TL;DR: Genomic consequences of recent, adaptive song loss in a Hawaiian population of field crickets suggest that the early stages of evolutionary adaptation to extreme pressures can be accompanied by greater genomic and phenotypic disruption than previously appreciated, and highlight how abrupt adaptation might involve suites of traits that arise through pleiotropy or genomic hitchhiking.

TL;DR: In this article, a genomic study on Hawaiian crickets from different island populations finds evidence of parallel adaptation to the same lethal parasitoid in spite of strong ongoing gene flow, indicating that it could be less constrained than previously appreciated.

TL;DR: Host-parasite interactions are predicted to drive the evolution of defences and counter-defences, but the ability of either partner to adapt depends on new and advantageous traits arising.

TL;DR: Investigation of a Hawaiian field cricket in which an X-linked genotype (flatwing) feminizes males' wings and eliminates their ability to produce sexually selected songs finds no evidence of feminized gene expression in males, and suggests sex-limited phenotypic expression offers only partial resolution to intralocus sexual conflict.

TL;DR: The role of vestigial behaviour in evolution has been examined in this paper, where the authors identify important areas for future research to help determine whether vestigual behaviours essentially represent a form of evolutionary lag, or whether they have more meaningful evolutionary consequences distinct from those of other vestigenial and behavioural traits.
