Thanks for the great responses, everyone. One counter-argument I can anticipate from creationists is that they accept microscopic but not macroscopic evolution. I don't see how one can be separated from the other myself, but as I say I'm not an expert.
I have heard that computer technology can at least in part be traced to the new ways of thinking that resulted from Darwin's theory. Does anyone know if this is true and, if so, can you suggest a possible chain of thought that leads from Darwin to the ENIAC?
