Biological evolution is not only a process of natural selection, but also a process of survival of the fittest. Evolutionary adaptation includes two meanings: the improvement of individual viability and reproductive ability. Biological adaptability is aimed at a specific environment. When time and space change, when the environment changes, the adaptability of organisms will also change, thus causing the evolution or elimination of species.

Infiltrating the concepts of evolution and adaptation in teaching will help students understand the natural laws of species generation, community succession and survival of the fittest, as well as the changing process of organisms from simple to complex, from low to high, from micro to macro, thus forming a scientific concept of evolutionary development.

Evolution is the increasing structure and complexity of the material world, showing a diversified development trend. Evolution is change, evolution is inevitable, evolution is a process of constantly adapting to the environment, and human society is in the process of continuous evolution. This concept will bring students confidence in life and desire for a better life.

Evolution is a process of interaction between organisms and the environment, and it is a process of constantly adapting to the environment. Only when the creatures in nature adapt to the environment and find their own niche can they get the best development. Winners are not necessarily the strongest individuals, but the individuals who can best adapt to the environment. These viewpoints can enable students to actively cope with the changes in life, study and external environment, multiply their own adaptive choices, and make life more quality and valuable!
