Answer:
The type of selection that we can predict over the course of multiple generations of these birds is the disruptive selection.
Step-by-step explanation:
In nature specific adaptations (to different environments and foods, for example) are more beneficial to a species in order to developed and perform a certain way to thrive in their environment. The disruptive selection is a model of natural selection that doesn’t select the average individual in a population, or in this case: the birds with the intermediate beak size thus they are the ones most likely to disappear.
