We believe the ice sheet was not around all the time. It was only around during cool snaps of the climate.

You can't tie a rope around the ice sheet. You can't build a wall around the ice sheets.

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.'

For much of history it was possible to believe that the great diversity of life on Earth was a fixed creation, that the living world had never changed. But when the first stirrings of industry demanded that fuel be dug from the earth and hillsides be leveled for roads and railways, the Earth's true past was dug up in abundance.

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.
