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. In one to two sentences, explain how genetic variation from sexual reproduction can save this species from extinction..
With genetic variation from sexual reproduction, some individuals with bigger beaks that are better at cracking seeds will have a better chance of survival and reproduction, leading to the passing on of their advantageous traits to future generations. This increased variation in beak size and shape can potentially ensure the survival of the species by allowing individuals to adapt to the new food source.
