Some single-celled organisms are known to transition to multicellularity during their lifetimes, usually either by cloning themselves or when many similar cells come together to form a larger ...

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 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 ...

Scientists in Japan have discovered a previously unknown giant virus, offering new insight into this enigmatic category of viruses – and possibly also into the origins of multicellular life. The virus ...

For 165 years, the giant fossil Prototaxites taiti puzzled scientists. Standing 26 feet tall, it may belong to an unknown ...

Life and death are traditionally viewed as opposites. But the emergence of new multicellular life-forms from the cells of a dead organism introduces a “third state” that lies beyond the traditional ...

Horodyskia, characterized by a string of beads with uniform size and spacing, is a kind of macroscopic fossil with a record extending from the early Mesoproterozoic Era (~1.48 Ga) to the terminal ...

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 global positioning system (GPS) can keep you from getting lost, manage air traffic, and track the migration of endangered species. And in a new study published today by Nature, it’s helped ...

Life and death are traditionally viewed as opposites. However, the emergence of new multicellular life forms from the cells of a dead organism introduces a “third state” that lies beyond the ...

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 ...

One-celled organisms began influencing life once their descendants achieved multicellularity. Researchers once thought that this multicellularity transition was rather explosive, but it turns out that ...
