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.

Answer 1

Genetic variation from sexual reproduction allows for the possibility of some individuals having traits that make them more adept at cracking seeds, giving them a better chance of surviving and reproducing despite the loss of their primary food source. By passing on these advantageous traits to their offspring, the population may be able to adapt to the new food source and avoid extinction.
