Sure, that's perfectly fine. And that's one of the reasons I don't see a conflict between evolutionary theory and the Bible. The book of Genesis dealt with the mechanics of creation in only a superficial sense - the important stuff was who did the creating, and what was the end result. The aim of science is to reduce - complex phenomena to simple phenomena. So science tries to describe the physical process of how creation occurred using the physical evidence available. It's not a "proof" - just a best guess based on our current knowledge (same as all other science).
That's why I don't understand the conflict between the Bible and evolutionary theory - they simply don't address the same issue.
If you interpret the Bible loosely to allow Darwinesque evolution, then you are, in effect, interpreting it loosely enough to allow that Jesus was not born of a virgin, the miracles are not real, three was no bodily resurrection, there is no heaven or hell, etc.
So--take your pick--Jesus is Lord, or Darwin nailed it. You CAN'T have both.
