Archaic green sea that triggered the evolution of oxygen-producing cyanobacteria *(Takashi Tsujino, Nagoya University, Japan)*

A new study, in which GFZ postdoc Yosuke Hoshino (now at Nagoya University) was involved, and which was recently published in Nature Ecology and Evolution, suggests that green light prevailed in the underwater world of the Archaikum, which was crucial for the development of the first oxygen-producing photosynthesis on Earth – which used a unique pigment called phycobilin.
