Two new unicellular organisms reveal that coordinated contractions of groups of cells using actomyosin predated animal multicellularity during evolution.

Similar patterns of genomic divergence have been observed in the evolution of plant species separated by oceans.

Life-threatening S. aureus infections emerge from commensal nose bacteria in association with repeatable adaptive evolution.

Cooperativity between two transcription regulators occurs through protein-protein interactions with a general transcription factor complex and potentiates the parallel evolution of their DNA binding sites.

A gene duplication event has permitted the functional specialization of a homeodomain transcription factor through changes in exon-intron organization and these changes have supported the evolution of a major, phylum-level morphological novelty.

Regulatory evolution allows paralogs to escape from strucural pleiotropy.

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 convergent evolution of unusually strict substrate specificity in apicomplexan LDHs arose by classic neofunctionalization of a duplicated MDH gene via few mutations of large effect.

Some of the mutations that occur during influenza evolution can only be tolerated in conjunction with other mutations that increase the stability of a viral protein.

The evolution of insecticide-avoidance behaviour can be used to generate new spatial repellents to keep malaria vectors out of homes.
