Question

Darwin visited the Galapagos Islands while on a journey aboard the Beagle. What observation led Darwin to start thinking about evolution?

Answer 1

During the long voyage Darwin made many observations that helped form his theory for evolution. He visited tropical rain forests and other new habitats where he saw many plants and animals he had never seen before. This impressed him with a great diversity of life. He visited rock ledges that had clearly once been beaches that had gradually built up over time.
