There are two major hypotheses for the evolution of winged flight in insects: wings originated either in tree-living, gliding hexapods as lateral body extensions of the body wall, or wings derived from gills of aquatic forms. Gliding is widespread among vertebrates that live in trees, but to date has not been identified in phylogenetically basal hexapods.
Here we show that arboreal jumping bristletails, a basal hexapod lineage lacking wings, glide to tree trunks in 90% of falls, and that their tail appendages influence aerial manoeuvres and gliding success rates.
This discovery lends support to hypothesized terrestrial origins for insect flight.
