A genomic study of gut microbes during antibiotic use finds selective sweeps in a DNA gyrase gene that drive resistance.

His 1987 review, "Bacterial evolution," published in Microbiological Reviews (51:221-71, 1987), comprehensively summarizes work done over the previous 10 years on the new phylogenetic categorization ...

Bacterial evolution is the process of heritable change in populations of bacteria over multiple generations. It occurs through mechanisms including natural selection and genetic drift, and can ...

Scientists have used this oxygen surge and how microbes adapted to it to map out bacterial evolution. In a study published in Science, researchers from the Model-Based Evolutionary Genomics Unit at ...

Point mutations are often thought of as the raw material of evolution; these small changes ... us insights into the evolutionary pressures on bacterial pathogens.

Bacterial evolution and adaptation often depend on plasmids to support the transfer of genes, and are shaped by environmental factors. Our evolutionary map enables us to start exploring this on a ...

By using the planet-wide geological event of the Great Oxidation Event effectively as a "fossil" calibration point, our approach produced a detailed timeline of bacterial evolution. Combining ...

The organisms in the study are the only bacteria known to do this in this way, and studying them could help astrobiologists explain important steps in the evolution of life on Earth. The work is ...
