Charles Darwin proposed the theory of evolution by natural selection, which posited that species evolve over time through natural processes like variation and inheritance of adaptive traits. While influential, the theory was controversial as it contradicted the biblical view of fixed, designed species. The document argues that evolution has led to societal harms like abortion, eugenics, and racism. It claims Darwin experienced mental and physical anguish over his theory, questioning it on his deathbed. Overall, the document portrays evolution as being at war with God and urges teaching children biblical creationism instead.
