When did life evolve? What were the first cells like? Can we trace connections between major innovations in microbial cell structure or biochemistry and dramatic changes in atmospheric composition and global climate, e.g. global warming and near-global freezing (snowball earth) episodes?

Leading earth scientists and biologists will discuss multidisciplinary evidence for the historical interplay of cell evolution and earth history.
