On this day in 1859, Charles Darwin published his ground-breaking book ‘On the Origin of Species’. Darwin’s book introduced the scientific theory that populations evolve over the course of generations through a process of natural selection. It presented a body of evidence that the diversity of life arose by common descent through a branching pattern of evolution. Darwin included evidence that he had gathered on the Beagle expedition in the 1830s and his subsequent findings from research, correspondence, and experimentation.
The concept of evolution revolutionised science, and was very unpopular at its time for its supposed ignoring of God’s role in man’s history. His ideas were widely ridiculed and satirised (see picture), however now his thinking is the foundation of modern scientific thinking.
