­­­Darwin studied which bird species on the Galapagos Islands?

The correct answer is: Finch

• Darwin's finches from the Galápagos archipelago have historic importance in the field of evolutionary biology as they provided some of the fundamental insights into processes of natural selection and adaptive radiation.
• However, the Galapagos finches helped Darwin solidify his idea of natural selection. The favorable adaptations of Darwin's Finches' beaks were selected over generations until they all branched out to make new species. These birds, although nearly identical in all other ways to mainland finches, had different beaks.
