-shaped body, bloated abdomen, head with compound eyes and a pair of slender claws are none other than the First Thunder Scorpion.

Previous behavior shows that they have obviously the ability to land on land. They may not be able to leave the water source for a long time, but there is no problem in staying at the water's edge for a short time under the cover of vascular plants.

As for their purpose of landing on land, no food was found nearby, proving that they did not come ashore to look for food. The answer is obvious. They chose to climb ashore to avoid the threat of predators.

In this lake, the only one capable of posing a threat to the First Thunder Scorpion is the Horseshoe Crab.

Judging from their vigilant expressions and their reactions of immediately fleeing when the pioneer mother scorpions appeared before, it seems that under the shadow of the ferocious tail blade of the horseshoe crab, the life of the first thunder scorpions is not easy.

In this era, who would have thought that the group they belong to, the Arachnids, would survive the mass extinctions of horseshoe crabs and survive to the era of Lin Yi's previous life, and still maintain a high level of Diversified, together with the existing horseshoe crabs known as horseshoe crabs, they form the remnants of the ancient lineage of the chelicerate subphylum.

But these are all things for later. Today, horseshoe crabs are still at their peak, and scorpions can only play soy sauce in the marginal ecological niche. Moreover, all of this has nothing to do with Lin Yi now - because these scorpions have already been discovered Explore work.
