The ancestor to the Hawaiian crickets in the genus Laupala originally colonized the oldest of the island in the Hawaiian archipelago
As new islands were formed, individuals from the older island would colonize the younger island. Because members of this genus are flightless, these migration events were likely to be extremely rare and would include a small number of migrants. Differ-ences in allele frequencies in this genus are likely due to:
a. population bottleneck.
b. founder event.
c. drift.
d. A and C.
e. B and C.
