Few creationists are familiar with the biogeographic evidence for evolution, yet it is one of the strongest pieces of evidence for evolution.
Why do species on islands resemble species on the nearest mainland, even if there is a vast difference in environmental conditions between the island and the mainland? If a creator was independently creating species, why would he create species on islands that are similar to those on the nearest continent or mainland? The species found on islands such as the Galapagos, while distinct from the species of the nearest mainland, resemble them more closely than they resemble the species of other islands with more similar environmental conditions, indicating that the species on the islands descended and evolved from the species on the nearest mainland.
This is what Darwin had to say on the subject:
"The naturalist, looking at the inhabitants of these volcanic islands in the Pacific, distant several hundred miles from the continent,feels that he is standing on American land. Why should this be so? Why should the species which are supposed to have been created in the Galapagos Archipelago, and nowhere else, bear so plainly the stamp of affinity to those created in America?There is nothing in the conditions of life, in the geological nature of the islands, in their height or climate, or in the proportions in which the several classes are associated together, which closely resemble the conditions of the South American coast: in fact, there is a considerable dissimilarity in all these respects.... Facts such as these admit of no sort of explanation on the ordinary view of independent creation; whereas on the view here maintained, it is obvious that the Galapagos Islands would be likely to receive colonists from America, whether by occasional means of transport or (though I do not believe in this doctrine) by formerly continuous land ...such colonists would be liable to modification,—the principle of inheritance still betraying their original birthplace."
Creationists cannot explain away this evidence. They just pretend it doesn't exist.
