Galapagos Islands
Chapter 4. This island group is famous as the site at which Charles Darwin collected evidence for evolution of species. Because the islands are so isolated, they were free of human inhabitants until relatively recently. Most of the animals never developed a fear of humans. It is a popular ecotourist destination today because of its biodiversity and historic scientific importance. Questions:
1. Approximately how many islands can you see in this group? There are about ten islands clustered in the main group, with a couple of other minor outlying islands more to the north.
2. What country claims the Galapagos? Ecuador
3. If you zoom in on the northern end of Isla Isabela, the largest island, you'll see several round features. What are these? They are the calderas of the shield volcanoes that formed the island.
4. How far is it from the Galapagos to the mainland of South America? Why is this important for Darwin’s studies? Approximately 690 miles. This distance is far enough to isolate the Galapagos from other mainland species, allowing animals there to evolve separately.
Great Barrier Reef, Australia
Chapter 5. Corals are an outstanding example of symbiosis, in which a coral polyp (an animal) and an alga (which photosynthesizes) live together and benefit each other. Together, these partners build some of the largest structures created by any living organism. The Great Barrier Reef is the longest coral reef in the world. Coral reefs are renowned for the diversity, beauty, and the economic importance of the fish and other organisms that shelter or reproduce in the complex niches and crevices of a reef. More than 1,500 species of fish, shrimp, and other organisms find shelter and reproduce in the reef's crevices.
