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

The evolution of multicellularity enabled specialization of cells, but required novel signalling mechanisms for regulating cell differentiation. Early multicellular organisms are mostly extinct and ...

Ancient body blueprint: Sea anemones use a BMP shuttling mechanism to form their back-to-belly axis, a process shared with distant bilaterian animals. Sticking together: UChicago research shows early ...

Researchers in the Wallace H. Coulter Department of Biomedical Engineering at Georgia Tech and Emory University have uncovered something new in one of the most studied organisms on Earth, and their ...

Animals, from worms and sponges to jellyfish and whales, contain anywhere from a few thousand to tens of trillions of nearly genetically identical cells. Depending on the organism, these cells arrange ...

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 ...

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 ...

The transition from single-celled to multicellular organisms was one of the most significant developments in the history of life on Earth. Without it, all living things would still be microscopic and ...

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.

Interpreting truly ancient fossils is an especially tricky business. The conclusion that 2.1-billion-year-old structures from Gabon are the remains of large colonial organisms will get ...

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 ...
