An illustration of a choanoflagellate. Researchers have discovered that these single-cell organisms are unique in that they contain molecules that cells in multi-cellular organisms use to communicate with each other. These findings provide new insights into how multi-cellular organisms evolved and they suggest other uses for these communication molecules that have yet to be discovered.
