What did Darwin collect on the galapagos islands?

During his visit to the Galápagos Islands, Charles Darwin collected a variety of specimens, including numerous plant species, insects, and animals such as birds, tortoises, and marine iguanas. He famously gathered finches, which later contributed to his theories on natural selection due to their distinct adaptations to different environments across the islands. These collections provided crucial evidence for his ideas about evolution and the diversity of life.
