Answer:
The population of <em>G. fortis</em> will face a significant reduction or will be eliminated in the long run, while, in presence of large and small seeds, natural selection will favor <em>G. magnirostris</em> and Big Birds. Therefore, they will be more likely to survive.
Explanation:
One of the most important aspects of Natural Selection, proposed by Charles Darwin, states that particular variations in an individual will provide an advantage for their survival.
In this case, as a result of a prolonged drought, some species of birds will face challenges in regard to finding food and, therefore, survival.
Individuals of the species <em>G. magnirostris </em>possess two great advantages:
- They eat large seeds; which means there is no competition as the other species have a preference for small seeds.
- They can outcompete all other finches.
On the other hand, there is a competition and a struggle for survival between two groups: the individuals belonging to the species <em>G. fortis</em> and the Big Birds. However, Big Birds possess one strong advantage: they are bigger, stronger birds that can easily outcompete <em>G. fortis</em> individuals.
Therefore, <em>G. fortis</em> birds would be eliminated from the population due to their smaller size and food preference, not to mention the high competition they face; while <em>G. magnirostris</em> and Big Birds will be 'selected' and favored by natural selection resulting in their survival in Daphne.
