What do choanoflagellates tell us about the evolution of multicellularity?

Early multicellular organisms did not require adhesion proteins

The first multicellular animals made use of pre-existing adhesion proteins to form feeding aggregations

The first multicellular aggregations were probably favored as a defense mechanism against predatory bacteria, which favored larger and larger aggregations
