Study Notes
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
