Images of the multicellular development of the ichthyosporean Chromosphaera perkinsii, a close cousin of animals. In red, the membranes and in blue the nuclei with their DNA. The image was obtained ...

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 ...

Archaea—one of the three primary domains of life alongside bacteria and eukaryotes—are often overlooked and sometimes mistaken for bacteria due to their single-celled nature and lack of a nucleus. Yet ...

Some single-celled organisms are known to transition to multicellularity during their lifetimes, usually either by cloning themselves or when many similar cells come together to form a larger ...

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

The world is full of unusual unicellular organisms and microbes, many of which have not been discovered yet. In 2017, scientists identified a single-celled marine organism called Chromosphaera ...

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 ...

Multicellular cyanobacteria do something strikingly sophisticated with their DNA, toggling key genes on and off as day turns to night so different cells can specialize without starving the colony of ...

Marine bacteria normally seen as single cells join together as a “microscopic snow globe” to consume bulky floating carbohydrates. Close your eyes and imagine bacteria. Perhaps you’re picturing our ...

Scientists have discovered the fossil of what may be the earliest multicellular animal ever found. Dating back a billion years, the microscopic fossil contains two distinct cell types, potentially ...
