    Predictable properties of fitness landscapes induced by adaptational tradeoffs

    Suman G Das et al.
    Adaptational tradeoffs constrain the evolutionary pathways towards antimicrobial resistance, but highly fit mutants are nevertheless likely to arise at any concentration of the drug.

    Adaptation in protein fitness landscapes is facilitated by indirect paths

    Nicholas C Wu et al.
    The extra dimensions in protein sequence space open up indirect paths of adaptation and alleviate the constraint on the selective accessibility to high fitness genotypes.

    Determination of ubiquitin fitness landscapes under different chemical stresses in a classroom setting

    David Mavor et al.
    Chemical perturbation-dependent deep mutational scanning data collected by a lab-based interdisciplinary graduate class resolves a paradox between the high evolution conservation and the high mutational tolerance of the protein ubiquitin.

    Inferring genetic interactions from comparative fitness data

    Kristina Crona et al.
    A new mathematical approach can infer higher order genetic interactions from pairwise fitness comparisons between genotypes.

    Population genomics of intrapatient HIV-1 evolution

    Fabio Zanini et al.
    Whole genome deep sequencing of many longitudinally sampled HIV-1 populations reveals that reversions towards ancestral HIV-1 genome sequences occur throughout the course of infection.

    Rank orders and signed interactions in evolutionary biology

    Kristina Crona
    Rectangular order perturbations generalize sign epistasis, capture global aspects of fitness landscapes, and clarify how rank order approaches relate.

    Global epistasis emerges from a generic model of a complex trait

    Gautam Reddy, Michael M Desai
    Predictable patterns of fitness evolution observed in microbial evolution experiments can emerge generically as a consequence of widespread epistatic interactions between mutations.

    Adaptation to mutational inactivation of an essential gene converges to an accessible suboptimal fitness peak

    João V Rodrigues, Eugene I Shakhnovich
    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.

    Atypical meiosis can be adaptive in outcrossed Schizosaccharomyces pombe due to wtf meiotic drivers

    María Angélica Bravo Núñez et al.
    The wtf meiotic drivers change the fitness landscape of meiosis in outcrossed Schizosaccharomyces pombe demonstrating that genetic parasites can favor the evolution of variants that disrupt meiotic fidelity.

    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.
