It has been widely assumed that, in single-celled organisms, each cell perceives its environment -- and responds to stress conditions -- individually. Likewise, it had been thought that cells in ...

All multicellular creatures are descended from single-celled organisms. The leap from unicellularity to multicellularity is possible only if the originally independent cells collaborate. So-called ...

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 ...

One of the biggest evolutionary hurdles for life on Earth was the jump from single-celled to multi-cellular organisms…or at least, that’s what we thought. Scientists set out to replicate this ...

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, ...

Scientists study ancient unicellular organism C. perkinsii to understand transition from single-cell to multicellular life. Research suggests C. perkinsii demonstrates early forms of multicellular ...

A new study by researchers at the University of Queensland is calling old ideas about evolution into question. The scientists used powerful genetic technologies to sequence every gene being expressed ...

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 ...

Compressing a type of single-celled microorganism makes it develop into a multicellular tissue-like structure with different cell types. This suggests that pressure can help drive key evolutionary ...
