The evolution of life and Earth's habitats in the Precambrian World is best understood via an integrated analysis of the lithosphere, atmosphere, hydrosphere and biosphere. For instance, the redox volution and the geodynamical evolution during Precambrian times played
a fundamental role in shaping ancient environments. In this session we invite contributions from combined fields of sedimentology,(bio)geochemistry, palaeogeography and plate tectonics, numerical modelling, palaeontology and geophysics. We will explore key events in Earth's history from the Archean to the Ediacaran, including the origin
of life and the Snowball Earth events and beyond. We discuss the (co-)evolution of the atmosphere, biosphere and oceans and also try to understand how much better the Neoproterozoic glaciations are constrained and understood since the advent of the snowball Earth hypothesis over the last 20 years.

This session is affiliated with IGCP 648, Supercontinent Cycles and Global Geodynamics.
