Charles Darwin’s Trip to the Galapagos.

While Charles Darwin did not discover the Galapagos Islands, he is the name most associated with their history and recognition.
For it was Charles Darwin, a young naturalist, who came to the Islands, observed the plant, marine, bird and animal life and designed the intellectual premise known as natural selection or survival of the fittest.
His thoughtful interpretation of what he saw and recorded changed human thought and understanding of the world around us forever.
He saw continuity and coherency despite the diversity on each island and was able to merge these observations into a cogent scientific process that explains how life on earth evolved.
Darwin visited the Galapagos Islands in 1835.
Of his five-year voyage, he spent only five weeks in the Galapagos Archipelago and only about 19 days ashore, on the islands we now call San Cristobal, Isabela, Floreana and Santiago.
He observed, “the natural history of this archipelago is very remarkable; it seems to be a little world within itself.” Indeed, that statement is equally true 1½ centuries later.
During his explorations, Darwin noticed that while each island often had the same types of bird, animal and plant life, there were subtle differences in each of them.
He saw strange animals, unlike elsewhere in the world, but obvious familial relationships as well.
He wrote, “Several of the islands possess their own species of tortoise, mockingbird, finches and numerous plants, those species having the same general habits, occupying analogous situations, and obviously filling the same place in the natural economy of this archipelago, that strikes me with wonder.”

For example, there were more than 15 separate species of finches at that time and Darwin determined to make sense of that fact.
He concluded that each was closely related to the mainland finch, but had adapted to its new surroundings, undergoing subtle but distinct changes to allow them to survive and procreate in their individual environment.
