The Galapagos Islands’ extreme isolation, roughly 1,000 kilometres off the coast of Ecuador, allowed species there to evolve largely independently of mainland pressures, producing the unusual, highly specialised wildlife that caught Charles Darwin’s attention during his 1835 visit aboard HMS Beagle. Darwin’s observations of the islands’ finches, whose beak shapes varied distinctly from island to island depending on available food sources, became a foundational piece of evidence for his later theory of evolution by natural selection.
That isolation also produced species found nowhere else on Earth: the Galapagos giant tortoise, which can live over 150 years and grow to more than 250 kilograms, and marine iguanas, the only lizards on Earth adapted to forage in the ocean, diving to graze on underwater algae before returning to sun themselves on volcanic rock.
An Ecosystem Still Actively Protected
Roughly 97% of the Galapagos’s land area is protected as a national park, and visitor access is tightly regulated, licensed guides, fixed trails, and strict limits on group sizes, specifically to minimise human impact on an ecosystem still considered remarkably intact by global standards. Conservation efforts have included ambitious invasive species eradication programs, removing goats, rats, and other introduced animals that had begun disrupting native species after centuries of human contact.
The islands themselves are volcanic in origin, still geologically active, with Fernandina and Isabela islands among the most volcanically active locations on Earth, new lava fields periodically reshaping the landscape even today.
Painting Volcanic Rock and Endemic Life
The stark volcanic landscape and unusual wildlife of the Galapagos give a watercolourist a genuinely singular subject to capture. We’ve painted that raw, isolated beauty in our own Galapagos Islands Watercolor Print, printed to order on archival paper, a small piece of Ecuador for a wall at home.
Isolated long enough to rewrite an entire scientific theory, the Galapagos Islands remain one of the only places on Earth where evolution is still something you can watch happening.
