Chapter 752: Chapter 753 The Origin of Variation
The Zerg were born on a terrestrial planet called 'Tyr'. There are no oceans on this planet, only lakes scattered around the planet. The Zerg were originally conceived in these large and small lakes.
However, the Zerg in that period could not be regarded as Zerg, but barbarians without wisdom. From micro-scale single cells to macro-scale organisms, deception, fighting, camouflage... In order to survive, it can be said that other species with complex ecosystems are the same on this planet. Yes.
Every once in a while, he will be baptized by ionizing radiation. The radiation intensity is not high, just to the extent that it destroys the genes of a wide range of organisms.
The reason is that the massive object around Tyre is not a star, but a relatively slow-to-turn neutron star. The pulse beam of the neutron star does not shine directly on Tyre, but there is still diffuse ionizing radiation to Tyre.
At the beginning, those creatures that climbed to the land could not adapt to the land environment. Even if the ionizing radiation of the neutron star was filtered by Tyre's atmosphere and the radiation weakened a lot, it is inevitable that a large number of creatures will die due to radiation. Only aquatic organisms can survive, because the water body is also Natural radiation barrier.
The seeds are still there, and there will be aquatic creatures climbing up the land one after another.
Tyre is a planet with a land area larger than the water body area. It has a wider living space on land. As long as the survival instinct of the creatures on Tyre is not lost, they will not live in the lake.
Not afraid of life and death, just for survival!
After a long period of extinction and reincarnation of land creatures, some creatures on Tyre finally evolved genes with strong radiation resistance, and climbed to explore and conquer the land.
Although after a long time, genes with strong resistance to radiation have finally evolved, strong resistance is only strong, which does not mean complete immunity.
Before awakening wisdom, there will be information exchange between insect nests, because this can improve the probability of survival. Even for beasts, communication is a very useful means of survival, such as lions and tigers on the earth, who will consciously leave excrement on the edge of the territory and warn of invasion outside the territory. .
Through pheromonic communication between nests, pheromones are left on a worker bee, and worker bees are used as messengers to deliver 'heromone letters' to complete the information communication between nests.
The improvement of wisdom means the increase of communication complexity, and the amount of information transmitted between peers is increasing.
Such an information circulation network has built a primitive civilized society. The insect nest in this social system is the original command class of the Zerg, and the wise leaders in the class are respected as the 'dominance'.
The power of the group is very strong, especially after the emergence of 'civilization', which is still other creatures in the category of 'beast' and can't fight against the Zerg at all. Because they were successfully promoted to 'civilization', the Zerg became the top and least suspense predator in Tyre.
However, no matter how powerful the creature is, it is very powerless to face natural disasters.
Reality woke up the Zerg from the dream of being invincible in the world. An asteroid with a diameter of 30 kilometers hit Tyre, and the shock wave destroyed all the creatures in an Australian area, and none of the Zerg there were spared.
Dust clouds have covered the sky for 20 years, accompanied by a severe cold that has lasted for 20 years. Ionizing radiation has weakened by dust clouds, and the whole ecosystem has entered the era of 'ecological brakes'. I don't know how many powerful species have become extinct because they can't survive the cold.
In the face of nature, all living things are so fragile.
The Zerg almost perished because of this. If it hadn't been for the Lord's call on all the same commanding worker bees to dig underground and let the whole Zerg hide in the ground and rely on the ground heat to survive the cold for 20 years, I'm afraid the Zerg would have been extinct.
However, even if they hide underground and rely on geothermal heat to survive, the situation of the Zerg is not very good, because there is no food and the extinction of a large number of species on the ground means that the Zerg have lost their food source, and many nests starved to death as a result. There is nothing they can do. The brain activity consume too much energy, but they can't find it. When it comes to new sources of biological energy, you can only starve to death.
As for the surviving Zerg, they were forced by the environment to learn to plant and survive under the ground for 20 years through a fungus that absorbs geothermal energy.nove(l)bi(n.)com
