Question

The changes in shape of bird beaks [Darwin’s Finches- as shown in the picture] is an example for

• A. variation and natural selection
• B. Geographic isolation
• C. diverse food habits
• D. All of the above

Answer 1

The correct option is D

All of the above

Darwin's finches are a group of about fifteen species of passerine birds. These birds, although nearly identical in all other ways to mainland finches, had different beaks. Their beaks had adapted to the type of food they ate in order to fill different niches on the Galapagos Islands. Their isolation on the islands over long periods of time made them undergo speciation.
