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 ...

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.

The bacteria-first theory, also known as the reductive hypothesis ... challenged microbiologists' longstanding theories on viral evolution. "These viruses were almost as big as bacteria and ...

The theory of evolution, he wrote ... comparing the genomes of members of the three domains of life—archaea, bacteria, and the eukaryotes (animals, plants, fungi, and protists)—have discovered ...

In the great upheaval of scientific thought that followed the announcement of the theory of ... elementary steps of evolution can be analyzed. For this purpose, the use of bacteria presents ...

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 ...

The bacteria is notoriously drug-resistant, and several antibiotic treatments are no longer effective in treating it. If evolution makes bacteria like this more invulnerable, prevention and ...

An international collaboration between four scientists from Mainz, Valencia, Madrid, and Zurich has published new research in ...

Scientists have helped to construct a detailed timeline for bacterial evolution, suggesting some bacteria used oxygen long before evolving the ability to produce it through photosynthesis.

Professor Pål Johnsen, co-senior author at the UiT The Arctic University of Norway, said: “Bacterial evolution and adaptation often depend on plasmids to support the transfer of genes, and are shaped ...

from microscopic bacteria to the blue whale, the biggest animal to ever live. Darwin and fellow naturalist Alfred Russel Wallace developed the theory of evolution in the mid-1800s. Evolution works ...
