Eukaryotes are thought to have originated through a process known as endosymbiosis, in which an ancestral prokaryotic cell engulfed another, forming a mutually beneficial relationship. Over time, the ...

Penn State researchers propose that Earth and life have evolved together in a way that is more typical of life-supporting planets.

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 ...

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

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.

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

This study focused on exploring the distribution patterns, driving factors and microbial interaction patterns of methane-metabolizing microorganisms along the sedimentation gradient in the Yellow ...

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 ...
