Sexually antagonistic pleiotropy involving frequency-dependent traits like mating display maintains linkage blocks like inversions as balanced polymorphisms in simulation, and may explain common inversion polymorphisms maintained at intermediate frequencies.

Oscar homologs play a conserved role in Wolbachia-induced male-killing in Lepidoptera but not in other insects, highlighting the evolution of diverse male-killing mechanisms induced by Wolbachia.

Evolved gene expression changes in Drosophila simulans uncovered the interplay between parallel evolution, polymorphism, and pleiotropy and indicated that both direct and indirect effects of pleiotropy contribute to parallel evolution.

Evidence for those pathogen genes selected specifically for success on crops.

Single-nucleus RNA-sequencing of the hypothalamic preoptic area of monogamous and promiscuous deer mouse species reveals neuronal differences that may be responsible for innate changes in mating and parental care behavior.

The first comprehensive reconstruction of the evolutionary history of freshwater animals, on example of family Nemacheilidae, across Eurasia with the identification of the main tectonic, geological, and climatic factors influencing it has been described.

Experimental evolution of a duplicated gene increases mutational robustness relative to a single-copy gene but does not accelerate phenotypic evolution.

Meta-analysis reveals there is no evidence that variation in clutch size in birds is driven by the reproduction–survival trade-off.

Fitness defects arising from deletion of the gene encoding the bacterial equivalent of actin (mreB) are readily compensated by mutations affecting cell wall synthesis.
