The famous voyage of the Beagle took Charles Darwin around the world as an unpaid companion to captain Robert Fitzroy, allowing him to explore some of the Galapagos’ most isolated locations.Darwin knew almost intuitively that there was something special about the Galapagos Islands as evidenced by an observation he wrote about evolution prior to arriving: “if there is the slightest foundation for it, the zoology of the Galapagos will be well worth examining.

While on Santiago Island, it was brought to his attention the great differences among giant tortoises that existed from island to island, and on Floreana, he found the mockingbirds differed to those he had observed on San Cristobal.

 

These were the observations that became the foundation for his theory of evolution, and that led to the publication in 1859 of On the Origin of Species, the book that eventually paved the way for the acceptance of evolution.
