Working out how photosynthesis evolved.

"The most recently identified Gloeobacteria species, Anthocerotibacter panamensis, harvests light using a different set of proteins than modern cyanobacteria — but converts sunlight into chemical energy within protein complexes that vary only slightly from those in other Gloeobacteria. These traits add new color to the long, strange evolutionary story of photosynthesis."
