According to the theory of seafloor spreading, oceanic islands, such as the Hawaiian Islands, form as oceanic crustal plates move over a stationary "hot spot" in the mantle. Currently, the big island of Hawaii is thought to be over a hot spot, which is why it is the only one of the seven large islands that has active volcanoes. What should be true of the island of Hawaii?
I. Scientists in search of ongoing speciation events are more likely to find them here than on the other six large islands.
II. Its species should be more closely related to those of nearer islands than to those of further islands.
III. It should have a rich fossil record of terrestrial organisms.
IV. It should have species that are not found anywhere else on Earth.
V. On average, it should have fewer species per-unit surface area than the other six islands.
