Charles Robert Darwin enters the world in a Shropshire market town, the son of a wealthy physician. He will spend decades observing barnacles, finches, and pigeons before publishing 'On the Origin of Species' in 1859, a work that upends humanity's understanding of its own origins and remains one of science's most consequential books.
Darwin's birth on February 12, 1809 shares its date with Abraham Lincoln's, born the same day in a Kentucky log cabin — a coincidence that biographers and historians have delighted in for over a century, since the two men, an ocean apart, would each unsettle deeply held assumptions about hierarchy and human nature.
Darwin was an unlikely revolutionary. He struggled at Edinburgh medical school, found dissection unbearable, and drifted toward the clergy before his father arranged a berth on HMS Beagle. The five-year voyage that followed, especially his stop in the Galápagos, supplied the observations that gestated for two decades before he dared publish them, reportedly spurred into print only when Alfred Russel Wallace arrived at similar conclusions independently.
Darwin delayed publishing Origin of Species for so long partly out of dread of the backlash, confiding to a friend that revealing his theory felt 'like confessing a murder.' When it finally appeared, it sold out its first printing of 1,250 copies in a single day.
