Paleontologists have found fossilized multicellular marine algae, or seaweed, dating back more than 555 million years, ranking among the oldest examples of multicellular life on Earth. Honing in on ...

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 ...

The origin of animal multicellularity is one of the major evolutionary transitions in the history of life. The identification and phylogenetic classification of the closest unicellular relatives of ...

The snowflake yeast had been shipped from William Ratcliff’s laboratory at the Georgia Institute of Technology in the U.S. Regular yeast — the same organism that makes bread fluffy — grows as a single ...
