A major evolutionary theory says most genetic changes don’t really matter, but new evidence suggests that’s not true. Researchers found that helpful mutations happen surprisingly often. The twist is ...

This article is a summary of Roy Ratcliffe’s recently released book ‘Life on Earth’ (Past, Present and Future)’. Of all the millions of species of life that have existed on earth over billions of ...

The researchers think the pattern they observed in ants reflects a more universal trend in the evolution of societal ...

The origin of organisms with complex cells, known as eukaryotes, is one of the most crucial parts of life’s evolutionary story. All animals, plants, and fungi are eukaryotes, and if complex cells had ...

Fungi arose long before plants, shaping Earth with early soils and nutrient cycles. Their hidden legacy shows they may have prepared the world for life to flourish on land. Credit: Shutterstock ...

Humans often view being multicellular as an advantage, but most life on Earth is single-celled, thriving in extreme conditions. The evolution of multicellular life, starting about 2.5 billion years ...

Single-celled organisms that group together can generate stronger water currents to pull in food, a benefit that may have encouraged early life forms to assemble into colonies, according to a new ...

The mystery of how multicellular life evolved has long baffled scientists, who've spent years trying to understand how solitary single-celled organisms began living in unison and triggered the ...

Stentor coeruleus is a giant unicellular, filter-feeding protist that uses the coordinated motion of its oral ciliary structure to generate feeding currents. These currents allow the organism to ...

WOODS HOLE, Mass. -- Humans like to think that being multicellular (and bigger) is a definite advantage, even though 80 percent of life on Earth consists of single-celled organisms – some thriving in ...

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 ...
