Scientists have debated where Prototaxites belong in the tree of life for over a century, but now a new study suggests it ...

Asgard archaea may have led to the evolution of eukaryotic life ETH Zurich researchers identify actin and microtubule ...

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 ...

A recent study has shown that they also have the potential to fix inorganic carbon—in the form of carbon dioxide (CO2)— to generate acetate, an important fuel for other sediment-dwelling organisms ...

Archaea are organisms consisting of a single cell without a nucleus and with distinct structural, physiological and evolutionary characteristics. They inhabit a wide range of habitats, including ...

Finally, the three-domain structure of Woese's tree (Figure 1a) shows that evolutionary history is decoupled from biological organization. Indeed, archaea and bacteria appear very similar ...
