A new “tree of life” has been constructed by researchers at the Virginia Bioinformatics Institute (VBI) at Virginia Tech for the gamma-proteobacteria, a large group of medically and scientifically ...

Scientists have found further evidence to support the idea that the primary two domains of life, the Archaea and Bacteria, are separated by a long phylogenetic tree branch and therefore distantly ...

The latest Virtual Issue from Genome Biology and Evolution highlights articles that provide new insight into the deep evolutionary relationships among extant organisms and the origin of eukaryotes ...

An international team of researchers have found a new way to interpret the evolution of bacteria. The findings, published in the journal Science today, demonstrate how integrating vertical descent and ...

A mouse gut bacteria phylogenetic tree is superimposed over a microphotograph of small intestine tissue, showing the abundance of bacteria by the size of the circles. Red circles indicate bacteria ...

Antibiotic resistance is a tough problem—one some biologists worry cannot be solved with a business-as-usual approach to drug development. So researchers led by Gerard D. Wright at McMaster University ...

Phylogenies show how organisms are related to each other by placing them in an ordered map of them and their relatives. These can be done on a large scale, such as the tree of life, or on a smaller ...
