There were several reasons why humans could not live forever: 1. ** Gene Restriction **: - Genes controlled cell division. There was a telomere structure at the end of the human gene. Every time a cell divided, the length of the telomere would decrease. When the length of the telomere reached zero, the human gene would become chaotic and lead to death. Although the existence of telomerases could repair and compensate telomeres, this mechanism could not make humans immortal. - From the perspective of genetic transmission, most organisms adopted half-inheritance, and the genes of the offspring came from both parents. The genes were defective and would try to suppress their expression in the next generation. In order to find a better half of the genes for stable inheritance, it was necessary to regularly eliminate old individuals. - The lifespan of every living creature had been marked in the genes. Living creatures were just carriers of genes, and genes were for their own continuation. Living creatures 'eternal life was not conducive to the healthy transmission of genes. 2. ** Reproduction and population balance: - The resources on Earth were limited. If creatures were to live forever and continue to produce offspring, the population would exceed the limits of nature and eventually die out. This did not meet the needs of genetic continuation. - There was a balanced relationship between reproduction and lifespan. The shorter the lifespan of a creature, the stronger its reproductive ability. 3. ** Body size and genetic factors **: - The size of a creature had an impact on its lifespan. A larger creature would be less threatened by external threats and had stronger defense and vitality, but this would not allow a creature to break through the limit of immortality. - Biological inheritance was also one of the factors that affected lifespan. The novel " Ten Years of Death " is equally exciting. Everyone is welcome to click and read it!
