<h4>Chapter 752: Chapter 753 The Origin of Variation</h4>


    The Zerg were born on a terrestrial called ''Tyr''. There are no oceans on this, onlykes scattered around the. The Zerg were originally conceived in theserge and smallkes.


    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, camouge... In order to survive, it can be said that other species withplex ecosystems are the same on this. 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 rtively 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 thend could not adapt to thend 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 arge 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 thend one after another.


    Tyre is a with and arearger than the water body area. It has a wider living space onnd. As long as the survival instinct of the creatures on Tyre is not lost, they will not live in theke.


    Not afraid of life and death, just for survival!


    After a long period of extinction and reincarnation ofnd creatures, some creatures on Tyre finally evolved genes with strong radiation resistance, and climbed to explore and conquer thend.


    Although after a long time, genes with strong resistance to radiation have finally evolved, strong resistance is only strong, which does not meanplete immunity.


    Therefore, whenever Tyre''s rotation turns towards the neutron star and the side of the wees daylight, the terrestrial creatures in that area will mutate on arge scale.


    Most of the mutations are very deformed, and even survival is a problem, but there are also a few creatures with very advanced mutations. They are the unparalled lucky ones, Africans who have been smuggled to Europe by lottery.


    Through thew of natural selection in the ecosystem, species that can''t adapt to survival will be destroyed. Under the big waves, the biological poption on Tyre has be more and more advanced, and the species evolves far faster than others withplex ecosystems. The species on others evolve in ten thousand years, while on Tyre But it is measured by years.


    On Tyre, creatures of the size of ants may evolve into powerful predators of mammoth size and dominate one side as long as they are lucky enough to pass through 50 or 60 years.


    However, such apetitive environment is not easy to evolve intelligent species. Therge-capacity brain will upy a lot of nutrients in the body, which will make it impossible for intelligent species topete physically over other organisms.


    The manufacture of tools does not happen overnight, and the umtion of knowledge also requires a process, but biologicalpetition is always at all times, and the rapid evolution brings a much more intensepetitive environment than other ecosystems.


    This led many people in Tyre to win the ''brain expansion'', a smart species that was signed on, and went to destruction because they could not adapt to the fierce biologicalpetition.


    But there are exceptions to everything. A special intelligent creature is conceived on Tyre and stands firm in the fiercelypetitive ecosystem.


    They are the original prototype of the Zerg - the nest.


    The appearance is simr to volcanic. By breeding a small creature ''worker bee'', the nest is responsible for producing worker bees and making food that is easy for worker bees to digest, while worker bees are responsible for hunting and guarding the nest. Their rtionship is simr to ant colonies.


    At this time, there is no Zergwork, and they rely on biopheromones to maintain their rtionship with each other.


    With enough nutrients and no need to participate in the fierce survivalpetition, the wisdom of the nest has been opened.


    Before awakening wisdom, there will be information exchange between insect nests, because this can improve the probability of survival. Even for beasts,munication 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 pheromonicmunication between nests, pheromones are left on a worker bee, and worker bees are used as messengers to deliver ''heromone letters'' toplete the informationmunication between nests.


    The improvement of wisdom means the increase ofmunicationplexity, and the amount of information transmitted between peers is increasing.


    Such an information circtionwork has built a primitive civilized society. The insect nest in this social system is the originalmand ss of the Zerg, and the wise leaders in the ss 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 sessfully 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, apanied by a severe cold that hassted 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 be 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 samemanding 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 arge 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 ites 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 nt and survive under the ground for 20 years through a fungus that absorbs geothermal energy.
