Public Science Lectures: 10/19/ 10 The Evolution of Photosynthesis

Prof. Tanja Bosak and Alexander Petroff of the Bosak Lab, Dept of Earth, Atmospheric and Planetary Sciences discuss how scientists reconstruct the evolution of photosynthesis by field research and lab experiment. This presentation is an excellent explanation of how scientists work to understand very ancient processes on Earth, and the challenge of reconstructing natural processes that occurred billions of years ago.
