The late Neoproterozoic witnessed remarkable changes in almost all envelopes of the planet. The biosphere experienced one of its most fundamental evolutionary steps with the rise of complex life forms, which was accompanied by fundamental changes in oceanic deep-water redox conditions, fluctuations between extreme climate modes, and major changes in the configuration of continents. In this context, links between biological innovation and environmental changes are usually implied, but we know little about the relative roles of environmental and biological factors, their effects, and feedbacks involved in the late Neoproterozoic events leading to the ultimate oxygenation of the ocean-atmosphere system and dawn of animal life. We intend to fill these gaps by integrating five sub-projects: (1) a high-resolution sedimentological and geochronological work on four key areas in Brazil and Africa, (2) detailed investigation of the paleontological record on these four successions, and examination of the physiology, ecology and developmental behavior of early metazoans to verify connections between changes in ocean redox and composition with life evolution, (3) a multiple-proxy study of the four sedimentary successions, (4) reconstruction of the still poorly resolved late Neoproterozoic paleogeography, including the magnitude of mountain chains, that represents a key element in climatic and paleoceanographic reconstructions, (5) numerical modelling of the climate-ocean system and biogeochemical cycles in a well-constrained paleogeographic context. The overall objective of the proposal is to understand the controlling role of environmental forcings, in particular the rise of atmospheric oxygen and nutrient availability, on the origin of the metazoan ecosystem and related feedbacks between life, environment and tectonics at the advent of the modern Earth.
