All your fly base are belong to us
Over one hundred of these Drosophila species are members of the 'picture wing group'. The figure I showed in class just depicts the hypothesized dispersal events necessary to create the 112 members of the picture wing group. Although the picture wing species are quite distinct from each other in morphology, pigmentation, and behavior it is now known that this explosive adaptive radiation occurred with relatively little change in DNA sequence. These factors make the Hawaiian Drosophila an important model system for analysis of evolutionary processes at the species level.
