Finches on the Galapagos islands exhibit remarkable variation in the shape of their beaks. What best explains this variation?Multiple choice question.Differences in their feeding habitsSubtle differences in the climate of different Galapagos islandsDifferences in their predatorsDifferences in their breeding strategies

What did Darwin observe about the finches he collected from the Galápagos Islands?a. They all had identical beak shapesb. They were unrelated to each otherc. They evolved from South American speciesd. They had different beak shapes suited to their diet

After the drought of 1977, researchers hypothesised 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?Question 4Select one:a.evolution of yet larger, deeper beaks over time, until all birds have relatively large, deep beaksb.evolution of smaller, pointier beaks over time, until all birds have relatively small, pointy beaksc.increased variation in beak size and shape over timed.no change in beak size and shape over timeClear my choice

What is the preferred food of the Galápagos medium ground finch?Multiple choice question.Small, tender seedsLarge, dry seedsMedium seeds
