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 ...

Throughout the history of life on Earth, multicellular life evolved from single cells numerous times, but explaining how this happened is one of the major evolutionary puzzles of our time. However, ...

If you look at the world around you now - at the plants, animals, and the people around you, it's easy to take for granted our multicellular existence. Life didn't always look like this. In fact, way ...

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 ...

Scaling up from one cell to many may have been a small step rather than a giant leap for early life on Earth. A single-celled organism closely related to animals controls its life cycle using a ...

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 ...

At some point, organisms changed and grew from a single cell into one made up of many cells. But how that happened is not well understood. New work by graduate candidate Jonathan Featherston of the ...

How low can worms go? According to a new study, at least 0.8 miles (1.3 kilometers) below the Earth's surface. That's the depth at which scientists discovered a new species of worm, dubbed ...

The genome sequencing of the algae, Gonium pectorale, provides valuable clues into how and why single cells live together in groups -- one of the earliest steps on the path to a multicellular ...
