When the slime mold Dictyostelium discoideum runs out of food, sulfur limitation drives its development from a unicellular to a multicellular organism. Researchers now present the nutrient signaling ...

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

Volvocine algae provide an excellent model for understanding the gradual evolution from unicellularity to complex multicellularity. Spanning a range of organization from simple unicellular forms to ...

That's why the scientists think their Stentor model precedes other models of early multicellularity (which is believed to have evolved at least 25 times in different lineages). "This is earlier, much ...

Scientists at Nagoya University in Japan have identified the genes that allow an organism to switch between living as single ...

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 ...

To understand the origins of multicelled life, researchers are studying a motley assortment of simpler animal relatives. The commonalities they’re unearthing offer a trove of clues about our mutual ...

Scientists believe multicellular organisms evolved from single celled life, but understanding how has been difficult. To finaly understand the process of evolution into multicellularity, researchers ...

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 ...

Evolved macroscopic "snowflake" yeast from the MuLTEE experiment. The large size of the nuclei (yellow) and cells (cyan) are results of whole-genome duplication and aneuploidy. Sometimes, the most ...

The evolutionary transition to multicellularity probably began with the formation of simple undifferentiated cellular groups. Such groups evolve readily in diverse lineages of extant unicellular taxa, ...
