Question

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? 1. Scientists in search of ongoing speciation events are more likely to find them here than on the other six large islands. 2. Its species should be more closely related to those of nearer islands than to those of farther islands. 3. It should have a rich fossil record of terrestrial organisms. 4. It should have species that are not found anywhere else on Earth. 5. On average, it should have fewer species per unit surface area than the other six islands.

Answer 1

Answer:

What should be TRUE of the island of Hawaii :

• Scientists in search of ongoing speciation events are more likely to find them here than on the other six large islands.

• Its species should be more closely related to those of nearer islands than to those of farther islands.

• It should have a rich fossil record of terrestrial organisms.

Explanation:

In cases of geographic isolation, and subsequent speciation, produced by dispersal and colonization phenomena we can find the island of Hawaii. Adaptation to these environments can be the trigger for divergence. The large number of species in this archipelago, more than 500, seems to have emerged  through migration and diversification. Many of these are endemic to a nearby island, and the subsequent evolutionary divergence.

The volcanic islands, which have never been in contact with the continent, are especially rich in endemic species; the species that inhabit them are descendants of those who arrived in times past and were able to adapt.

Almost ninety years ago, in the south of the island of Hawaii, they revealed some bones that turned out to be the first bird fossils discovered in the archipelago. The bones were under a flow of prehistoric lava and on a bed of volcanic ash.

In short, the Island of Hawaii is of great interest to scientists and there are always new developments buried years ago by volcanic activity.
