Why did multicellularity arise? Solving that mystery may help pinpoint life on other planets and explain the vast diversity and complexity seen on Earth today, from sea sponges to redwoods to human ...

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 ...

MicroRNAs (miRNAs) — a class of small RNAs with a role in the regulation of gene expression — had until now been found only in multicellular organisms. Now, Wang, Qi and colleagues provide the first ...

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 ...

Unicellular organisms show surprising complexity In a paper appearing in Nature Genetics, researchers discover that in more "primitive" unicellular organisms, both the adenine and the cytosine bases ...

How do living organisms that lack a brain or nerve cells make decisions? In a new study published in May 2021 in the Proceedings of the National Academy of Sciences of the United States of America ...
