Considering that most of the Hawaiian islands (like other isolated
island groups) have never even had a land connection to each other
(except for Maui Nui, and Molokai-Oahu for a time about 2 million
years ago), let alone to a continent, that's hardly surprising.  The
only ones who consider vicariance for the origin of the Hawaiian
biota are those who believe in the continent of Mu.
