BACKGROUND The endemic Hawaiian drosophilids, a unique group that are remarkable for their diversity and rapid proliferation, provide a model for analysis of the process of insular speciation. Founder events and accompanying random drift, together with shifts in sexual selection, appear to explain the dramatic divergence in male morphology and mating(More)
Nucleotide sequence analysis has demonstrated that interspecific size variation in the YP2 yolk protein among HawaiianDrosophila is due to in-frame insertions and deletions in two repetitive segments of the coding region of the Yp2 gene. Sequence comparisons of the complex repetitive region close to the 5′ end of this gene across 34 endemic Hawaiian taxa(More)
