Implication

Phylogenomic analysis reveals evolutionary transitions and phenotypic adaptations in semi-aquatic bugs, highlighting how colonizing the water-air interface promoted lineage diversification.

Key Points

To resolve the phylogeny of semi-aquatic bugs (Gerromorpha) using transcriptomics and determine how key innovations drove subsequent phenotypic adaptation and species diversification.
Reconstructed the phylogeny of Gerromorpha using whole-transcriptome sequencing datasets across N=97 species calibrated with fossil records.
Performed ancestral state reconstruction on critical phenotypic traits, including fluid locomotion, dispersal ability, transitions to saline waters, and sexual dimorphism.
Resolved long-standing taxonomic inconsistencies within Gerromorpha and identified strongly supported, previously unrecognized relationships among major taxa.
Showed that the primary adaptation enabling bugs to occupy the water-air interface facilitated multiple independent expansions into novel adaptive zones, from freshwater ponds to marine environments.
