How do scientists study and classify life-forms? How can we understand the complex evolutionary connections between living organisms? Woese's breakthrough was momentous for at least three reasons.

Earth’s immense web of life fill three broad domains—archaea, bacteria, and eukarya. Scientists from Monash University recently discovered hydrogen-producing enzymes in archaea, which were thought to ...

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 ...

In many submerged regions, murky mud shelters strange life-forms that seem to be the key to one of the biggest mysteries of life on Earth. These creatures belong to a domain of life called the archaea ...

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. Ten years ago, ...

A new version of Evo, the AI developed at the Arc Institute that can be used to design genomes as long as that of a bacterium, has been retrained with the DNA sequences of three domains of life – ...

Compressing a type of single-celled microorganism makes it develop into a multicellular tissue-like structure with different cell types. This suggests that pressure can help drive key evolutionary ...
