Some microbes used poison gas in battle for iron in the Earth's early oceans, geomicrobiologists find
Early in the Earth's development, the atmosphere contained no oxygen. Yet the iron dissolved in the oceans was oxidized in gigantic quantities and deposited as rock. It can be seen today, for example, as banded iron ore in ...
