Darwin and the Beagle: The Book That Changed Biology Forever

In 1831, a 22-year-old who had dropped out of medicine and was drifting toward becoming a country parson boarded a Royal Navy survey ship called HMS Beagle for what he thought would be a two-year trip. It lasted five years. Charles Darwin came home with thousands of specimens, notebooks full of observations, and a nagging question about why similar species appeared in slightly different forms on different islands. He spent the next twenty years developing the answer, and in November 1859 he published On the Origin of Species. The 1st print run of 1,200 and fifty copies sold out on the day of publication.
