"It's hard to understand how lots of different shadow biospheres would be a stable system and not about competing each other well maybe it could be stable in the same sense that we have multiple species now," he says. "Once you've got one origin of life that has spread around the world it basically closes the door on any further origins of life from primitive simple biochemistry because an origin of like Darwin's conan origin of life lying around all you're describing now is just a tasty soup for a subtle look that encounters it right"

I interview award-winning astrobiologist and science writer Lewis Dartnell. We discuss themes from his most recent book, Origins: How The Earth Made Us, as well as ideas from his field of study, astrobiology. Dr. Dartnell holds the Professorship in Science Communication at the University of Westminster. Interview topics include: how the Earth's cycles may have driven human evolution, humanity's search for extraterrestrial life, the shadow biosphere, why some civilizations came to dominate the globe, and more.
