Bacteriophage can rapidly evolve resistance to anti-phage defense elements in bacteria by amplifying latent counter-defense genes, though this amplification comes at a cost of compensatory deletions that eliminate other counter-defense genes.

Fruit consumption of Jeholornis was evidenced and indicates seed dispersal was present from early in avian radiation.

Analysis of protein interfaces suggests cotranslational assembly can be an adaptive process, likely serving to minimise non-specific interactions with other proteins in the cell.

Interactions between a mobile resistance gene and chromosomal mutations drive the evolution of high-level antibiotic resistance.

Yeast populations lose mutational robustness during evolution in one environment but not in another due to the collective effect of a large number of idiosyncratic epistatic interactions.

Specific evolutionary gene loss signatures indicated an eye-related function for the uncharacterized SERPINE3 gene, which was experimentally confirmed by zebrafish gene knockouts, showing how comparative genomics can provide insights into the function of uncharacterized genes.

Comparing the genomes of mammals which evolved to have poor vision identifies an important gene for eyesight.

The rhesus macaque is a non-human primate that is widely used as a model organism in ecology, evolutionary biology and behavioural science.

μCT-aided study illuminates the cranial endoskeleton and interrelationships of the Permian actinopterygian †Brachydegma, which is now excluded from crown neopterygians despite exhibiting a double jaw joint.

Canadian COVID-19 travel restrictions imposed in March 2020 greatly reduced SARS-CoV-2 importations, but were insufficient to prevent new sublineages of similar transmissibility from being introduced and replacing early sublineages.
