Ten years ago, nobody knew that Asgard archaea even existed. In 2015, however, researchers examining deep-sea sediments ...

New research sheds light on one of the biggest questions in biology: where did complex life come from? The answer may lie ...

Who were our earliest ancestors? The answer could lie in a special group of single-celled organisms with a cytoskeleton similar to that of complex organisms, such as animals and plants.

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

Scientists reveal the role of hidden microbes called Asgard archaea in the origins of complex life, challenging long-held ...

ETH researchers discovered related structures in Asgard archaea and describe their structure. These experiments show that ...

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

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.

Prokaryotes are organisms whose cells lack a nucleus and other organelles. Prokaryotes are divided into two distinct groups: the bacteria and the archaea, which scientists believe have unique ...

“This should have a major effect on textbook treatment of these subjects.” Since the late 1980s, all life forms have been split into three groups on the phylogenetic tree of life: bacteria, archaea, ...
