A gain-of-function in a new chemical defense resulted in no trade-offs and and independent evolution between novel and ancestral defenses, suggesting low redundancy among different defensive chemicals.

Variation in migration can evolve rapidly and traits that comprise this behaviour may be determined by standing variation at a few regulatory regions that are not common across taxonomic groups.

Astyanax mexicanus surface-dwelling fish exposed to complete darkness develop many traits resembling cavefish adaptations by phenotypic plasticity in a single generation.

Skin-associated bacteria underlie the production of a potent defensive neurotoxin in newts, impacting host physiology, molecular evolution, and predator-prey interactions in a coevolutionary arms race.

Artificial selection on wing color and CRISPR/Cas9 knockout of the optix gene both alter scale lamina thickness in Junonia coenia, which shifts structural color wavelength and mimics macroevolutionary butterfly diversity.

The first overview of fitness interactions within a species provides information how genetic interactions and ecology combine together to determine trait evolution.

Experiments on mice have shown that developmental processes are influencing the generation of phenotypic variation in a way that shapes evolution.

Evolutionary adaptation to a constitutive perturbation of DNA replication reveals that adaptive mutations in three conserved pathways interact to restore faithful chromosome replication and segregation.

Environmental conditions strongly impact the fitness effects of Hsp90, resulting in the selection of Hsp90 sequences in nature that are robust to a variety of stressful conditions.

Mitochondrial inner membrane translocation of presequence-containing proteins by the single bifunctional TIM complex of T. brucei requires an non-canonical J domain-containing protein.
