Descartes: Religion

In part five of Descartes' Discourse on Method, within his discussion of creation, he makes the statement "their nature is much easier to conceive when we see them begin to grow little by little in this way than when we only consider them as fully complete." This is in reference to the origin of things now in existence. To me, this statement has profound implications towards the justification of evolution within the bounds of Christianity. If he is making the claim that creation began with nothing other than the "form of chaos" within the bounds of the God-created laws of nature, than evolution from that beginning seems to be a plausible explanation.
