I examined the history of evolution from the birth of life to modern humans from the perspective of resilience. In its 4.6 billion years of history, the Earth has undergone many major environmental changes. This has caused mass extinction of organisms, and each time, a small number of surviving species have adapted and dispersed in the new environment. Humans, too, have changed their lifestyles many times to adapt to the environment, starting with the change from arboreal to terrestrial at the beginning of their evolution, which enabled them to spread and prosper globally as we know it today. However, this modern material civilization has many problems as a by-product. In particular, the environmental changes that affect humanity as a whole and various modern diseases are deeply related to the rapidly changing modern environment. By looking back at the processes by which organisms have survived, this paper discusses why environmental adaptation has been possible and what is needed to achieve it, mainly from a biological perspective.
