A 'hotspot' position in an olfactory receptor protein family underlies changes in odor tuning in different receptors at different times during evolution.

Experimentally evolved budding yeast populations reveal the role of contingency and chance in shaping the emergence and dynamics of pleiotropic effects of adaptation.

Intergenerational adaptations to stress play a critical role in organismal responses to changing environments and are largely lost or erased after one generation.

After experimentally simulated within-group conflict, dwarf mongoose bystanders engage in post-conflict management behaviour with a temporal delay.

Harmful genetic variants at mendelian disease genes slow down adaptation, by interfering with the spread of adaptive variants in a population.

Phylogenetic relationships between viral RNA segments are distinct between subtypes and lineages of seasonal human influenza A viruses and implicate RNA-RNA relationships as novel drivers of influenza virus evolution.

The repeated emergence of similar variants of influenza virus is linked to interactions between the virus’s RNA segments.

An analysis of the genomic features that distinguish conserved from species-specific circular RNAs reveals that the expansion of the downstream intron by insertion of retrotransposons stabilizes circular RNAs' production across 30+ millions years of evolution.

Evolutionary analyses suggest that most mammalian circRNAs did not emerge from common ancestral circRNA precursors, arguing against widespread functional conservation.

Irreversible differentiation into somatic cells is evolutionarily optimal if changing cell phenotype is costly, a few somatic cells already improve the organism's performance, and the organism is large enough.
