The human body itself is healthy, so how to explain the gene mutation and variation?

Although the human body itself is relatively healthy, under some time conditions, under the influence of some foreign objects, people will have new mutations, but this mutation is not necessarily harmful to people. Some human mutations are beneficial to human growth, so in this case, people will certainly not cause great diseases to their personal growth because of this short-term change. So even if there is a gene mutation, people will not necessarily get sick because of this gene mutation, which is the specific explanation of gene mutation and variation.

First of all, we need to know what conditions will affect gene mutation. The conditions affecting gene mutation are radiation, time, chemistry and even temperature. Because the change of these factors will lead to the mutation of human body cells, after all, the human body is constantly copying genes, and some genes will inevitably make some mistakes in the process of copying. Although we know that gene mutation will cause some crises to the human body, such as some harm to the human body and some threats to the human body, its advantages cannot be ignored.

For example, many years ago, there were only primitive animals. Of course, people didn't jump out of the cracks in the stone, but through these primitive animals, gene mutation was carried out step by step, and finally they could be transformed into more advanced animals. In addition, people may have tails before, but the existence of tails is not conducive to human daily life, so in the continuous evolution, this kind of thing will disappear because of mutation.

So this genetic mutation, genetic variation, actually gives people a reason to survive. If people are not constantly adapting to changes in the environment, there will be higher-end creatures to replace human beings. But it is precisely because of these beneficial genetic changes that people have such advanced thoughts and behaviors.
