New Discovery Reveals the Secret Lives of Denisovans
Summary
This episode explores a major archaeological discovery at Bianfu Cave in southwest China, revealing that Denisovans inhabited the region for over 100,000 years. Guest Mike Marshall discusses how thousands of recovered artifacts and animal bones provide the first detailed insight into Denisovan lifestyle, hunting strategies, and tool use. The hosts also examine the genetic similarities between Denisovans, Neanderthals, and modern humans, challenging notions of human exceptionalism and exploring how interbreeding shaped our ancestry.
