Green oceans on early Earth, shaped by iron, pushed microbes to evolve light-absorbing tools that worked in green light.

A new study suggests Earth's oceans may have been green during the Archean eon, around 3.8 to 1.8 billion years ago. The greenish hue was due to high iron content and early microbes performing ...

This iron will become important later. The Archaean eon was a time when Earth's atmosphere and ocean were devoid of gaseous oxygen, but also when the first organisms to generate energy from ...

suggests that during the Archaean era, around 2.4 billion years ago, Earth’s oceans were likely bathed in green light, a discovery that helps explain how early life evolved in such an environment.

Other sources of iron were volcanoes on the ocean floor. This iron became important later. The Archaean eon was a time when Earth’s atmosphere and ocean were devoid of gaseous oxygen, but also when ...
