The proponents of Marxian biology appear in unexpected places. In the early disputes over evolution, the most effective aid to the Marxian line came from the humanitarian but conservative Christians, who not only rejected evolution on theological grounds, but who also looked with horror on the amoral viciousness of what they took to be natural selection. Marx himself had also objected to the competitive aspects of natural selection, so both his followers and the more conservative religious groups found themselves on the same side. In fact, the Marxian biologists of the last seventy-five years had their pathways made smooth by the Victorian fundamentalists.
