Cyanobacteria use both chlorophylls and phycobilins to absorb light energy, and authors here use cultivation experiments, numerical simulations and protein phylogenetics to argue that cyanobacteria evolved in a green-light environment during the Archaean era in which green-specialized phycobilins would have been selectively advantageous.
