Metal availability and the expanding network of microbial metabolisms in the Archaean eon

Microbial metabolisms depend on enzymes that contain trace metals. A synthesis of molecular and geochemical data shows that these metabolic pathways evolved alongside changing marine availability of trace metals during the Precambrian. Life is based on energy gained by electron-transfer processes; t...
