A new suggestion that complexity increases over time, not just in living organisms but in the nonliving world, promises to ...

Single-celled organisms that group together can generate stronger water currents to pull in food, a benefit that may have ...

Tiny magnetic bacteria that live in tightly bound groups are showing scientists how life might have evolved complex, multicellular forms. These rare bacteria can’t survive alone – they depend on one ...

But scientists have found that a more complex organism — a single-celled alga with a nucleus — can do it, too, thanks to a newly identified piece of cellular architecture. They're calling it ...

“These single-cell organisms can do things that we assume are limited to more complex organisms,” said Shashank Shekhar, a biophysicist at Emory University in Atlanta who is the lead author of ...

The stentor’s multicellular-like behavior could be used as a model system to help understand how life evolved from single-cell organisms to complex organisms like humans — made up of trillions ...

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 ...

The fluid dynamics of cooperative feeding may have sparked single cells to assemble into complex, multicellular life, as ...

An ancient and enormous organism called Prototaxites, initially found to be a type of fungus, may actually be an unknown ...

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