Answer :
1. Initially, when finches colonized Santa Maria and San Cristobal islands, it is likely that G. fuliginosa had beak sizes similar to those of finches on Los Hermanos island, while G. fortis probably had deeper beaks similar to finches on Daphne island.
2. The presence of significant overlap in beak size would have led to interspecific competition for food resources.
3. Natural selection favored phenotypes that competed less for food, leading to changes in beak sizes.
4. In G. fortis finches, individuals with deeper beaks were selected for due to their advantages in accessing specific food sources.
5. In G. fuliginosa finches, individuals with shallower beaks were selected for, possibly due to their ability to access different food resources.
6. Both species experienced directional selection, resulting in character displacement in beak size.
7. The character displacement in beak size is adaptive for both populations as it helps reduce interspecific competition for limited food resources.
Character displacement in beak sizes occurred in the finch populations of Santa Maria and San Cristobal islands. When these finches initially colonized the islands, G. fuliginosa had beak sizes resembling those of finches on Los Hermanos island, while G. fortis had deeper beaks akin to finches on Daphne island. This indicates that there was beak size variation among the different islands.
The substantial overlap in beak size between the two species likely resulted in competition for food resources. This competition exerted pressure on the finches, and as a result of natural selection, phenotypes that competed less for food were favored.
In G. fortis, individuals with deeper beaks were selected for, while in G. fuliginosa, individuals with shallower beaks were favored by natural selection. This led to distinct beak size variations in each species.
The selective pressure induced directional selection for beak size in both species. Finches with beak sizes differing from the other species gained a competitive advantage and were more successful in acquiring food resources. Consequently, character displacement emerged, causing the beak sizes of the two species to diverge and reduce competition.
In summary, character displacement proves advantageous for both finch populations as it diminishes interspecific competition. Through the evolution of distinct beak sizes, each species can occupy a slightly different ecological niche and access specific food sources, thereby reducing resource competition.
In conclusion, the process of character displacement in the finch populations on Santa Maria and San Cristobal islands resulted from directional selection, promoting distinct beak sizes for each species. This adaptive trait reduces interspecific competition and facilitates coexistence among the finches in their respective niches.
