It's time to look at fossil dating again!  The last episode mentioned two dating methods used to estimate how old the Homo Naledi bones found the Rising Star cave system might be. To do so, researchers used a Uranium-thorium method as well as electron spin resonance, or “ESR”.  Let's take a brief look at what each of these entail.  For show notes and more, please visit https://EvolutionTalk.com Written, Produced, & Narrated by: Rick Coste

            The concept of superposition exists in both quantum mechanics and evolutionary geology. We start with the strange and counterintuitive world of quantum physics, where particles exist in multiple states until observed. Then, we journey back to 1666 where another kind of superpositionwas discovered—this time in rock layers - allowing us to read Earth's history through its geological layers.  Please consider becoming a show Patron to help keep new episodes coming!               Evolution Talk is also a book!

The Law of Superposition

            What if consciousness, much like the architectural 'spandrels' we talked about before, isn't actually crucial to our survival? Stephen Jay Gould and Richard Lewontin argued that some traits might just be byproducts, not directly selected for their utility. We'll unravel this thread by retracing the steps of René Descartes on a cold night in 1619 when he conceived ideas that challenged our understanding of reality. Was his revelation in a cozy 'oven' room the birth of modern philosophy, or a deeper insight into the illusions crafted by our own minds? Descartes' meditations prompted us to doubt our senses and the very nature of reality, suggesting that maybe, just maybe, our lives are nothing but elaborate deceptions.  Please consider becoming a show Patron to help keep new episodes coming!               Evolution Talk is also a book!
