Reconstructed ancestral enzymes suggest long-term cooling of Earth’s photic zone since the Archean
Paleotemperatures inferred from the isotopic compositions (δ(18)O and δ(30)Si) of marine cherts suggest that Earth’s oceans cooled from 70 ± 15 °C in the Archean to the present ∼15 °C. This interpretation, however, has been subject to question due to uncertainties regarding oceanic isotopic composit...
