Charles Darwin was a consummate scientist – meticulous and rigorous. He spent nearly 20 years sifting his research, honing his analysis and polishing his prose before publishing his groundbreaking work, On the Origin of Species, in November 1859.1

Darwin’s slim volume was what we would call a ‘game changer’; a revolutionary work that fundamentally altered the way human beings see themselves and the natural world. Today most of us are familiar with his theory of ‘natural selection’ – the foundation of modern evolutionary biology. But 150 years ago, Darwin was sailing into choppy waters. The Church of England set rigid boundaries and his thesis was clearly offside – a challenge to the orthodox view that humans were a separate, unique part of God’s creation and that all life was divinely concocted and unchangeable.
