Scientists have discovered the fossil of what may be the earliest multicellular animal ever found. Dating back a billion years, the microscopic fossil contains two distinct cell types, potentially ...

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 ...

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 ...

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 ...

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 ...

MIT geochemists offer compelling evidence that ancient sea sponges were Earth's first animals, emerging over 541 million years ago. By analysing chemical fossils in rocks, researchers identified ...

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 ...

A fossilised prehistoric organism discovered in 2017 has led scientists to conclude that eggs emerged long before the first animals evolved, implying that they came before chicken. Chromosphaera ...

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 ...
