Genome dynamics during experimental evolution [PDF]
Nature Reviews Genetics, 2013 Evolutionary changes in organismal traits may occur either gradually or suddenly. However, until recently, there has been little direct information about how phenotypic changes are related to the rate and the nature of the underlying genotypic changes.

Genetic Polymorphism Drives Susceptibility Between Bacteria and Bacteriophages
Frontiers in Microbiology, 2021 Phage therapy has attracted much attention for the treatment of antibiotic-resistant bacteria in recent years. However, it is common for bacteria to obtain resistance capability in short time after interaction with a lytic phage, as observed in phage ...

Heredity, 2008 This chapter reviews experimental evolution. Many of the evolutionary processes extend over long periods of time—long, that is, on human timescales of a few decades. With the resource of a laboratory, we can follow the evolution of large populations over thousands of generations in a few months.

Escherichia coli with a Tunable Point Mutation Rate for Evolution Experiments
G3: Genes, Genomes, Genetics, 2020 The mutation rate and mutations’ effects on fitness are crucial to evolution. Mutation rates are under selection due to linkage between mutation rate modifiers and mutations’ effects on fitness.

Bacterial evolution and the Bak-Sneppen model [PDF]
, 2001 Recently, Lenski et al \cite{Elena,Lenski,Travisano} have carried out several experiments on bacterial evolution. Their findings support the theory of punctuated equilibrium in biological evolution. They have further quantified the relative contributions

A novel decoy strategy for polymyxin resistance in Acinetobacter baumannii
eLife, 2021 Modification of the outer membrane charge by a polymyxin B (PMB)-induced PmrAB two-component system appears to be a dominant phenomenon in PMB-resistant Acinetobacter baumannii.

Evolution of Gluon Spin in the Nucleon [PDF]
, 1997 We examine the $Q^2$ evolution of gluon polarization in polarized nucleons. As is well known, the evolution of $\alpha_s \Delta G(Q^2)$ is negligible for typical momentum transfer variations found in experimental deep inelastic scattering.

Experimental evolution recapitulates natural evolution
Philosophical Transactions of the Royal Society of London. Series B: Biological Sciences, 2000 Genomes of the closely related bacteriophages ϕX174 and S13 are 5386 bases long and differ at 114 nucleotides, affecting 28 amino acids. Both parental phages were adapted to laboratory culture conditions in replicate lineages and analysed for nucleotide changes that accumulated experimentally.
