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

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 ...

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 ...

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 ...

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 ...

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 ...

At some point, organisms changed and grew from a single cell into one made up of many cells. But how that happened is not well understood. New work by graduate candidate Jonathan Featherston of 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 ...

Marine bacteria normally seen as single cells join together as a “microscopic snow globe” to consume bulky floating carbohydrates. Close your eyes and imagine bacteria. Perhaps you’re picturing our ...

Although bacteria may form colonies and biofilms, they do not constitute multicellular lifeforms like, well, us. Bacteria lack the ability to coordinate the basics of multicellularity, which include ...

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 ...
