Several high-profile evolutionary biologists in the twentieth century were committed organicists. Conrad H. Waddington, the British geneticist was one, trying to simulate Lamarckian processes through orthodox genetical approaches. Another was the well-known American paleontologist and scientific popularizer Stephen Jay Gould, who promoted morphology over adaptation. And a third was the founding populational geneticist, American Sewall Wright. He argued that random processes, genetic drift, could and would lead to major adaptive breakthroughs. Philosophers likewise embrace organicism, including the British John Dupré and the American philosophers Jerry Fodor and Thomas Nagel. Nagel in particular has been highly critical of Darwinian theory, thinking it to be crude materialism masquerading as science. Expectedly, the Darwinian mechanists have struck back, confirming the suspicion that we have paradigm differences at stake. The two sides, mechanism and organicism, defend their positions with alternative reasons. For the mechanists, the triumphs of their approach trumps all. The double helix is a popular example in support of mechanism. For the organicists, the special place of humans trumps all. We are superior and no further argument is needed.
