Evolution isn't just a take-it-or-leave-it story about where we came from. It's an epic at the centre of life itself. It tells us we are part of nature in every respect.

We know from astronomy that the universe had a beginning, from physics that the future is both open and unpredictable, from geology and paleontology that the whole of life has been a process of change and transformation. From biology we know that our tissues are not impenetrable reservoirs of vital magic, but a stunning matrix of complex wonders, ultimately explicable in terms of biochemistry and molecular biology. With such knowledge we can see, perhaps for the first time, why a Creator would have allowed our species to be fashioned by the process of evolution.

Once upon a time, growing up male gave little boys a sense of certainty about the natural order of things. We had short hair, wore pants, and played baseball. Girls had long hair, wore skirts, and, no matter how hard they tried, always threw a baseball just like a girl.

I am always struck by the fact that human awareness of our place in nature, like so much of modern science, began with the Industrial Revolution.

Biology is far from understanding exactly how a single cell develops into a baby, but research suggests that human development can ultimately be explained in terms of biochemistry and molecular biology. Most scientists would make a similar statement about evolution.

What evolution tells us is that we are part of a grand, dynamic, and ever-changing fabric of life that covers our planet. Even to a person of faith, in fact especially to a person of faith, an understanding of the evolutionary process should only deepen their appreciation of the scope and wisdom of the creator's work.

America's got a Darwin problem - and it matters. According to a 2009 Gallup poll taken on the 200th anniversary of Charles Darwin's birth, fewer than 40% of Americans are willing to say that they 'believe in evolution.'
