Darwin's finches are often used to illustrate evolution. evaluate the finch beaks shown in the picture. choose all of the statements that correctly explain the evolution of finch beaks a. as the environment changed the finches grew longer beaks to allow the to get food out of fruits
b. finches with longer beaks settled on the same island with smaller beaked birds. Over time they bred producing medium beaked birds that became more common in the population.
c. there are finches with different types of beaks in the population. during a drought , those with shorter beaks are not able to find sufficient food and die, leaving them unable to reproduce and pass the trait onto offspring
d. a random mutation introduced the shorter thicker beak into the population. however those with thinner longer beaks were better able to get nectar from island's flowers. those with the shorter, thicker beaks were unable to get enough food to survive
E. a disease swept through the island killing many of the insects that were common on the island, leaving the birds who ate insects from the ground staving. the finches that had thicker beaks and could get food from tree bark were able to continue to survive and reproduce, increasing this trait in the population. ​
