When on board H.M.S “Beagle,” together naturalist, i was much struck with specific facts in the distribution of the organic us inhabiting south America, and also in the geological relationships of the present to past inhabitants of the continent. This facts, as will be checked out in the latter chapters of this volume, seemed to throw part light ~ above the origin of species—that an enig of mysteries, together it has actually been referred to as by among our best philosophers.

Making sense of What Is already Known

The story that Semmelweis is just one of a scientist confronting a secret and systematically walking out and gathering brand-new data that aided him settle the mystery. The story of Darwin is really different. On the origin of Species, Darwin’s four-hundred-plus-page “abstract,” is among the best-argued functions in the background of science. He provides a powerful case for, what us shall see, are two huge theories. Although that was wonderful field biologist and also geologist, and also although his experiences on the Beagle were clearly formative, the proof he presented in top top the origin of types was no original; nor did the contain cutting-edge discoveries. Darwin’s genius was seeing, I would say, explaining, well-known facts in original and insightful ways.

The history of science is complete of examples where the revolutionary breakthrough comes, no in the laboratory, yet in the theorist’s study. This is solid surprising, since when you room trying to make sense of the myriad of facts and results the compose any type of of the organic sciences, the level of generality and also abstraction required for the grand overarching theories will certainly seldom, if ever, come from one nicely designed experiment. Darwin had the ability to articulate general ethics that have unified biological for more than a century and a half. And most remarkably, fit perfect with organic discoveries that Darwin himself might never have imagined.
