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 ...

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 ...

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 ...

Over 3,000 generations of laboratory evolution, researchers watched as their model organism, 'snowflake yeast,' began to adapt as multicellular individuals. In new research, the team shows how ...

A major event in the evolution of organisms on earth was the development of complex, multicellular life forms made of eukaryotic cells, which are thought to have come from prokaryotic cells. Studies ...

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, ...

The discovery of a billion-year-old fossil in Scotland offers exciting new insight into animal evolution, BC researcher says Loch Torridon in Scotland, where the microfossil was discovered. Photo: ...

This is a preview. Log in through your library . Abstract The evolution of complex multicellularity has been one of the major transitions in the history of life. In contrast to simple multicellular ...
