Abstract

Genetic, morphological, and behavioral analyses have been used to examine the evolutionary dynamics and phylogeny of the rare Hawaiian Drosophilaspecies, D. silvestris. Critical to understanding the evolution of this species is the examination of the distribution of populations of D. silvestris on the Big Island of Hawaii. Behavioral analysis using mating asymmetries and the Kaneshiro hypothesis as an indicator of ancestral behavioral state has suggested that files from the northern part of the island are ancestral to those on the southern part of the island. Consequently, a sequential pattern of colonization going from north to south is predicted for these flies on the east side of the Island of Hawaii. We have examined this prediction using mitochondrial DNA (mtDNA) restriction site analysis with four-base cutters and DNA sequencing. The resulting mtDNA phylogeny based on 23 phylogenetically informative restriction sites and two phylogenetically informative DNA sequence characters agrees in part with the phylogeny predicted from the behavioral data.
