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 ...

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 ...

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 ...

When the slime mold Dictyostelium discoideum runs out of food, sulfur limitation drives its development from a unicellular to a multicellular organism. Researchers now present the nutrient signaling ...

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 ...

Micro-organisms constitute a very antique group of living organisms which appeared on the Earth’s surface almost 3000 million ...

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 ...

Scientists have discovered the fossil of what may be the earliest multicellular animal ever found. Dating back a billion years, the microscopic fossil contains two distinct cell types, potentially ...

A team of scientists, led by the University of Sheffield in the UK and Boston College in the U.S., has found a microfossil in the Scottish Highlands which contains two distinct cell types and could be ...

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

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 ...
