Two new unicellular organisms reveal that coordinated contractions of groups of cells using actomyosin predated animal multicellularity during evolution.
Wild baboons are an excellent model to study complex evolutionary processes such as speciation and hybridization, as well as the links between sociality, longevity and reproductive success.
An ancestral apical brain center contributed to the evolution of the insect central complex requiring foxQ2, which is essential for the development of midline structures of the insect brain.
When an essential metabolic gene in E. coli is mutationally inactivated, subsequent evolution rarely reverts the mutation to wild type but rather follows unexpected paths that rewire metabolic fluxes.

Bacteria growing in biofilms evolve antimicrobial resistance via different pathways and generate greater genetic diversity than well-mixed populations, selecting fitter but less resistant genotypes.
The way that bacteria grow—either floating in liquid or attached to a surface—affects their ability to evolve antimicrobial resistance and our ability to treat infections.

A new opsin receptor is light-sensitive and expressed in a unique type of photoreceptor in a flatworm that encloses over 400 sensory cilia within its cell membrane.
Using different sets of input sequences to evolutionary reconstruction algorithms results in the exploration of many possible models, the intergration over which produces significantly more accurate models.
