The significance of survival of the fittest in natural selection

"Natural selection, survival of the fittest" is an important concept in Darwin's evolution theory, which means that there is fierce competition among creatures in nature, and only those who adapt to the environment can survive. This concept is also called "natural selection". In nature, the competition between organisms is mainly reflected in food, living space and reproductive resources. Only those creatures that can adapt to the environment, resist natural disasters, find food and reproduce can survive and reproduce. This ability to adapt to the environment is determined by genes, so only species with excellent genes can survive and occupy an increasingly dominant position in the process of natural selection. Generally speaking, "natural selection, survival of the fittest" is a natural law, which shows the fierce competition among creatures and the importance of adapting to the environment. This concept can also be applied to social life, that is, only those who can adapt to the social environment and have excellent abilities and qualities can survive and succeed in a highly competitive society.
