Here is a great point made by Stephen Godfrey (Paleontologist) and Christopher Smith (a Baptist minister) in their new book Paradigms on Pilgrimage, one of a slew of new books by Christian authors supporting evolution. It addressed one of the primary objections Creationists have to evolution: that it is based on pain and death and, thus, not a method worthy of God. Although I have many quibbles with that Creationist position, here is what Godfrey and Smith say:
"Far from being dependent on death, the evolutionary process as seen in the fossil record is actually the antidote to death. If new species were not formed by the process of genetic variation, there would be no survivors when environmental conditions did change and existing species proved so poorly adapted to the new conditions that they became extinct. So death is not necessary for evolution, but evolution has been necessary for the continuation of life." (pages 167 and 168 emphasis mine)
