The prehistoric mass extinction was attributed to the sudden change of environment (such as the impact of asteroids on the earth), which led to the extinction of many creatures because they could not adapt to this sudden change.

At present, the reason for the decrease of biodiversity is the influence of human beings. For terrestrial biological species other than human beings, human influence has become a part of environmental impact. With the great improvement of human killing ability, if animals can't adapt to this environmental change, they may become extinct.

In the current earth environment, the interests of human beings have largely become the goal of species evolution. Only those gene mutations that meet human needs can gain genetic advantages, such as human breeding process, and those rice with high yield and insect resistance are selected and planted in large areas. The evolutionary success of these rice plants is due to their adaptation to human needs. For another example, humans kill some creatures because of their special needs (meat, fur, etc.). ), and if these creatures can't effectively adapt to human hunting and extinction, it is likely to lead to extinction. Animals that can quickly evolve countermeasures, such as cockroaches and mice, can still adapt to the earth's environment.

Therefore, the similarities between the prehistoric extinction and the current decline in biodiversity are in line with the evolutionary point of view. The difference is that human demand has become the main environmental change of species evolution in modern biological evolution. Some species can adapt to this change and achieve evolutionary success, but those who cannot adapt to this change may become extinct.
