The different Galapagos finch species are an example of:
artificial selection. random evolution. disruptive selection. adaptive radiation.
The different Galapagos finch species are an example of adaptive radiation. This process occurs when a single ancestral species rapidly diversifies into a variety of forms to adapt to different environments and ecological niches. In the case of the Galapagos finches, they evolved distinct beak shapes and sizes to exploit different food sources available on the islands.
