Experimental evolution gone wild [PDF]
Journal of The Royal Society Interface, 2015 Because of their large population sizes and rapid cell division rates, marine microbes have, or can generate, ample variation to fuel evolution over a few weeks or months, and subsequently have the potential to evolve in response to global change.

Frontiers in Microbiology, 2020 Plasmids can provide advantageous traits to host bacteria, although they may impose a fitness cost. Chromosome-encoded factors are important for regulating the expression of genes on plasmids, and host chromosomes may differ in terms of their ...

Selection and the direction of phenotypic evolution
eLife, 2023 Predicting adaptive phenotypic evolution depends on invariable selection gradients and on the stability of the genetic covariances between the component traits of the multivariate phenotype.

Behavior out of control: experimental evolution of resistance to host manipulation [PDF]
, 2019 Many parasites alter their host's phenotype in a manner that enhances their own fitness beyond the benefits they would gain from normal exploitation. Such host manipulation is rarely consistent with the host's best interests resulting in suboptimal and ...

Protein Structure from Experimental Evolution [PDF]
Cell Systems, 2020 Natural evolution encodes rich information about the structure and function of biomolecules in the genetic record. Previously, statistical analysis of co-variation patterns in natural protein families has enabled the accurate computation of 3D structures. Here, we explored generating similar information by experimental evolution, starting from a single

Improved use of a public good selects for the evolution of undifferentiated multicellularity
eLife, 2013 We do not know how or why multicellularity evolved. We used the budding yeast, Saccharomyces cerevisiae, to ask whether nutrients that must be digested extracellularly select for the evolution of undifferentiated multicellularity.

Relaxed Substrate Specificity in Qβ Replicase through Long-Term In Vitro Evolution
Life, 2021 A change from RNA- to DNA-based genetic systems is hypothesized as a major transition in the evolution of early life forms. One of the possible requirements for this transition is a change in the substrate specificity of the replication enzyme.

Transverse parton momenta in single inclusive hadron production in ${e^ + }{e^ - }$ annihilation processes [PDF]
, 2017 We study the transverse momentum distributions of single inclusive hadron production in ${e^ + }{e^ - }$ annihilation processes. Although the only available experimental data are scarce and quite old, we find that the fundamental features of transverse ...

eLife, 2013 Selection favours single-celled mutants that stick together when a sugar needed for growth is in short supply, suggesting that multicellular life may have evolved as a by-product of selection for more efficient usage of resources.
