When subjected to physical pressure, archaea - ancient single-celled organisms - form multicellular structures.

The first life forms to appear on Earth were unicellular, i.e., composed of a single cell, such as yeast or bacteria. Later, animals—multicellular organisms—evolved, developing from a single ...

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 ...

Archaea—one of the three primary domains of life alongside bacteria and eukaryotes—are often overlooked and sometimes ...

Cells are microscopic building blocks of unicellular and multicellular living organisms. Animal, plant, fungal and bacterial cells are different in terms of structure but also have many similarities.

In fact, why and how multicellular life evolved has long ... a relatively giant unicellular organism, the report is published in Nature Physics. "We took a step back in evolution, to when ...

Shown are representatives of all major lineages of eukaryotic organisms ... lineages composed entirely of unicellular species. Other groups shown contain only multicellular species (solid red ...

The physics of how a quirky pond organism filters the water for food provides new insights into a possible driver of early evolution.

Unicellular and multicellular organisms must control their metabolism in order to survive. Metabolic rates can vary depending on physiological states. The circulatory system and respiratory system ...

after obtaining evidence that the fluid dynamics of cooperative feeding among unicellular organisms could have been the driving force behind the evolution of multicellular life. "We took a step ...

The study is based on the fluid dynamics of cooperative feeding by Stentor, a relatively giant unicellular organism. Humans like to think that being multicellular (and bigger) is a definite ...
