Charles Darwin's 1859 theory of evolution by natural selection challenged literal readings of Genesis and began a lasting faith-and-science debate.
See it on the Bible & Christianity map →What it is
After his voyage on HMS Beagle (1831–1836), Darwin concluded that species change over vast spans of time as nature favors useful variations. On the Origin of Species (1859) sold out its first printing of 1,250 copies; The Descent of Man (1871) applied the idea to humans. Some clergy welcomed it; others objected. Catholic teaching later accepted evolution as compatible with faith (Pius XII, 1950), while many American fundamentalists rejected it, as in the 1925 Scopes 'Monkey Trial'.
Why it matters
It forced churches to decide how to read Genesis: as literal history, as theology told in story form, or both. The debate is still alive in schools and churches.
Sources and history
Darwin's books, notebooks and some 15,000 letters survive (Darwin Correspondence Project); genetics and the fossil record have since confirmed common descent, which is the scientific consensus.
Questions and debates
Darwin's own faith faded slowly; late in life he called himself 'agnostic'. The famous 1860 Oxford debate between Huxley and Bishop Wilberforce survives only in later, conflicting accounts.

▸Darwin's evolution and the faith debate challenged literal readings of Creation of the world (Genesis 1–2)Historical record
The connection
Darwin's theory implied that life, humans included, developed over millions of years from common ancestors, not in six days a few thousand years ago (Archbishop Ussher's chronology put creation in 4004 BC). Readers who took Genesis 1–2 as literal history faced a direct conflict; others read Genesis as theology about who creates and why.
When and where
England from 1859, after the Origin of Species; the clash peaked in America with the 1925 Scopes trial in Dayton, Tennessee.
Historical evidence
Sermons, reviews and church statements responding to Darwin survive in large numbers, along with Darwin's own letters on religion and the Scopes trial transcript.
Questions and debates
Whether science and Genesis truly conflict depends on how Genesis is read; Augustine already doubted literal days. Gallup found 37% of Americans still held recent human creation in 2024.
▸Darwin's evolution and the faith debate was resisted by Fundamentalism and the Scopes trialHistorical record
The connection
Darwin's accounts of evolution (1859) and human descent (1871) seemed to many to undercut Genesis and human dignity. By the 1920s fundamentalists made fighting evolution a crusade: William Jennings Bryan tied 'Darwinism' to German militarism and backed laws like Tennessee's 1925 Butler Act, which led directly to the Scopes trial.
When and where
United States, 1920s; Bryan's speech 'The Menace of Darwinism' (1921); the Butler Act, March 1925; the Scopes trial, Dayton, Tennessee, July 1925.
Historical evidence
The Butler Act and similar laws in Mississippi and Arkansas, the Scopes trial record, and Bryan's published speeches.
Questions and debates
Several authors of The Fundamentals accepted some evolution, so historians such as Ronald Numbers ask why anti-evolution became central only in the 1920s, and young-earth creationism later still.
