Steve, evolution does not explain everything. The Theory of Intelligent Design holds that certain features of the universe and of living things are best explained by an intelligent cause, not an undirected process such as natural selection. This is not the same as Creationism. What's more, as it was the intellectual trend in Darwin's day to transfer the model for the study of the natural sciences to social science, Darwinism led to Social Darwinism. Social policies reflecting the "survival of the fittest," applied to social affairs have been a complete disaster except for those in the privileged classes and defy anthropological evidence that man survived his early trials through cooperation rather than competition within the group. How ironic is it that so many conservatives still ascribe to Darwinistic social policy while they reject science in favor of religion?
