Michael Shermer: A Skeptic's Take on the Public Misunderstanding of Darwin
[Dr. Michael Shermer is the Founding Publisher of Skeptic magazine (www.skeptic.com), the Executive Director of the Skeptics Society, a monthly columnist for Scientific American, the host of the Skeptics Distinguished Science Lecture Series at Caltech, and Adjunct Professor of Economics at Claremont Graduate University. ]
On July 2, 1866, Alfred Russel Wallace, the co-discoverer of natural selection, wrote to Charles Darwin to lament how he had been “so repeatedly struck by the utter inability of numbers of intelligent persons to see clearly or at all, the self acting & necessary effects of Nat Selection, that I am led to conclude that the term itself & your mode of illustrating it, however clear & beautiful to many of us are yet not the best adapted to impress it on the general naturalist public.” The source of the misunderstanding, Wallace continued, was the name itself, in that it implies “the constant watching of an intelligent ‘chooser’ like man’s selection to which you so often compare it,” and that “thought and direction are essential to the action of ‘Natural Selection.’” Wallace suggested redacting the term and adopting Herbert Spencer’s phrase “survival of the fittest.”
Unfortunately, that is what happened, and it led to two myths about evolution that persist today: that there is a prescient directionality to evolution and that survival depends entirely on cutthroat competitive fitness.
Contrary to the first myth, natural selection is a description of a process, not a force. No one is “selecting” organisms for survival in the benign sense of pigeon breeders selecting for desirable traits in show breeds or for extinction in the malignant sense of Nazis selecting prisoners at death camps. Natural selection is nonprescient—it cannot look forward to anticipate what changes are going to be needed for survival. When my daughter was young, I tried explaining evolution to her by using polar bears as an example of a “transitional species” between land mammals and marine mammals, but that was wrong. Polar bears are not “on their way” to becoming marine mammals. They are well adapted for their arctic environment.
Natural selection simply means that those individuals with variations better suited to their environment leave behind more offspring than individuals that are less well adapted. This outcome is known as “differential reproductive success.” It may be, as the second myth holds, that organisms that are bigger, stronger, faster and brutishly competitive will reproduce more successfully, but it is just as likely that organisms that are smaller, weaker, slower and socially cooperative will do so as well....
