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.
please help

Answer 1

Genetic variation from sexual reproduction can save this species from extinction by providing a range of beak sizes and shapes within the population, thus increasing the likelihood that some individuals have traits—like larger beaks—that are advantageous for surviving the new conditions by effectively cracking seeds, allowing them to feed, survive, and pass on their genes to future generations. Over time, this could lead to natural selection favoring individuals with larger beaks, enabling the species to adapt to the loss of bugs as a food source.
