From The Boston Globe:
On a recent Monday afternoon, the distinguished Harvard biologist Edward O. Wilson was at his home in Lexington, talking on the phone about the knocks he’s been taking lately from the scientific community, and paraphrasing Arthur Schopenhauer to explain his current standing in his field. “All new ideas go through three phases,” Wilson said, with some happy mischief in his voice. “They’re first ridiculed or ignored. Then they meet outrage. Then they are said to have been obvious all along.” Wilson is 81, an age at which he could be forgiven for retreating to a farm and lending his name to the occasional popular book about science. Over the past year he’s tried his hand at fiction writing, publishing a novel about ants — his scientific specialty — and landing a short story in The New Yorker. But he has also been pressing a disruptive scientific idea, one he reckons is currently in phase two of the Schopenhauer progression: outrage. What Wilson is trying to do, late in his influential career, is nothing less than overturn a central plank of established evolutionary theory: the origins of altruism. His position is provoking ferocious criticism from other scientists. Last month, the leading scientific journal Nature published five strongly worded letters saying, more or less, that Wilson has misunderstood the theory of evolution and generally doesn’t know what he’s talking about. One of these carried the signatures of an eye-popping 137 scientists, including two of Wilson’s colleagues at Harvard.
His new argument, in a nutshell, amounts to a frontal attack on long-accepted ideas about one of the great mysteries of evolution: why one creature would ever help another at its own expense. Natural selection means that the fittest pass down their genes to the next generation, and every organism would seem to have an overwhelming incentive to survive and reproduce. Yet, strangely, self-sacrifice exists in the natural world, even though it would seem to put individual organisms at an evolutionary disadvantage: The squirrel that lets out a cry to warn of a nearby predator is necessarily putting itself in danger. How could genes that lead to such behavior persist in a population over time? It’s a question that bedeviled even Charles Darwin, who considered altruism a serious challenge to his theory of evolution.
