Darwin’s Delay

Few events inspire more speculation than long and unexplained pauses in the activities of famous people. Rossini crowned a brilliant operatic career with William Tell and then wrote almost nothing for the next thirty-five years. Dorothy Sayers abandoned Lord Peter Wimsey at the height of his popularity and turned instead to God. Charles Darwin developed a radical theory of evolution in 1838 and published it twenty-one years later only because A. R. Wallace was about to scoop him.
