Few scientists have been as influential and controversial as Charles Darwin. Darwin’s theory of evolution by natural selection not only reinvented modern biology in all its branches but also rocked theology and religion in ways that resound to this day. Does Darwinism inevitably lead to atheism, as critics (and some proponents) of natural selection claim? Is evolution by natural selection truly a scientific theory, worthy of being taught without qualification in public schools? Or can one be both a Darwinist and a committed Christian? What did Darwin himself think?
