For a billion years, single-celled eukaryotes ruled the planet. Then around 700 million years ago during Snowball Earth—a geologic era when glaciers may have stretched as far as the Equator—a new ...

A team of scientists, led by the University of Sheffield in the UK and Boston College in the U.S., has found a microfossil in the Scottish Highlands which contains two distinct cell types and could be ...

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 ...

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 ...

Life and death are traditionally viewed as opposites. But the emergence of new multicellular life-forms from the cells of a dead organism introduces a “third state” that lies beyond the traditional ...

Life’s leap from single-celled to multicellular organisms marks a pivotal moment in evolutionary history. This transformation laid the foundation for the complex life forms we see today. By studying ...

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 ...

New studies by the Max Planck Institute for Evolutionary Biology show that competition between different evolutionary developmental stages of multicellular life cycles can be important for the ...

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 conditions lethal to ...

All the living things that we can see evolved from those that we can’t. Every human, bird, tree, and flower can trace its ancestry across a few billion years back to microscopic, single-celled ...

After a decade-long quest to fill a major gap in basic biology, UChicago scientists have built a complete map of how cells ...

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 ...
