The map below shows is land chains in the South Pacific. In chains like the one shown below, speciation among animal populations can occur.
Main island
Other islands

Which of the following best explains what favors speciation in these situations?.
Predators on the main island can easily migrate to follow the populations to the other islands.
Lack of disease on the other islands enables the populations to grow and change without limit.
The climatic conditions of the islands allow the populations to breed all year and produce several generations.
The physical separation of the islands limits gene flow and interbreeding between the populations.
