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 ...

In the mid-1990s, scientists made a discovery that shook up the understanding of life on Earth: vast reservoirs of microbes ...

In the three-domain model, eukaryotes belong to a separate branch that shares a common ancestor with archaea. But phylogenetic analyses suggest that complex cells emerged from within the archaea. This ...

In samples gathered at Obsidian Pool, using PCR and other methods, the team found many new life-forms within Archaea, a vast and anomalous domain distinct from bacteria. The park’s role in ...

On one side there are the tiny bacteria and archaea, collectively known as prokaryotes. On the other side there are the huge and unwieldy eukaryotes, the third great domain of life. A typical ...

which had higher diagnostic accuracy in identifying both males and females with ASD compared with panels of gut microbiome markers from a single kingdom (such as bacteria or archaea). The authors ...
