Who were our earliest ancestors? The answer could lie in a special group of single-celled organisms with a cytoskeleton ...

According to this latest study, all complex life forms (a.k.a. eukaryotes) trace their roots back to a common ancestor among a group of microbes called the Asgard archaea.

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 ...

Since the late 1980s, all life forms have been split into three groups on the phylogenetic tree of life: bacteria, archaea, and eukaryotes. Eukaryotes and archaea have long been considered “sister ...

Scientists propose that the eukaryotic branch of this family tree formed when two prokaryotes ... systems to study the distribution of complete systems in the genomes of archaea, including Asgard ...

and they were first comprehensively surveyed across the tree of life only eight years ago. Since then, the number of known microbial species has exploded, particularly archaea, which hide out in ...

To understand how such complexity emerged and the mechanisms in which is regulated, we aim to study the cell biology of Archaea. Low-resolution tree of life representing the distribution and ...

The model — which was trained on 128,000 genomes spanning the tree of life, from humans to single-celled bacteria and archaea — can write whole chromosomes and small genomes from scratch.
