Question

A large island has many different types of geography, including a large mountain area in the center. it is broken into a chain of many small islands when the ocean level rises. after the small islands form, the rate of speciation is very high.

a.name three reasons that this area has a high rate of speciation, and explain each in one sentence.

Answer 1

The following are the three reasons why this area has a high rate of speciation:

1. Low population – since it is an island, small random variations affect a significant part of the population.

2. Unique locally trapped populations, each on its own island.

3. Alternative conditions in the varying types of geography, which allows local specializations.
