Researchers at the Max Planck Institute for Biology, Germany, have discovered a conserved developmental pattern known as the hourglass model in brown algae, providing more evidence that the phenomenon ...

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

In the beginning there were single cells. Today, many millions of years later, most plants, animals, fungi, and algae are composed of multiple cells that work collaboratively as a single being.

One of the most pivotal steps in evolution -- the transition from unicellular to multicellular organisms -- may not have required as much retooling as commonly believed, scientists have found. A ...

If you know anything about deep history, you’ve doubtless heard something about the Cambrian Explosion, 542 million years ago (MYA), when all those trilobites showed up with their animal body plans.

One of the big evolutionary questions in life is how and why single cell organisms organized themselves to live in a group, thereby forming multicellular life forms. Scientists have answered at least ...

A single-celled alga has evolved a crude form of multicellularity in the lab – a configuration it never adopts in nature – giving researchers a chance to replay one of life’s most important ...

An interview with the developmental biologist Cassandra Extavour on the origins of multicellular organisms and the evolution of cooperation. The developmental biologist Cassandra Extavour sings ...

LA JOLLA, CA-One of the most pivotal steps in evolution-the transition from unicellular to multicellular organisms-may not have required as much retooling as commonly believed, found a globe-spanning ...
