Send us a textThe discovery of Homo floresiensis and Homo luzonensis in SE Asia raises big questions about what happened to some early populations of migrants. Here, John McNabb, explains how these discoveries re-shape our understanding of human evolution and human migrations, but also what the world was like when modern humans began to expand out of Africa. It may have been much more crowded than previously thought!Key SiteLiang BuaMata mengeDmanisiKey PeopleJohn McNabb (Mac)Mike MorewoodKey HominidsHomo floresiensisHomo luzonensisHomo erectusDenisovanMore ReadingBrumm, A., van den Bergh, G., Storey, M. et al.

Not just wanderers, also wonderers
Send us a textWhy did humans migrate out of Africa? This question has long puzzled archaeologists. Were they driven by unknown pressures, drawn by opportunities, or was it something else entirely? Best-selling author and researcher Clive Gamble explores how curiosity may have fueled the human expansion out of Africa and how the development of the concept of 'containers' was crucial for technological innovations, such as boats.Key PeopleClive Gamble

In deep time, in deeper waters
Send us a textSea levels have risen and fallen repeatedly over the last 2 million years. During low sea levels, large tracts of land were exposed along coastlines around the world, creating new habitats for plants, animals, and people to inhabit and new routes for people to move around the world. Now, many of these places are underwater, but evidence of these ancient landscapes, and the people who occupied them, still exists. In this episode we chat with Geoff Bailey and Hayley Cawthra about the challenges of working in coastal environments and reconstructing their submerged stories.Key PeopleGeoff BaileyHayley CawthraAdditional resources 2021.

Waves of Change
Send us a textAround 170,000 years ago people living in sea caves on South Africa’s south coast were repeatedly collecting and eating shellfish from the nearby coastline. It marked an important behavioral shift from the occasional collection of aquatic resources to systematic relying on aquatic resources for survival. In this episode, travel to the UNESCO World Heritage Site of Pinnacle Point in South Africa to talk with Curtis Marean, one of the foremost experts on the origins and development of coastal foraging, about how the transition from opportunistic to systematic coastal foraging may have occurred and the unexpected impact that the shift to a true coastal adaptation may have had on the development of social cooperation.Key PeopleCurtis MareanKey PlacesPinnacle PointUNESCOMarean, Curtis W. 2016, The transition to foraging for dense and predictable resources and its impact on the evolution of modern humansPhil.

Every living person can trace their ancestry back to Africa, where modern humans evolved some 300,000 years ago before expanding out of Africa and around the world. Those early humans lived lives filled with emotions and challenges much like people today and their journeys stand as a testament to human intelligence, ingenuity, creativity, and resilience. But, what does the archaeological record tell us about their lives, their successes, their failures, and who we are today? In this podcast, world-recognized experts in maritime and prehistoric archaeology, Dr. Helen Farr and Dr. Erich Fisher, reveal the people and the world that existed “Before Us.” This season, we take a deep dive into the origins and development of Maritime Adaptations, tracing humanity's journey from the earliest interests in aquatic resources to the global expansion of modern humans via oceans, coastlines, and waterways. As the old saying goes, “smooth seas make boring stories” and this season promises to be an auditory adventure around the world and across millennia as told through captivating interviews with leading scholars in fun and down-to-earth discussions.
