Some individuals with narrow beaks are better at hunting for bugs and invasive species is introduced that hunts all of the bug population wiping out that food source for all the birds so all they are left with the seeds in one to two sentences explain how genetic variation from sexual reproduction can save the species from extinction

Answer 1

With genetic variation from sexual reproduction, some birds with bigger beaks may have the ability to adapt and crack the seeds effectively, ensuring survival when their primary food source is wiped out by the invasive species.
