Summary: As humanity continues to ponder its existence, 'where did we all come from? Why are we here?', researchers have suggested we may be asking the wrong questions in trying to uncover the answers. This episode we explore our evolving understanding of photosynthesis, and why the answers to some of our biggest philosophical questions could be locked in the process that enabled life to inhabit the planet, rather than what birthed us. Speakers: David Suggett - Associate Professor in the Climate Change Cluster at the University of Technology Sydney. Tim Gibson - PhD Candidate in the Department of Earth and Planetary Sciences at McGill University, Canada. Dr Robin Purchase from the Research School of Chemistry at the Australian National University. Producer: Jake Morcom.
