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 ...

The oldest trace fossils of a multicellular organism's movement were found in 2.1-billion-year-old strata in Gabon. It is presumed to have moved in search of food. Photo courtesy of PNAS Fossilized ...

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 ...

A new study by researchers at the University of Queensland is calling old ideas about evolution into question. The scientists used powerful genetic technologies to sequence every gene being expressed ...

Researchers from the Early Life Traces & Evolution Laboratory (Astrobiology / Faculty of Science) at the University of Liège have discovered the first in-situ evidence of chlorophyll remnants in a ...

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 ...

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 ...

Mistletoe might be a nice yuletide decoration, but it’s also a nefarious, parasitic badass that preys upon a series of hosts. Apparently one species has decided it no longer needs a protein that every ...

The diversity of unicellular eukaryotes covered in the study, with their nucleus (blue) and microtubule cytoskeleton (magenta) stained. These organisms are so distantly related to each other as they ...
