In honor of Darwin Day, writer Adam Gopnik penned a piece at the Nov. 19 Daily Comment site at the New Yorker: “The evolution catechism.” It’s about why politicians should be asked what they think about evolution: that is, whether they accept it or not. Some writers have argued that that question should be off limits, for who cares if a politician accepts evolution so long as they accept other scientific findings of greater import for both humans and the planet—global warming, vaccination, and so on? Gopnik’s reply is succinct:
But the notion that the evolution question was unfair, or irrelevant, or simply a “sorting” device designed to expose a politician as belonging to one cultural club or another, is finally ridiculous. For the real point is that evolution is not, like the Great Pumpkin, something one can or cannot “believe” in. It just is—a fact certain, the strongest and most resilient explanation of the development of life on Earth that there has ever been. And yet, as the Times noted, after Walker’s London catechism, “none of the likely Republican candidates for 2016 seem to be convinced.”
. . . What the question means, and why it matters, is plain: Do you have the courage to embrace an inarguable and obvious truth when it might cost you something to do so? A politician who fails this test is not high-minded or neutral; he or she is just craven, and shouldn’t be trusted with power. This catechism’s purpose—perhaps unfair in its form, but essential in its signal—is to ask, Do you stand with reason and evidence sufficiently to anger people among your allies who don’t?
. . . To oppose Darwinian biology is not to announce yourself neutral or disinterested or even uninterested. It is to announce yourself against the discoveries of science, or so frightened of those who are that you can be swayed from answering honestly.
Indeed. Gopnik falls down just a wee bit, though, when he has to explain why being against evolution is dangerous for a politician, for Gopnik sees the dangers in purely practical terms:
Evolutionary science is not abstract—evaluating reports of a “superbug” in Los Angeles, wrought immune by natural selection to antibiotics, means applying Darwinian principles as they go about their often scary work. The institutions of Big Science certainly have interests like any other, and the bureaucracies of science have orthodoxies of their own. But scientific reasoning is the basic way human beings achieve knowledge about their world.
The implication here is that politicians who reject evolution will, if elected, enact other policies that are both anti-science and have more dangerous consequences than those of, say, promoting or accepting creationism. And that’s not quite as clear, for there are many people who are perfectly happy to accept almost everything about science except evolution. After all, in the public eye, evolution has uncomfortable implications about humanity that most other sciences don’t share. Many creationists, however, are perfectly happy to get vaccinated.
So the question is this: does an opposition to evolution give you an idea of how a politician stands on other scientific issues of import? In general the answer is “yes”: in the absence of any other knowledge, opposition to evolution is statistically correlated with opposition to issues like global warming and scientific medicine, though not to others like the theory of relativity. The correlation, of course, is mediated through factors like religion and Republicanism, which nuture or support anti-science attitudes.
But in the case of a given politician, if you want to know his or her attitudes about important issues, ask them about those issues. Don’t just ask about evolution and blithely assume that someone who hedges about it will be anti-science in general. Ask about global warming. Ask about vaccination. Ask about their support for funding science.
And of course if we reject politicans because of the evolution litmus test, the test that Gopnik proposes:
Do you have the courage to embrace an inarguable and obvious truth when it might cost you something to do so? A politician who fails this test is not high-minded or neutral; he or she is just craven, and shouldn’t be trusted with power.
then every politician fails, because every politician is craven on one issue or another. Can you name one who isn’t? Obama, I believe, is craven about his belief in God, though I can’t prove it (that’s where evolution has the advantage, since we know the truth). Any politician who takes a stand that he or she doesn’t fully endorse, in order to garner votes, fails the Gopnik Test.
Still, I wouldn’t vote for a person who opposes evolution, for it does tell us unequivocally that someone can reject a palpable fact to get votes—a fact that I happen to have been deeply involved with for my whole career. To a scientist, that’s an unforgivable character flaw. If Hillary Clinton waffled on evolution (she won’t), I wouldn’t vote for her, either.
In the rest of the article, Gopnik trots out the evidence for evolution, which, as well all know, is multifarious and overwhelming. His description is quite good, and I have only a few quibbles. He seems to equate modern evolutionary theory with natural selection; he says that it’s controversial whether “everything we find in an animal is an adaptation,” or could be the results of genetic drift and accident (that’s not controversial; a lot of features in animal—and plant—genomes are clearly either the result of genetic drift or historical contingencies, like the presence of inactivated, ancient viral DNA; and he adduces only evidence from human fossils and DNA, neglecting all the evidence from biogeography, development, vestigial organs and genes, and so on. And I must insist that “flatworm” is one word, not two.
But these are simply the plaints of a captious biologist. In general, Gopnik’s description of evolution is excellent, as he’s one of the few non-science writers who seems to thoroughly grasp the concept and the issues it raises. He did, after all, write Angels and Ages, a nice book about the conjunction of Lincoln and Darwin (based on their simultaneous days of birth), which, as I recall, I blurbed. And it’s nice to see such an uncompromising defense of “Darwinism” (Gopnik doesn’t reject the term) in a mainstream magazine.
