Before UsGoing with the FlowSend us a textThere is unambiguous agreement that early humans had to cross open water when they traveled from Sundaland to Sahul before 40,000 years ago. How were they able to do this and would ocean winds and currents have helped or hindered their voyages? In this episode we talk to Kiki Kuijjer and Bob Marsh, both from the University of Southampton, about flow modeling that potentially reveals how humans may have been able to make their fantastical journeys.

Understanding these processes is crucial for studying prehistory in deep time, including human migration from Sundaland to Sahul and the movement of people around the globe. In this episode, Justin Dix breaks down what drives sea level change, how scientists reconstruct past sea levels, and how these fluctuations have shaped human history.

This ambitious project dives into oceanographic, geoscience, archaeological, and archaeogenetic data to figure out when and how people first made the journey to Sahul, what routes they might’ve taken, and just how long they were stuck in a boat. Spoiler: it wasn’t a weekend trip. These early voyages don’t just tell us about getting to Sahul—they also help us understand...2025-04-0820 minBefore UsHooked from the startSend us a textThe rapid dispersal of modern humans across Wallacea to modern day Australia not only required boat technology for long-distance sea travel, but also knowledge about deep-sea fishing. In this episode, we talk to Sue O’Connor about the different routes that people may have taken across Wallacea in the Pleistocene and how the different kinds of islands on those routes may have influenced maritime resource use and the earliest evidence of pelagic fishing.

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 People2025-03-1831 minBefore UsNot just wanderers, also wonderersSend 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 Gamble2025-03-1126 minBefore UsIn deep time, in deeper watersSend 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.2025-03-0429 minBefore UsWaves of ChangeSend 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 th...2025-02-2528 minBefore UsThe Omega-th wonder of the worldSend us a textHave you ever wondered how aquatic foods shaped human evolution? In this episode, we dive into the fascinating role of seafood in our development with world-renowned experts Michael Crawford and Stephen Cunnane. As leading researchers in brain-selective nutrition, they explore how iodine, fatty acids, and other essential nutrients have influenced modern human health—and their profound impact on our evolutionary journey.

They were also the first to control and use fire. In this episode, we speak with Josephine Joordens and Irit Zohar to explore these early time periods, approximately 2 million years ago. We delve into when and how hominins first developed an interest in aquatic resources, the transformative impact of cooking fish, and why a stable, year-round food source like fish was crucial for hominin survival and their dispersal across the globe.2025-02-1123 minBefore UsHead over heels for aquatic environmentsSend us a textArchaeology tells the story of people, yet identifying individuals in the archaeological record remains notoriously challenging. In this episode, we speak with Rachel Bynoe, Charles Helm, and three Ju/’hoansi master trackers - /ui Kxunta, ≠oma Daqm, and /uce Nǂamce - from Nyae Nyae, Namibia, to explore ichnology—the study of tracks and traces.
