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 ...

The earliest animal likely used chemical signaling to evolve from a single cell to a multicellular organism, according to a study led by an Indiana University Bloomington scientist. The findings ...

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 ...

It looks like a rotten Brussels sprout, but it’s a billion-year-old fossil. This enhanced microscope image shows an outer wall of sausage-shaped cells enclosing an inner cell mass. Image: Courtesy of ...

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 ...

How did life make the leap from single cells to coordinated, multicellular organisms? And how do genetically identical cells ...

In a remarkable development, scientists at Tufts University and the University of Vermont have created a new biological organism that can self-replicate. The discovery builds on earlier work creating ...

No, oxygen didn't catalyze the swift blossoming of Earth's first multicellular organisms. The result defies a 70-year-old assumption about what caused an explosion of oceanic fauna hundreds of ...

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 ...
