Overall, this study presents observations related to slime-mediated motility on multiple scales (molecular, single-filament and colony), and integrates these findings into a coherent model for the relationship between the cellular organization and the behavior of the colony.
The authors state that supracellular structures emerge from unordered motion and are therefore not encoded for genetically. While their model for spiral formation does not require a genetic program for controlling motility, it may not always be the case for other supercellular structures. In other words, it may not always be true that supercellular structures are not genetically determined.
