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 ...

This is a pretty big deal. Here's the PhysOrg link I read. One of the posits of modern biology is that it took the widespread availability of oxygen to enable enough energy flow to make multicellular ...

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 ...

The transition from single-celled organisms to multicellular ones was a major step in the evolution of complex life forms. Multicellular organisms arose hundreds of millions of years ago, but the ...

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 ...

Researchers have discovered a mechanism steering the evolution of multicellular life. They identified how altered protein folding drives multicellular evolution. In a new study led by researchers from ...

Unicellular organisms show surprising complexity In a paper appearing in Nature Genetics, researchers discover that in more "primitive" unicellular organisms, both the adenine and the cytosine bases ...
