We know that for more than half a century social Darwinists used ideas of “natural selection” and “survival of the fittest” to justify racist and inhumane policies like eugenics, anti-immigration laws, and forced sterilization. William Jennings Bryan—a religious conservative who was also a political progressive—championed the creationist cause at the Scopes trial largely because of his abhorrence of this political program. Today’s champions of evolution are quick to declare social Darwinism a crude distortion of Darwin’s theories. As one of my college professors put it, “They were using science for ideological ends. That’s not going on today.”
