The four birds shown in Figure A, B, C, and D are all found on one island environment. A group of biologists relocate half of the population of the birds resembling the bird in figure A are relocated to a new environment, where food sources are different than those present in their current environment. The half of the population of birds left behind on the original island continues to grow and reproduce. What changes might a scientist expect to see in the species? a. The species would adapt over time and would become extinct.
b. The species would not adapt over time and would become extinct.
c. The species would not adapt over time and would begin displaying adaptations in their beaks to allow them to consume a new food source.
d. The species would adapt over time and would begin displaying adaptations in their beaks to allow them to consume a new food source.
