Codon optimization through biased synonymous substitutions is a characteristic feature of the genomes of generalist fungal parasites and is associated with the colonization of multiple hosts.

Flowers of different plant species show distinct and highly diverse patterns of temperature across their surfaces, and bumblebees are able to differentiate between these previously unnoticed but widespread floral cues.

The divergence of gene regulation during evolution in yeast traces phylogenetic distance with prominent changes being associated with changes in lifestyle and a whole genome duplication event.

The range of footfall patterns seen in walking amphibians, reptiles and mammals, including hippopotamus, horse and (inverted) sloth, are consistent with simple principles of mechanical work minimization.

Chicken ANP32A, and not chicken ANP32B, supports influenza polymerase activity and thus editing of this single gene may generate chickens that are resilient to influenza virus infection.

In teleost fishes, the independent evolution of electrosensory systems was repeatedly associated with evolutionary changes in brain region scaling that were independent of changes in brain–body allometry.

In the dioecious plant genus Leucadendron, shifts to sex-biased gene expression occurred predominantly in genes with ancestrally high rates of expression evolution, and were not correlated with morphology.

Reconstruction of great auk population dynamics suggests that hunting pressure alone could have been responsible for their extinction, demonstrating that even abundant, widespread species can be vulnerable to intense exploitation.

Treating color patterns in a geometric morphometrics framework reveals rapid rates of color evolution that are explained by a combination of intrinsic organismal features (color variation among patches) and geography within a cosmopolitan radiation of birds.
