Scaling up from one cell to many may have been a small step rather than a giant leap for early life on Earth. A single-celled organism closely related to animals controls its life cycle using 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 ...

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 ...

A new study shows that multicelled organisms like the metazoan daphnia (pictured) require a tenfold increase in energy compared with protists for their growth, maintenance and survival. The high cost ...

Researchers find that oxygenation of Earth's surface is key to the evolution of large, complex multicellular organisms. If cells can access oxygen, they get a big metabolic benefit. However, when ...

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 ...

Researchers have discovered that environments favoring clumpy growth are all that’s needed to quickly transform single-celled yeast into complex multicellular organisms. To human eyes, the dominant ...
