It is not advisable to make the body huge, to give full play to the advantages of your body, this is the thinking of the organism in the evolutionary trend, and further choice, and this choice prompts the creature to begin to limit its body size, this body type is not the fat and thin that many girls care about now, but inhibits growth, before the failure of the evolution of the giant biology, all creatures in addition to evolving their own body functions are still constantly gigantic their own body, how big they grow, it all depends on how much food he can eat. Pen ~ fun ~ pavilion www.biquge.info and the reason why they can continue to make them huge is that the cells in the body continue to divide, so that their growth is a matter of course. There are examples of animals in nature who can destroy their opponents by their numbers, because they have sharp mouthparts that can divide and eat defeated opponents, but between these relatively primitive cells, they do not form these sharp mouthparts, and they can only destroy opponents if they are larger than their opponents. However, if the body size is not enough, it is difficult to turn against the customer, so in order to destroy these small cells, it is necessary to generate a large cell, so starting from the heart, those primitive cells are slowly engulfed. Gradually spread new cells to the whole body, this process is simple to say, but it takes time for new cells to occupy the entire body, after all, these new large cells are not like the original small cells can divide indefinitely, they divide to a certain number and do not have the ability to continue to divide, so they occupy the place these cells will be fought for by these primitive cells after death, and I don't know how long it took for these cells to control the new body This process is very slow, slow to this day, it is still not over, these new large cells have not controlled the body of the organism until nowAlthough all our actions have been controlled by these large cells, there are still many small cells that are fighting for the sovereignty of the body, and these replaced cells are the bacteria in our mouths now. Organisms that have evolved in nature can use many ways to fight, but in the body of living organisms there is only a battle between large cells and small cells of the same body type, and whoever has a large body can destroy the other party, but after the large cells lose their vitality, they are occupied by these cells again like the original biological fusion substance, and the battle between these cells and primitive cells is like this, as the survival and reproduction of organisms continue to continue, and it has not ended until today, even in the tiniest genes, these new cells can suppress those primitive cells, and the nature of many diseases will show recessiveness, if not, or holding each other will show dominance in the genes.

Of course, in addition to the cells in these organisms, the cells outside the organisms are also competing for the body of the organism, after all, life is to constantly change the world from the beginning, and for any cell, all the external environment is nature, and they are the goal of their change. For these foreign cells, these new cells, will be very decisive to phagocytosis, if their phagocytosis can not kill these cells, there is a chance that there will be more powerful cells to complete this task, but the premise is that these cells are really smaller than these cells, if their volume is larger than these cells, and they have not died, those cells in the body will face a devastating blow. When foreign cells defeat these native cells, they can cause inflammation in certain parts of the body, causing lesions and even ulceration. The cells that come out of the body don't do that, they devour the cells, but they don't destroy the outside of the body, because the body is theirs. However, the price of their victory is also very serious, after all, it is those cells that make up the body's immune system, and when they are destroyed, the body loses its defenses, and after losing its defenses, the body of the organism will be infiltrated by these foreign cells.

Of course, with those small cells being taken the initiative by large cells, the creatures also got the purpose they wanted before, that is, to limit the size of the body, and after the body size was restricted, the size of the creatures was roughly controlled, because the volume difference was not much, so they could communicate with each other, that is, after the size was restricted, the creatures really appeared that people have words, and beasts have beast language. The size of all land animals is restricted, carnivores limit their size because they are afraid that they will not eat enough food to make themselves food for other creatures, and herbivores because the carnivores' bodies are flexible, they can chase them, they also have to lose weight, of course, there may be some people who do not give up, still think that they can take care of these little ones if they are big enough, then they will face more joint attacks of small carnivores, carnivores unite, herbivores must limit their bodies so that they can escape this danger, although their food will not move。

Of course, after this kind of cell has fought for the sovereignty of the animal's body, it has also brought about something that all intelligent beings are afraid of now, that is, death, after the body cells multiply to a certain extent, they lose their activity, and after losing their biological activity, the body of the organism will naturally die. The struggle between the newborn cell and the primitive cell goes on even though the organism is already considered dead.
