Darwin's Voyage on the Beagle

Darwin's Beagle Voyage

Galapagos Islands

• Visited in 1835, a pivotal moment in Darwin's understanding of evolution
• Observed distinct species of tortoises, mockingbirds, and finches that varied between islands
• Realized that species on different islands were similar but not identical, sparking thoughts on adaptation and speciation

Geological Observations

• Darwin collected numerous geological specimens and made observations on volcanic and coral reef formations
• Recognized the importance of uplift and subsidence in shaping the Earth's surface
• Noted the similarity between South American and Galapagos geological formations, supporting the idea of continental drift

Species Collection

• Collected over 450 species of plants and animals, including many new species
• Preserved specimens using various methods, including skinning, stuffing, and pickling
• Sent many specimens back to England for further study and classification

Fossil Discoveries

• Discovered fossils of extinct species, including giant armadillos and ground sloths
• Realized that these fossils were related to modern species, but were more primitive
• Recognized the significance of fossil record in understanding Earth's history and evolutionary processes

Voyage Route And Navigation

• HMS Beagle set sail from Plymouth, England in 1831
• Voyage route included South America, Galapagos Islands, Tahiti, New Zealand, and Cape of Good Hope
• Navigation was challenging, with Captain Robert FitzRoy using celestial observations and chronometers to determine the ship's position
