Reef Madness

November 22, 2004
Few questions in 19th-century science aroused more controversy than the origin of coral reefs. Charles Darwin posited that the corals grew upon sinking land forms, a theory widely accepted despite its lack of empirical evidence. Enter Alexander Agassiz (1835–1910), son of the renowned naturalist Louis, whose earlier dispute with Darwin over evolution tarnished his reputation as a scientist. A meticulous researcher, Alexander disapproved of Darwin's "intuitive leaps"; he believed that proper science must work "through eyes-on observation and the tireless accumulation of reliable information." To this end, he spent the last 25 years of his life visiting every major reef formation on the planet. But though he gathered a wealth of evidence that seemed to refute Darwin, he never published his findings. By the 1950s, when technology enabled researchers to drill for deep coral samples, data proved that Darwin had guessed right after all. Dobbs (The Great Gulf
, etc.) clearly sides with Agassiz in this story of clashing intellects and egos, arguing that Alexander's aversion to confrontation and his emphasis on methodology sprang from the embarrassment caused by his father's stubborn creationism, as well as from annoyance at Darwin's stoking of his own reputation. That Alexander's failure shows Darwin's theory to be all the more brilliant may be an unintended irony of this engrossing chapter in the history of modern science. Agent, Charlotte Sheedy.
