    Symbiont location, host fitness, and possible coadaptation in a symbiosis between social amoebae and bacteria

    Longfei Shu et al.
    Morphological and fitness defects imposed on amoebae hosts by Burkholderia symbionts demonstrates symbiont species-specific effects and provides evidence of host adaptation to naturally acquired symbionts.

    Fitness benefits in fluoroquinolone-resistant Salmonella Typhi in the absence of antimicrobial pressure

    Stephen Baker et al.
    The major evolutionary routes to drug resistance in Salmonella Typhi are associated with fitness benefits, not fitness costs, implying that prudent antimicrobial use will have no effect as a public health intervention in controlling typhoid fever.

    Point of View: Towards a mechanistic foundation of evolutionary theory

    Michael Doebeli et al.
    A description of evolution that is based on birth-death processes, and in which fitness is at most a derived quantity, is advocated.

    Point of View: Is cell size a spandrel?

    Ariel Amir
    Analysis of experiments on bacteria suggests that the dependence of cell size on growth rate is not an adaptation but a causal consequence of a regulatory mechanism that controls DNA replication.
