Language diversity among Pacific islands will be positively associated with large land area, low distance from closest continent, and duration of human settlement (959).


Determined by fitness of models measured by Akaike Information Criterion (AIC). Variables in other models include rainfall, absolute latitude, mean growing season, rainfall, number of ecoregions, continental dust fall, tephra, and island type. Land area on its own maintained a significant correlation to linguistic diversity (see other hypothesis).
