Animals like dinosaurs might come to mind when it comes to ancient species, but scientists found that this surprising species ...

In multicellular organisms like Daphnia, a type of tiny aquatic animal, the energy demands increase significantly with size, but this general principle appears to extend to all other animals, ...

The world would look very different without multicellular organisms—take away the plants, animals, fungi, and seaweed, and Earth starts to look like a wetter, greener version of Mars. But precisely ...

In a groundbreaking experiment, researchers have brought a mouse to life with the help of a single-celled organism that existed long before any multicellular animals walked the earth. Genetic research ...

A new study shows that multicelled organisms like the metazoan daphnia (pictured) require a tenfold increase in energy compared with protists for their growth, maintenance and survival. The high cost ...

Coordination between individuals is a fundamental challenge in collectives, and this is just as true for a country’s government as it is for simple multicellular organisms. How does a group of many ...

Researchers have discovered a mechanism steering the evolution of multicellular life. They identified how altered protein folding drives multicellular evolution. Researchers have discovered a ...

The evolutionary origin of sperm can be traced back to a single-celled ancestor of all living animals. Almost all animals reproduce by having a single-celled stage of their life cycle, involving two ...

The original version of this story appeared in Quanta Magazine. Once upon a time, long ago, the world was encased in ice. That’s the tale told by sedimentary rock in the tropics, many geologists ...
