After the drought of 1977, researchers hypothesized that on the Galápagos Island Daphne Major, medium ground finches with large, deep beaks survived better than those with smaller beaks because they could more easily crack and eat the tough Tribulus cistoides fruits. A tourist company sets up reliable feeding stations with a variety of bird seeds (different types and sizes) so that tourists can get a better look at the finches. Which of these events is now most likely to occur to finch beaks on this island?

#Unit 11. Evolution and Behavior
  1. evolution of yet larger, deeper beaks over time, until all birds have relatively large, deep beaks

  2. evolution of smaller, pointier beaks over time, until all birds have relatively small, pointy beaks

  3. increased variation in beak size and shape over time

  4. no change in beak size and shape over time
