allopatric speciation
The Galapagos finches only exist on the islands and inspired Charles Darwin. They implied that evolution occurs through natural selection.
Animals living in the Galapagos Islands, such as the finches studied by Charles Darwin, provide evidence for evolution through natural selection. These animals have adapted to their unique environments over time, leading to the development of different species with distinct characteristics. By observing these variations in species, scientists can better understand how evolution occurs and how species change over generations.
Genetic isolation. This occurs when members of species that also occur on mainland areas begin to evolve slightly different habits and appearances.
True
think Darwin's finches and galapagos tortoises... speciation that occurs when biological populations of the same species become isolated due to geographical changes such as mountain building or social changes such as emigration. The isolated populations then undergo genotypic and/or phenotypic divergence as: (a) they become subjected to different selective pressures, (b) they independently undergo genetic drift, and (c) different mutations arise in the populations' gene pools.[1]

Sympatric Speciation
Rapid speciation occurs as populations adapt to the environment. (Novanet)
