Fluctuating sunlight poses a challenge for plants and green algae, which must quickly adjust their photosynthetic systems to remain efficient in changing conditions. Aiding in that response is a kind of rudimentary memory that allows these organisms to respond more rapidly to changes in light following previous fluctuations.

Proteins are the key players for virtually all molecular processes within the cell. To fulfill their diverse functions, they have to interact with other proteins. Such protein-protein interactions are mediated by highly complementary surfaces, which typically involve many amino acids that are positioned precisely to produce a tight, specific fit between two proteins. However, comparatively little is known about how such interactions are created during evolution.
