Due to the _ of the first small population on one of the island's, the populations _ could have been different from their continental fruit fly ancestors.

answer:

There is a hypothesis that proposes that the different Hawaiian drosophilids diverged from a sole common ancestor that once colonized the Hawaiian Islands, then known as the Hawaiian Scaptomyza who subsequently moved back to different continents.

However, by newly determining the DNA sequence information of 11 kinds of non-Hawaiian Scaptomyza species and analysing it along with existing sequence information, the researchers reconstructed the phylogeny. This study theorizes that Hawaiian drosophilids had plural continental ancestors that independently migrated to Hawaii at different times.
