An Internet meme is a hijacking of the original idea. Instead of mutating by random change and spreading by a form of Darwinian selection, Internet memes are altered deliberately by human creativity. There is no attempt at accuracy of copying, as with genes - and as with memes in their original version.

Science offers us an explanation of how complexity (the difficult) arose out of simplicity (the easy). The hypothesis of God offers no worthwhile explanation for anything, for it simply postulates what we are trying to explain. It postulates the difficult to explain, and leaves it at that.

The physicist's problem is the problem of ultimate origins and ultimate natural laws. The biologist's problem is the problem of complexity.

Textbooks describe DNA as a blueprint for a body. It's better seen as a recipe for making a body, because it is irreversible.

DNA is the wisdom out of the old days, and I mean very old days indeed.
