Researchers have discovered that virus-like nanoparticles can promote the multicellular organization and reproduction of host bacteria. These particles, which are evolutionarily related to phages ...

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 ...

Throughout the history of life on Earth, multicellular life evolved from single cells numerous times, but explaining how this happened is one of the major evolutionary puzzles of our time. However, ...

How low can worms go? According to a new study, at least 0.8 miles (1.3 kilometers) below the Earth's surface. That's the depth at which scientists discovered a new species of worm, dubbed ...

Scientists are discovering ways in which single cells might have evolved traits that entrenched them into group behavior, paving the way for multicellular life. These discoveries could shed light on ...

A newly discovered group of 2.1-billion-year-old fossil organisms may be the earliest known example of complex life on Earth. They could help scientists understand not just when higher life forms ...

For billions of years, single-celled creatures had the planet to themselves, floating through the oceans in solitary bliss. Some microorganisms attempted multicellular arrangements, forming small ...

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 ...

In the multicellular soil bacterium Streptomyces coelicolor, some cells start producing lots of antibiotics after mutations delete big chunks of their genomes. Now a computer model has helped to ...

Cell division allows for growth and replacement of dead cells. Most multicellular organisms are made of different cell types that are specialised to carry out specific functions. Revise: Control and ...
