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

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 ...

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

For some three billion years, unicellular organisms ruled Earth. Then, around one billion years ago, a new chapter of life began. Early attempts at team living began to stick, paving the way for the ...

Chromosphaera perkinsii is a single-celled species discovered in 2017 in marine sediments around Hawaii. The first signs of its presence on Earth have been dated at over a billion years, well before ...

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 ...

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 ...

A deep dive into macroalgae genetics has uncovered the genetic underpinnings that enabled macroalgae, or “seaweed,” to evolve multicellularity. Three lineages of macroalgae developed multicellularity ...

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 ...
