What characteristics of the Galapagos islands were particularly important for Darwin?

Answer 1

The isolationism of the islands was important. He knew that things had been untouched there so everything would react without interference.

Answer 2

The unique biodiversity and isolated ecosystems found on the Galapagos Islands were important for Darwin's theory of evolution by natural selection. He observed distinct species on each island that had adapted to their specific environment, which helped him develop his ideas on how species evolve over time. The islands' geographical isolation also allowed for the evolution of new species in a relatively short period, providing valuable evidence for Darwin's theory.
