whereas the oblong red shape denotes a typical archaeon with a cell wall. A: archaea; B: bacteria; E: eukaryote; LUCA: last universal common ancestor of cellular life-forms; LECA: last eukaryotic ...

In 2015, researchers examining deep-sea sediments near the underwater volcano Loki discovered gene fragments indicating a new ...

Cellular Organization and Behavior in the Archaea domain of life How the evolution of molecular systems shaped the function and behavior of cells and created the life diversity observed today is still ...

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 ...

Like bacteria, archaea are single-celled organisms. Genetically, however, there are significant differences between the two domains, especially regarding their cell envelopes and metabolic processes.

Asgard archaea emerged as a key piece in the puzzle of how complex life evolved, acting as a potential link between simple archaea and eukaryotes—organisms like plants and animals whose cells contain ...
