Enzyme evolution is reversible on a structural and functional (phenotypic) level, but through a different mutational pathway that leads to genotypic incompatibility with the ancestor.

Essays on the wild lives of model organisms, from Arabidopsis to the zebrafish.

A new hominin species found in a South African cave is part of one of the most unusual hominin fossil assemblages on record.

A new hominin species has been unearthed in the Dinaledi Chamber of the Rising Star cave system in the largest assemblage of a single species of hominins yet discovered in Africa.

A gene regulatory network model provides a simplified explanation of the molecular interactions that orchestrate muscle development in the sea urchin embryo.

A shift in antero-posterior positional information may contribute to the fin-to-limb transformation.

Experimental mapping of the joint sequence space of an ancient transcription factor (TF) and its DNA binding sites reveals that epistasis across the molecular interface permitted the evolution of a new and specific TF-DNA complex.

In-lab evolution of synthetic promoters has revealed a novel general mechanism for de novo evolution of gene regulation, and highlights the crucial role of expression noise in this process.

The overexpression of RNA chaperones, including several DEAD box RNA helicases, enhances the fitness of mutationally compromised E. coli strains.
