In the 1950s, a British physician and amateur lepidopterist named H. B. D. Kettlewell went into the English woods to catch "evolution in action" among the now-famous Peppered Moths. His work became "Darwin's missing evidence," an evolutionary experiment as influential as any in the last century. Compellingly told, Of Moths and Men reveals Kettlewell to be a deluded scientist, a man tyrannized by his mentor, the powerful E. B. Ford, an imperious, eccentric Oxford don, a Darwinian zealot determined to crush all enemies in his path. In a revelatory, controversial work that will be debated for years to come, Judith Hooper uncovers the intellectual rivalries, petty jealousies, and faulty science behind one of the most famous experiments—and myths—in the history of evolutionary biology.
