Where did Charles Darwin observe different types of animals which helped him later develop his theory of natural selection?

• A. Madagascar
• B. Canary Islands
• C. Galapagos Islands
• D. Fiji

Answer: (C)

The main idea is how variation among related animals in different environments can lead to evolution through natural selection. On his voyage, Darwin noticed that island groups hosted related species that looked different and seemed adapted to their local foods and climates. The classic example is the finches of the Galapagos, where beak shapes ranged from stout to slender, each suited to a specific food source like seeds, insects, or cactus. He also observed differences among tortoises from different islands, with shells and neck lengths that matched the plants available there. These patterns suggested that species aren’t fixed; small inherited differences can give some individuals a reproductive edge in a particular environment, and over many generations these differences can become new species.

Other places mentioned have unique wildlife, but the particularly influential observations that helped shape the theory of natural selection came from the Galapagos Islands, where closely related species varied in direct relation to their island environments.
