Did I just hear someone say (see comments to my piece below about the Nightline debate) that if you believe in strict interpretation of Genesis species don't change over time? Where does it say something like that in Genesis?
Quite the contrary. The Book of Genesis is a shockingly counterintuitive religious document in that it specifically announces in its second sentence that God did not create a finished world at once. Instead He began with some kind of primordial matter and then began a staged process, including stages separated by time, of bringing it to completion.
In fact, the very first question that any serious student of the Bible asks is: why would an omnipotent Creator choose NOT to create all at once?
As to the creation of Man, it says specifically that he was fashioned out of some primal component of the Earth itself. If you ever stop to think about how shockingly this runs counter to the simple unscientific religious impulse you will get an inkling of just how subtly sound a philosophical work the Bible is - and it might just give you a clue why most of the smartest people in history have believed it and been moved by it to inspiration and passion.
