Why is the development of living things reproduction rather than immortality?

Since accidental death due to non-life causes is inevitable, whether you are committed to Yu Yongsheng or not, you need to breed, otherwise the key to eternal life will be repair and adaptive change. After the system has developed to a certain extent, it is much easier to regenerate than to repair or modify it. Reproduction or rebirth provides opportunities for reorganization, provides diverse individuals, increases the possibility of adapting to the living environment, and further reduces the risk of extinction from the perspective of natural selection. The reproduction and development patterns of organisms are only the characteristics of survivors-today we can't see the eternal biological development patterns, perhaps because they are extinct, not the intelligent choice of organisms themselves. Even if the immortal development model successfully solves the problem of non-life death and extinction, it will eventually go extinct because of the termination or interruption of the resource system cycle of the living environment.
