Researchers from Nagoya University explored how cyanobacteria, among the first photosynthetic organisms, influenced the color of Archean oceans. Their work, published in Nature Ecology & Evolution ...

As these cyanobacteria thrived ... simulations and discovered green light dominated the spectrum during the Archean eon, primarily due to a process called iron precipitation.

With the rise of cyanobacteria—key players in Earth ... estimate how light filtered through Earth’s oceans during the Archean era, 4–2.5 billion years ago. Their findings suggest that ...

because there are other independent lines of evidence that oxygenic photosynthesis and hence cyanobacteria first evolved during the Archean eon," Buick added. "However, the scarcity of well ...

Tajika and his team used a numerical model to simulate key aspects of biological, geological and chemical changes during the late Archean eon (3.0-2.5 billion years ago) of Earth's geologic history.

But dig a little deeper, and things get even weirder. In a surprise to scientists, cyanobacteria have been found thriving nearly 2,000 feet below the strange landscape, where sunlight, water ...
