Gene flow between species influences evolution in Darwin's finches The cactus finch (Geospiza scandens) is slightly larger than the medium ground finch (G. fortis), has a more pointed beak and is specialized to feed on cactus. Here we report the results of a combined ecological and genomic study of Darwin's finches that documents hybrid speciation in the wild from its inception to the development of reproductive isolation.

Describe TWO major differences between Lamarck's and Darwin's explanations of how evolution works. They were studying . Since these slight variations are passed down from one generation to the next, the brood of a small beak and a medium beak would be likely to have intermediate beaks, equipment that would sometimes differ from their parents' not by one or two tenths of a millimeter but by whole millimeters, maybe by many millimeters.
