These finches live on the Galapagos Islands, about 1000 kilometers (621 miles) off the coast of South America. Darwin also observed that all the species on the Galapagos Islands resembled a finch species living on the South American continent. What type of evidence did Darwin use in this case to support his theory of evolution? A biogeography B fossil record C molecular biology D comparative embryology 2. The forelimbs of birds, reptiles, and mammals contain the same kinds of bones that develop in the same way. Such structures are called homologous structures.
