Bacterial genomics has greatly expanded our understanding of microdiversification patterns
within a species, but analyses at higher taxonomical levels are necessary to understand and …

A novel moderately thermophilic, facultatively anaerobic chemoorganotrophic bacterium
strain P3M‐2 T was isolated from a microbial mat developing on the wooden surface of a …

Species richness varies dramatically among clades across the Tree of Life, by over a million-
fold in some cases (eg placozoans versus arthropods). Two major explanations for …

Submarine hydrothermal vents above serpentinite produce chemical potential gradients of
aqueous and ionic hydrogen, thus providing a very attractive venue for the origin of life. This …

The increasing size of timetrees in recent years has led to a focus on diversification analyses
to better understand patterns of macroevolution. Thus far, nearly all studies have been …

The yellow gene family is intriguing for a number of reasons. To date, yellow-like genes
have only been identified in insect species and a number of bacteria. The function of the …

The traditional tree of life from molecular biology with last universal common ancestor
(LUCA) branching into bacteria and archaea (though fuzzy) is likely formally valid enough to …

It is generally assumed that all bacteria must have at least one rRNA operon (rrn operon) on
the chromosome, but some strains of the genera Aureimonas and Oecophyllibacter carry …

Lateral gene transfer (LGT)—which transfers DNA between two non-vertically related
individuals belonging to the same or different species—is recognized as a major force in …

Cells contain a multitude of protein complexes whose subunits interact with high specificity.
However, the number of different protein folds and interface geometries found in nature is …
