Stentor coeruleus is a giant unicellular, filter-feeding protist that uses the coordinated motion of its oral ciliary structure to generate feeding currents. These currents allow the organism to ...

Oxygen played a key role in the evolution of complex organisms, according to new research published in BMC Evolutionary Biology. The study shows that the complexity of life forms increased earlier ...

Scientists in Japan have discovered a previously unknown giant virus, offering new insight into this enigmatic category of ...

Life on Earth began in a way that still boggles the mind. Around 4.5 billion years ago, a chemical process called abiogenesis ...

In a groundbreaking experiment, researchers have brought a mouse to life with the help of a single-celled organism that existed long before any multicellular animals walked the earth. Genetic research ...

Life emerged on Earth some 3.8 billion years ago. The “primordial soup theory” proposes that chemicals floating in pools of water, in the presence of sunlight and electrical discharge, spontaneously ...

Foreword : the evolution of multicellularity / John Tyler Bonner -- I. Functional and molecular predispositions to multicellularity. Fossils, feeding, and the evolution of complex multicellularity / ...

A study presents a striking example of cooperative organization among cells as a potential force in the evolution of multicellular life. The study is based on the fluid dynamics of cooperative feeding ...

WOODS HOLE, Mass. -- Humans like to think that being multicellular (and bigger) is a definite advantage, even though 80 percent of life on Earth consists of single-celled organisms – some thriving in ...
