A species of bird has slight variations in its beak size and shape. Some individuals with bigger beaks are better at cracking seeds. Some individuals with narrower beaks are better at hunting for bugs. An invasive species is introduced that hunts all of the bug population, wiping out that food source for the birds, so all they are left with is seeds.

Question

In one to two sentences, explain how genetic variation from sexual reproduction can save this species from extinction. Short and original

Answer 1

Thual reproduction, individuals with a wider range of beak sizes and shapes can produce offspring with a greater diversity of traits. This genetic variation may allow some individuals to adapt to the new food source of seeds and survive, ultimately preventing the extinction of the species.
