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 ...

We've heard a lot about how important carbon and water are to life, but sulfur? Researchers think that sulfur may have actually been essential for organisms to make the transition from single-celled ...

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

The world would look very different without multicellular organisms – take away the plants, animals, fungi, and seaweed, and Earth starts to look like a wetter, greener version of Mars. But precisely ...

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 ...

The mystery of how multicellular life evolved has long baffled scientists, who've spent years trying to understand how solitary single-celled organisms began living in unison and triggered the ...

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 ...

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

Cooperation is a classic solution to hostile environments that limit individual survival. In extreme cases this may lead to the evolution of new types of biological individuals (e.g., eusocial ...

Cells can evolve specialized functions under a much broader range of conditions than previously thought, according to a study. Cells can evolve specialised functions under a much broader range of ...

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 ...
