We live in a solar-powered world. Photosynthesis is the process by which some organisms (notably plants and cyanobacteria) harness the energy of sunlight to power their own metabolism, in the process creating the sugars (food) which provide a source of energy for all sorts of other organisms, not to mention releasing oxygen as well. Photosynthesis is the reason our planet is the way it is, from the diversity of life to the composition of the atmosphere. In this episode, we discuss the diversity of photosynthesis and photosynthesizers, what we know about the evolutionary history of the process, and how it has profoundly changed the world.
In the news: freshwater plesiosaurs, endothermy evolution, whale shark diets, and bone-crushing dogs.
