Sir — Jeremy Woodley (Letters, September 19), in answer to the claim that the Theory of Evolution is 'still only a theory', writes that it is a theory of elegant explanatory power.

So it is, but it is more than a theory: evolution is a continuing process that can be observed in operation in the natural world today. The trouble with creationism is that it raises more questions than it answers. To say that the world was created by a mind of genius is no explanation at all unless you can also explain how this mind (unlike all minds we have any experience of) could exist without a physical brain, and how it was able to translate its conceptions into solid reality.
