Abstract
Correction: Evolution of Eye Morphology and Rhodopsin Expression in the Drosophila melanogaster Species Subgroup
Highlights
Compound eyes are composed of subunits called ommatidia and the great diversity of eye sizes and shapes among insects [1] is mainly the result of evolutionary changes in either ommatidia number (1 in some ant workers to 30000 in dragonflies) or ommatidia diameter (5–50 mm) [1,2,3]
We found that the D. mauritiana strains TAM16 and MAV1 have larger eyes than all D. melanogaster and D. simulans strains surveyed (Figure 1B, Table S1; one-way ANOVA: F(17,597) = 168.37, p,0.0001)
We found that D. melanogaster M36 and OreR have the smallest eyes among the strains surveyed, the African strain of this species (Zi372) exhibits eye areas comparable to those of the D. simulans strains (Figure 1B, Table S1; D. melanogaster females of M36 and OreR are not significantly different)
Summary
Compound eyes are composed of subunits called ommatidia and the great diversity of eye sizes and shapes among insects [1] is mainly the result of evolutionary changes in either ommatidia number (1 in some ant workers to 30000 in dragonflies) or ommatidia diameter (5–50 mm) [1,2,3]. These two parameters significantly influence the optical properties of the compound eye. Dorsal-frontal locally restricted acute zones with large ommatidia and reduced interommatidial angles that produce increased resolution to optimise the pursuit and capturing of prey or mating partners have evolved in several insects [9,10,11,12,13]
