Why did multicellularity arise? Solving that mystery may help pinpoint life on other planets and explain the vast diversity and complexity seen on Earth today, from sea sponges to redwoods to human ...

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. But the emergence of new multicellular life-forms from the cells of a dead organism introduces a “third state” that lies beyond the traditional ...

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 ...

All the living things that we can see evolved from those that we can’t. Every human, bird, tree, and flower can trace its ancestry across a few billion years back to microscopic, single-celled ...

Scientists at Nagoya University in Japan have identified the genes that allow an organism to switch between living as single ...

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 ...

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 ...

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 ...

The spherical fossils came from sediments that were formerly at the bottom of a lake. When you purchase through links on our site, we may earn an affiliate commission. Here’s how it works. Scientists ...

The world would look very different without multicellular organisms – take away the plants, animals, fungi, and seaweed, and Earth starts to look like a wetter, greener version of Mars. But precisely ...
