Why would a finch population that lives on an island have a higher rate of speciation that a finch population that lived in a large forest in north America?

A finch population on an island is more isolated than Êa finch population in a large forest. ÊThe gene pool of the island population would be more limited than the genetic possibilities of the finch population in the forest. ÊThe island finches would be more likely to pass on specialized genes than the forest finches.

the island finches have more spatial isolation

the island finches have more geographical isolation
