In this talk, Dr. Keith Lockitch of the Ayn Rand Institute explores Darwin’s life and work, focusing on the steps by which he came to discover and prove the theory of evolution by natural selection:
The theory of evolution is often disparaged by its opponents as being “just a theory” — i.e., a speculative hypothesis with little basis in hard, scientific fact. But this claim carries with it the implied accusation that Charles Darwin was “just a theorist” — i.e., he was merely an armchair scientist and that his life’s work was nothing more than an exercise in arbitrary speculation. A look at Darwin’s pioneering discoveries, however, reveals the grave injustice of this accusation. Darwin was not “just a theorist” and evolution is not “just a theory.”
