Dual evolutionary origin of insect wings supported by an investigation of the abdominal wing serial homologs in Tribolium.

ABSTRACT: The origin of insect wings is still a highly debated mystery in biology, despite the importance of this evolutionary innovation. There are currently two prominent, but contrasting wing origin hypotheses (the tergal origin hypothesis and the pleural origin hypothesis). Through studies in the Tribolium beetle, we have previously obtained functional evidence supporting a third hypothesis, the dual origin hypothesis. Although this hypothesis can potentially unify the two competing hypotheses, it requires further testing from various fields. Here, we investigated the genetic regulation of the tissues serially homologous to wings in the abdomen, outside of the appendage-bearing segments, in Tribolium We found that the formation of ectopic wings in the abdomen upon homeotic transfor
