Bodies are not just instruments for carrying genes around; genes are recipes for making bodies. Bodies are the point. Genes are the tools.
This is the upshot of a fine lecture by Oxford theologian Keith Ward. I have thought something like this as a rebuttal to the "selfish genes" view, but he put it much better. This lecture is available from the Gresham College online service. (For that matter, I highly commend Gresham College, an ancient adult education foundation in London.)
