The relative role that environmental versus intrinsic biological factors played in
shaping the history of life on Earth is a fundamental but unanswered question in the
natural sciences. Most famously, it has been heavily debated if the emergence and
diversification of early animals during the Ediacaran Period (ca. 635–541 Ma) was tied to
a rise in atmospheric-oceanic oxygen levels. Temporally discontinuous geochemical data and patchy fossil record in literature are inadequate to chart the Ediacaran redox history and its causal relationship with the biotic evolution. My PhD study aims for a multiproxy geochemical record within a well-established stratigraphic framework of …
