Evolution's Captain

September 1, 2003
Readers familiar with how Darwin developed his theory of evolution will recognize the HMS Beagle as the ship that took him on his research expedition, but that's probably the extent of their knowledge of the vessel. Nichols (A Voyage for Madmen, etc.) fills in the gaps with this biography of Robert FitzRoy, the Beagle's second captain. In 1828, FitzRoy took command after the first captain went mad and killed himself. Picking up where his predecessor left off charting the waters off South America, FitzRoy captured several natives and brought them back to England so they could be taught the ways of Western civilization. Complications required their immediate return, and it was FitzRoy's request for a traveling companion of equal social status on this hastily planned journey that resulted in Darwin's coming aboard. Nichols, who has taught creative writing at Georgetown and NYU, picks his narrative details well, fleshing out FitzRoy's personality and his shifting relationship with Darwin (though initially friendly, the captain came to violently reject his traveling companion's scientific conclusions). The bulk of the story is devoted to FitzRoy's two missions for the Royal Navy, both of which made him a well-known figure in England. The final chapters trace his eventual downfall, though emphasizing the "dark fate" in the subtitle is rather misleading. Though the author's enthusiasm for his subject can lead to hyperbole, it'll prove hard not to share his fascination with how FitzRoy's naval career inadvertently set off a scientific controversy still flaring to this day. 8 illus. Agent, Sloan Harris. (Oct.)Forecast:Although Nichols's book covers a specific slice of history, it could appeal to science readers with a fondness for travel/adventure yarns. The author plans an eight-city tour.
