Darwin's theories influence extinction thinking

Darwin revolutionized extinction thinking by challenging the prevailing catastrophism theories of the early 19th century. While catastrophism suggested extinction was caused by sudden geological events, Darwin argued that extinction occurs gradually over long periods due to environmental changes and interspecies competition. This shift in perspective led to a new understanding that extinction is a predictable, long-term process rather than a catastrophic event. Subsequently, individuals began focusing on managing populations for maximal fitness and preventing extinction by addressing slow-moving risks like environmental change and competition, as opposed to catastrophic events. Darwin's concept that extinction is a slow and predictable process fueled discussions on preventing extinction and managing existential risks in the late 19th century.
