Evolution Question

Three Pacific islands, X, Y and Z, appeared approximately 5 million years ago as a result of volcanic activity. Islands X and Y have about the same area, and island Z is about 10 times larger than X and Y combined. X is closer to the nearest mainland than either Y or Z, which are both approximately equidistant from the mainland. Assume that each island was colonized independently of the others. How would you expect the natural faunas and floras of the three islands to differ? Explain. Describe the data you would need to collect to test your predictions. Thanks
