We've heard a lot about how important carbon and water are to life, but sulfur? Researchers think that sulfur may have actually been essential for organisms to make the transition from single-celled ...

A split-second stall at the start of genes may explain how complex animals evolved, according to the Cornell Chronicle. Researchers found that a brief “pause” in gene activity grew stronger and more ...

A major event in the evolution of organisms on earth was the development of complex, multicellular life forms made of eukaryotic cells, which are thought to have come from prokaryotic cells. Studies ...

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 ...

Biobots could one day be engineered to deliver drugs and clear up arterial plaque. Kriegman et al. 2020/PNAS, CC BY-SA Life and death are traditionally viewed as opposites. But the emergence of new ...

Newly discovered fossilized tracks suggest multicellular life could be 1.5 billion years older than previously thought, according to a new study. Newly discovered fossilized tracks suggest ...

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 ...

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 ...

A new study led by researchers at Yale and McGill University reveals how fluctuations in the Earth’s oxygen levels over 700 million years ago may have set the stage for the diversification of ...

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 ...

On the one hand, it would mean that multicellular life takes on average (ha!) 1.5 billion years less to evolve than we previously thought it would. 1.5 billion years is a very respectable difference, ...

Over 3,000 generations of laboratory evolution, researchers watched as their model organism, 'snowflake yeast,' began to adapt as multicellular individuals. In new research, the team shows how ...
