Summary

Story summary

A study from the Max Planck Institute for Evolutionary Biology shows Pseudomonas fluorescens forming mat-like structures at the air-liquid interface, published in Proceedings of the Royal Society B.
The ancestral type's role in facilitating this process is identified.
The interface is transiently colonized and supports mat-forming mutants.
The study emphasizes a dispersal-driven model that favors genetic diversity over a single dominant type.
