Out of the 13 types of finches collected by Darwin from Galapagos:

Explanation

During his voyage on the Beagle, Charles Darwin collected 13 species of finches from the Galapagos Islands. A crucial observation he made was that some of these finch species were unique to individual islands. This indicated that these finches had evolved independently on each island, adapting to their specific environments and developing distinct characteristics. This finding supported Darwin's theory of evolution through natural selection, suggesting that these finches had evolved from a common ancestor but had diverged into distinct species due to geographic isolation.Option A is incorrect as not all finch species were unique to individual islands. Option B is partially correct but does not address the core observation of species uniqueness. Option D is incorrect as it overstates the uniqueness of the majority of species.
