Did Darwin believe in extinction

Yes, Charles Darwin accepted the concept of extinction. He recognized that species could become extinct due to various factors, including environmental changes and competition for resources. In his work, particularly in "On the Origin of Species," he discussed how natural selection could lead to the decline and eventual disappearance of species that could not adapt to changing conditions. Darwin's observations of the fossil record also supported the idea that many species had existed in the past but no longer existed today.
