Question

A large number of finch species share similar habits and characteristics with the exception of beak shape. Finches with large, tough beaks eat large seeds. Finches with small beaks cannot crack the large seeds. During drought conditions, only large seeds are available as a food source. Which of the following would be the result of natural selection for extended periods of drought?A. Finch species with large beaks would not survive to reproduce and continue the traitB. Finch species with medium-sized beaks would not survive to reproduce and continue the traitC. Finch species with small beaks would not survive to reproduce and continue the trait

Answer 1

If the finches with small beaks cannot crack the large seeds, it is an evolutionary disadvantage. So, following natural selection rules, those birds probably would die because they would spend long times without eating (as there are no seeds that they are able to crack). If all of them comes to die, this trait could be lost. Therefore, the correct answer is C. Finch species with small beaks would not survive to reproduce and continue the trait.
