So, did miRNAs evolve independently in unicellular and multicellular organisms, or are C. reinhardtii miRNAs evolutionary intermediates?

How does multicellularity evolve? Scientists who study a family of green algae that includes unicellular Chlamydomonas and multicellular Volvox are beginning to find answers to this question.

A single bacterium consists of just one cell. Not all bacteria are harmful. There are different unicellular organisms and types of bacteria. Yeast are unicellular fungi. They are used by brewers ...

An organism discovered near Hawaii is intriguing researchers. Its behavior could significantly alter our understanding of the origins of multicellular life on Earth. Chromosphaera perkinsii, a ...

Although some lineages or clades are entirely unicellular or multicellular (e.g., lobose amoeba and the land plants, respectively), most contain a mixture of body plans such as the unicellular and ...

The first life forms to appear on Earth were unicellular, i.e., composed of a single cell, such as yeast or bacteria. Later, ...

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 ...

“Though Chromosphaera perkinsii is a unicellular species, this behaviour shows that multicellular coordination and differentiation processes are already present in the species, well before the ...
