【 摘 要 】

The evolution of life on earth has been a long process that began nearly 3.5 × 10⁹ years ago. In their initial moments, evolution was mainly influenced by anaerobic environments; with the rise of O₂ and the corresponding change in bioavailability of metal ions, new mechanisms of survival were created. Here we review the relationships between ancient atmospheric conditions, metal ion bioavailability and adaptation of metals homeostasis during early evolution. A general picture linking geochemistry, biochemistry and homeostasis is supported by the reviewed literature and is further illustrated in this report using simple database searches.
