On the co‐evolution of surface oxygen levels and animals
Few topics in geobiology have been as extensively debated as the role of Earth's
oxygenation in controlling when and why animals emerged and diversified. All currently …

Recurrent photic zone euxinia limited ocean oxygenation and animal evolution during the Ediacaran
Abstract The Ediacaran Period (~ 635–539 Ma) is marked by the emergence and
diversification of complex metazoans linked to ocean redox changes, but the processes and …

Global marine redox evolution from the late Neoproterozoic to the early Paleozoic constrained by the integration of Mo and U isotope records
The emergence and diversification of early animals is commonly thought to have coincided
with atmosphere and ocean oxygenation across the terminal Neoproterozoic and early …
