Question

what have scientists learned about the finch birds on the galapagos islands?○ the birds beaks have stayed the same.○ different birds were the result of selective breading.○ the birds beaks changed over time.○ there are no birds on the galapagos islands.

Explanation:

Studies of Galápagos finches show their beak shapes and sizes have evolved over time in response to changes in food availability, a key example of natural selection. The other options are incorrect: beaks have not stayed the same, the birds evolved via natural selection not selective breeding (which is human-directed), and there are clearly finches on the Galápagos.

Answer:

○ The birds' beaks changed over time.
