In 1977, Woese and Fox proposed the Archaea as a new domain of life and that the tree of life is divided into three branches — the Eukarya, Bacteria and Archaea. Although a three-domain tree was ...

Scientists trace an ancient microbe, Asgard archaea, that gave rise to humans, animals, and plants more than 2 billion years ...

Ten years ago, nobody knew that Asgard archaea even existed. In 2015, however, researchers examining deep-sea sediments discovered gene fragments that indicated a new and previously undiscovered form ...

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 biodiversity of the Earth never ceases to astonish. One example that has radically changed the face of biology is the discovery of a group of organisms called archaea (pronounced “ar-kee-ah”). It ...

Thanks to a wealth of new genomic sequence data, the family tree of Archaea, which encompassed just two phyla 16 years ago, has exploded in recent years. It now includes more than a dozen phyla, ...

The tree of life, which depicts how life has evolved and diversified on the planet, is getting a lot more complicated. Researchers at UC Berkeley, who have discovered more than 1,000 new types of ...

Microbiology has always been about recognizing the scale of what is unknown. In the beginning, the unknown was that microbes existed at all. The invention of the microscope proved that these tiny, ...

A family tree showing representatives of the major groups (phyla) of microbes in different colors. Names in red are the first 56 genomes sequenced for the Genomic Encyclopedia of Bacteria and Archaea.

In 1977, Woese and Fox proposed the Archaea as a new domain of life and that the tree of life is divided into three branches — the Eukarya, Bacteria and Archaea. Although a three-domain tree was ...
