Synonymous mutations can have highly variable fitness effects stemming from changes in transcription, some of which contribute to adaptation.

Applying ancestral sequence reconstruction techniques to protein kinases reveals the mutations that underlie different modes of activation.

Tight regulation of a central developmental kinase cascade evolved through two key mutations.

When landing, Pacific parrotlets exhibit stereotyped leg and wing dynamics regardless of perch diameter and texture, but foot and claw kinematics become surface-specific upon touchdown to successfully grasp the perch.

The fungal parasite Podosphaera plantaginis employs both sexual and asexual reproduction to increase its chances of infecting the plant Plantago lanceolata.

In natural pathogen populations opportunities for sexual outcrossing vary, leading to spatial variation in genetic diversity and between-season survival.

Evolutionary reconstruction of the ecdysis pathway shows that its major elements are present in the majority of metazoans, providing evidence that they originated much earlier than currently assumed.

Spok genes are meiotic drivers that increase their own chances of transmission by killing gametes that do not inherit them.

Members of a single gene family determine the genomic basis of multiple coexisting meiotic drive elements in natural populations of Podospora.

Horizontal gene transfer (HGT) analysis in polyextremophile red algae (Cyanidiales) provides explanations for the nonexistence of cumulative effects and eukaryotic pangenomes, and highlights differences between HGT and native genes.
