Answer: This can be useful site to study the diversity of organisms.
Explanation:
The founder effect is the known phenomena proposed by Ernst Meyer. It occurs when a small number of organisms leave the larger population. The genetic variation will be lost when a new population is established by the small population. Due to lack of genetic variation the new population becomes phenotypically and genotypically different from the parent population. This process lead to speciation.
The islands are the regions where few organisms can be found, those have migrated from the native land. Thus the study of diversity of these organisms will become simple.
