The evolution of insect swarms from XNUMX million years ago

Chapter 337 Comet Impact
The radio signal that was transmitted across almost the entire star system fell silent temporarily. It seemed that this series of events was indeed somewhat unexpected, and the other party did not continue to respond in a short period of time.

However, it seems that the other party does not have much chance to digest all of this for the time being - the icy comet with the back half filled with electric rocket thrusters has come quite close to the habitable planet where the other party is temporarily staying, and has entered the final impact stage.

While watching everything in front of him through the observing compound eyes of the reconnaissance star scorpion, Lin Yi's consciousness was filled with memories of his previous life that had faded due to a long period of time. The various impacts of the Younger Dryas event on later research and speculation also emerged one by one.

The Younger Dryas event was the extinction event closest to the time of his previous life and in some sense the one with the greatest impact. In a sense, it was indeed not just an extinction, but also an opportunity, an opportunity to destroy and then rebuild, to be reborn.

There have been various speculations about the cause of the Younger Dryas event in later generations, and comet impact is only one of them. However, although this extinction event was not particularly large in scale, it still caused the extinction of many species and even changed everything on Earth forever.

This incident occurred only 12,000 years after Lin Yi's previous life, which is a short time in terms of biological evolution. Almost everything about Lin Yi's previous life was a direct result of that incident.

The intensity of the extinction event itself was not enough to cause much damage, but the reality is that a large number of large animals became extinct worldwide, including the famous saber-toothed tigers, mammoths, etc.

Unlike ordinary extinction events, before the Younger Dryas event, humans, late Homo sapiens who were basically the same as later modern humans at the genetic level, already had a complete gathering and hunting model, and had become a force that could not be underestimated at that time.

Even if the ability to change the environment and cause large-scale species extinction was not fully acquired until the agricultural age or even the industrial age, the primitive tribes that were still in the gathering and hunting age at that time were still quite weak. But for the fragile ecological environment in the extinction event, this little power was enough.

As the saying goes, if you survive a disaster, there will be a final blow. For those large animals struggling for extinction, human hunting is the final blow, or, in other words, it should be said that under the circumstances at the time, it was the nail that sealed the coffin to prevent them from resurrecting.

But the power of extinction events does not favor any species. Perhaps some unlucky ones are targeted, and some lucky ones escape by accident, but for most creatures, all are treated equally.

In a sense, humans in the gathering and hunting era were just an unprecedentedly powerful group of top predators, and as large animals, they were still subject to fatal effects.

At the most critical moment, there were probably only a few hundred adults with reproductive capacity left worldwide. But this is why this incident was both a disaster and an opportunity - it was the stimulus of this incident and the shortage of food that allowed primitive agriculture to begin to emerge!
The time when the oldest large settlements, which can be called countries rather than tribes, appeared roughly coincided with the end of the impact of the Younger Dryas event. And this is not a coincidence in one or two places, but a universal one.

With this initial foundation, the subsequent Industrial Revolution and other events took place, realizing the transformation from a simply a strong social top predator to a civilization that is almost beyond the food chain and ecological cycle.

This is why Lin Yi inexplicably felt a sense of emotion about the actions of the remnants of the exploration fleet - if he had not participated, perhaps the other party could have destroyed and rebuilt, and achieved the task of preserving the fire of the Ezki civilization. A small natural extinction event created human civilization, and this "New Dryas" that will be artificially created will make the remnants of the Ezki civilization exploration fleet reborn again on the ruins, which makes people sigh.

But no matter what, he must control this group of strong men as much as possible - although he will not deliberately sabotage the comet impact plan to force the opponent to rely on him, but he does not intend to continue watching the subsequent series of processes.

The comet is already quite close to the orbit of the life-bearing planet and has entered the final deceleration stage. The electric rocket engines in front will instantly consume the accumulated energy, and a small amount of working fluid will be ejected at an astonishing speed under acceleration, helping the comet to achieve the final deceleration with extremely high specific impulse.

The gravity of the planet gradually takes effect, and the comet's track gradually slows down. It begins its final deceleration along the planet's orbit, in the opposite direction of its rotation. The gravity of the planet is still like an invisible rope, pulling and slowly decelerating under the action of its rotation.

According to the trend, it won’t be long before the comet falls into the target planet’s sparse atmosphere and impacts somewhere, forming an alien version of the Younger Dryas event, which in some sense will change the ecosystem environment for a short period of time.

An overly dry and hot environment would be improved by the impact - the thick icy shell would bring in a lot of water, while the dust stirred up by the impact would form a protective layer to a certain extent, reducing the strong impact of the star's light.

After all, the main sequence star of this star system is an F-type star. Compared with a G-type yellow dwarf like the Sun and a K-type orange dwarf like Enceladus, the fusion reaction is much more violent, and the strong light and heat do require a certain degree of shielding.

And if controlled accurately, a series of chain reactions may maximize its effect, just like the Younger Dryas event, allowing the planet's temperature to reach a level similar to that of Ezekiel's home planet in a short period of time.

During the Younger Dryas event, the comet did bring a lot of water. Even though the Earth is already rich in water, it still had a significant impact. It may not have been evident at the time of the extinction event, but it was almost certainly evident after the impact was basically over.

After the impact of the Younger Dryas event basically ended, the continent within a certain range probably experienced the last round of disasters - the recovery of temperature caused a large amount of glaciers to melt, resulting in large-scale floods and waterlogging disasters.

During that period, early civilization had been initially established. In the West, there were legends about the "Great Flood", while in the East, there was the story of Dayu's flood control. According to speculation, it is very likely that both were related to the melting of glaciers after the Younger Dryas event.

According to current calculations, this collision will have a significant impact on the environment of this planet. As for whether this impact will be beneficial or detrimental to the remnants of the Ezki exploration fleet and to Lin Yi, it is unknown.
