I believe the reason for this would be geographical evolution. Different ecosystems cause the finches to evolve differently over time. Also, since the finches on the Galápagos Islands are closer to the one in South America, it is likely that finches from there (South America) could have moved to the islands, contributing to the evolutionary process.
I don't know the answer but try reading this:

Good Luck!!
Could you provide the sentence
Explanation:
Colonization, or colonisation refers to large-scale population movements where the migrants maintain strong links with their or their ancestors' former country, gaining significant privileges over other inhabitants of the territory by such links. When colonization takes place under the protection of colonial structures, it may be termed settler colonialism. This often involves the settlers dispossessing indigenous inhabitants, or instituting legal and other structures which systematically disadvantage them.
In its basic sense, colonization can be defined as the process of establishing foreign control over target territories or people for the purpose of cultivation, often through establishing colonies and possibly by settling them.
In colonies established by Western European countries in the Americas, Australia and New Zealand, settlers (supplemented by Central European, Eastern European, Asian and African people) eventually formed a large majority of the population after killing, assimilating or driving away indigenous peoples.
