Question

Which of the following species of finch would be most likely to survive if the weather on the Galapagos Islands gradually changed, and the seeds available to the finches became larger with heavier coverings?

A) Small Ground Finch
B) Medium Ground Finch
C) Large Ground Finch
D) Sharp-beaked Ground Finch

Answer 1

The Large Ground Finch would be most likely to survive if the seeds on the Galapagos Islands became larger with heavier coverings.

Step-by-step explanation:

The species of finch that would be most likely to survive if the weather on the Galapagos Islands gradually changed and the seeds available to the finches became larger with heavier coverings is the Large Ground Finch (C).

In a drought that occurred on the Galapagos Islands, many of the small-beaked finches died because they could not crack open and eat the larger seeds. However, the larger-beaked finches were able to crack and eat seeds of all sizes, allowing them to survive and reproduce.

This demonstrates how natural selection favors individuals with traits that are best suited to their environment. In this case, the Large Ground Finch with its larger beak is better able to adapt to the changing seed availability.
