He proposed that natural selection is the primary mechanism of evolution.

Briefly: Darwin's key contribution was the theory of evolution by natural selection (descent with modification). He was not the first to notice that organisms change, he did not explain heredity (Mendel did), and he did not rely on Lamarckian inheritance as his main mechanism.
