For many years, scientists believed that life in Utah’s Great Salt Lake was extremely limited. Its caustic, hyper-saline ...

Learn how one-celled organisms, or single-celled organisms, helped build complex life.

As organisms develop from embryos, groups of cells migrate and reshape themselves to form all manner of complex tissues.

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 ...

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 ...

Over 150 years ago, a fossilized organism known as Prototaxites emerged as an enigma regarding what early land life may have been like. As an organism that appeared to grow up through Earth’s crust in ...

Scientists at Nagoya University in Japan have identified the genes that allow an organism to switch between living as single cells and forming multicellular structures. This ability to alternate ...

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 ...

While mirror bacteria may sound like a fun time, a group of 40 renowned scientists conclude it is probably not worth the risk.

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 ...

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 ...

An ancient and enormous organism called Prototaxites, initially found to be a type of fungus, may actually be an unknown ...
