"Darwin says we come from monkeys" was perhaps an understandable popular shorthand. The title refers to Charles Darwin's book "On the Origin of Species" published in 1859 that was the first scientific dissertation on evolutionary biology and natural selection. On the Origin of Species first appeared in 1859, and it remains a continuing source of conflict to this day. Even among those who reject its ideas, however, the work's impact is undeniable.
Darwin's theory was that species had evolved from simpler organisms by natural selection acting upon the variability of populations. This view was directly opposed to the doctrine of special creation by God and angered the Church and Victorian public opinion.
