A strange "fossil worm" has been discovered in Siberia. It showed no signs of life until researchers thawed it out. Then, it ...

Researchers have discovered the first in-situ evidence of chlorophyll remnants in a billion-year-old multicellular algal microfossil preserved in shales from the Congo Basin. This discovery has made ...

New studies by the Max Planck Institute for Evolutionary Biology show that competition between different evolutionary developmental stages of multicellular life cycles can be important for the ...

There are photosynthetic bacteria known as cyanobacteria, and these microbes helped generate the oxygen that paved the way ...

Add Yahoo as a preferred source to see more of our stories on Google. The mystery of how multicellular life evolved has long baffled scientists, who've spent years trying to understand how solitary ...

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 ...

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 ...

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 ...
