First, novel coronavirus's mutation is a natural phenomenon, and the virus will mutate after time is extended:
Novel coronavirus is just a virus, but it has a long history. According to WHO scientists, this virus has a long history and has always existed in animals. Later, for some reason, it began to spread to humans. In fact, novel coronavirus has no harm to bats, pangolins and other animals, but after mutation, there will be a violent reaction in the human body. Therefore, from the perspective of evolution, novel coronavirus's mutation is a very normal phenomenon, because in the long evolutionary history, novel coronavirus has been constantly mutating, which is not a new thing, but a feature of novel coronavirus's evolution, but we call it mutation, just an update to the virus.
Second, the variation of novel coronavirus is related to the combination of various novel coronavirus, so there will be variation:
The variation of novel coronavirus is related to the encounter of different viruses. According to the research of scientists in China, novel coronavirus has different strains in Europe, America and Asia, so if these viruses meet together, it is likely that some variation will occur, which will lead to variation in novel coronavirus, so Japanese scientists will find out.
Three, novel coronavirus in different environments, will also promote its variation:
In addition, the scientific team of Leipzig Medical College found that it is likely that novel coronavirus will have different environments and produce new varieties of novel coronavirus. Therefore, it is not surprising that Japanese scientists have found this variation in various parts of the world.
