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 ...

In a remarkable development, scientists at Tufts University and the University of Vermont have created a new biological organism that can self-replicate. The discovery builds on earlier work creating ...

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 ...

Swarms of tiny living robots can self-replicate in a dish by pushing loose cells together. The xenobots – made from frog cells – are the first multicellular organisms found to reproduce in this way.

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 ...

Researchers from the Early Life Traces & Evolution Laboratory (Astrobiology / Faculty of Science) at the University of Liège have discovered the first in-situ evidence of chlorophyll remnants in a ...

No, oxygen didn't catalyze the swift blossoming of Earth's first multicellular organisms. The result defies a 70-year-old assumption about what caused an explosion of oceanic fauna hundreds of ...

Scientists have identified a new species of microscopic worms living in the ground below South African mines, isolated from fracture water gushing up from miles below the Earth's surface. It is the ...

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 ...

The diversity of unicellular eukaryotes covered in the study, with their nucleus (blue) and microtubule cytoskeleton (magenta) stained. These organisms are so distantly related to each other as they ...

Long before plants and animals existed, Earth was dominated by microscopic organisms called prokaryotes. They lived simple, single-celled lives, soaking up nutrients in the oceans billions of years ...
