The wakes we inherit

In this episode we explore the ecology of the North Pacific Rim with Jon Erlandson, and specifically, the idea that kelp ecosystems may have acted much like a highway into the Americas, providing early coastal and maritime hunter-gatherers with familiar, dense, and predictable resources almost continuously from Japan all the way to the southern tip of South America**Please do not forget to rate and review the show** Have a question or comment? Email: [email protected]: https://www.reddit.com/r/BeforeUsMedia/Or click “Send us a message!” at the top of this page. Key IdeasCoastal Migration HypothesisKelp Highway Hypothesis Key PeopleJon Erlandson Key PlacesDaisy CaveChannel IslandsManis Mastodon SiteGault SiteDebra L.

How do you test how people reached Okinawa more than 30,000 years ago? Build a log boat using only Paleolithic stone tools, then paddle it from Taiwan to the Ryukyu Islands. This week, we talk to Prof. Yousuke Kaifu about the extraordinary project he led to explore how prehistoric people could have made a voyage that, even today, seems improbable. It’s a fascinating discussion about their trials-and-errors to build a boat that could handle the open ocean and their journey to cross one of the world’s biggest ocean currents.  **Please do not forget to rate and review the show** Have a question or comment? Email: [email protected]: https://www.reddit.com/r/BeforeUsMedia/Or click “Send us a message!” at the top of this page. Key People and ProjectsYousuke KaifuHolistic Reenactment Project WebsiteThe University Museum, The University of TokyoKey PlacesTaiwanYonaguni IslandRyukyu Island ChainKuroshio Current   Further ReadingChang, Y.L.K., Miyazawa, Y., Guo, X., Varlamov, S., Yang, H. and Kaifu, Y., 2025.

We're taking a small detour this week to talk about the role of voyaging and the embodied knowledge of seafaring that has been collected and passed down for generations among modern communities all across the Pacific.  It's a perspective that isn't so much about the past rather than how the past shapes the present and future. **Please do not forget to rate and review the show**Have a question or comment? Email: [email protected]: https://www.reddit.com/r/BeforeUsMedia/Or click “Send us a message!” at the top of this page. Key PeopleH.

Fossil and genetic evidence shows that eastern Asia was a hotspot of diversity for the genus Homo during the Middle and Late Pleistocene. Homo erectus, Denisovans (Homo longi and Homo juluensis) / Neanderthals, Homo floresiensis, and Homo Luzonensis were all present at one point or another. But when did modern humans arrive from Africa? In this episode, we talk to Fabrice Demeter about excavations at Tam Pa Ling cave in Laos, where his team has uncovered a rich fossil record documenting some of the earliest known modern humans in Southeast Asia. These discoveries place modern humans in the region as early as 86,000 years ago, with further evidence of their presence until around 54,000 years ago. Yet these early arrivals may have been part of a dispersal that ultimately failed, leaving little, if any, genetic trace in present-day populations. **Please do not forget to rate and review the show** Have a question or comment? Email: [email protected]: https://www.reddit.com/r/BeforeUsMedia/Or click “Send us a message!” at the top of this page. Key PeopleDr. Fabrice Demeter Key PlacesTam Pa LingTam HangTam Ngu Hao 2 Key SpeciesHomo sapiensHomo erectusDenisovansHomo juluensisHomo longi Further ReadingDemeter, Fabrice, Clément Zanolli, Kira E.

Asia plays a central role in the story of human evolution and recent cutting-edge research shows that eastern Asia was home to a variety of archaic human species that were still present by the time modern humans arrived during the late Pleistocene. In this episode, Prof. Christopher Bae leads us on a fascinating journey of the paleoanthropology and archaeology of eastern Asia to understand the complex biogeographic landscape that greeted those earliest modern humans. **Please do not forget to rate and review the show**Have a question or comment? Email: [email protected]: https://www.reddit.com/r/BeforeUsMedia/Or click “Send us a message!” at the top of this page. Key PeopleProf. Christopher Bae Key PlacesXujiayaoXujiangHarbinDenisova CaveHuanglong (Hualongdong) Cave Key SpeciesHomo erectusDenisovansHomo juluensisHomo longi Further ReadingBae, Christopher. The Paleoanthropology of Eastern Asia.

As modern humans spread across the world along coastlines and waterways during the Late Pleistocene, they encountered a remarkable variety of coastal environments, each with its own resources and challenges. In this episode, we explore one of the seemingly least hospitable coastal environments: maritime deserts. We discuss Boodie Cave on Barrow Island, off Australia’s northwest coast, with Tiina Manne from the University of Queensland to discover how people adapted their knowledge to this demanding environment and thrived there for tens of thousands of years.**Please do not forget to rate and review the show!**Have a question or comment? Email: [email protected]: https://www.reddit.com/r/BeforeUsMedia/Or click “Send us a message!” at the top of this page. Key PeopleTiina ManneKey PlacesBoodie CaveBarrow IslandFurther ReadingWard, Ingrid, et al.

As modern humans spread across the world at the end of the Pleistocene, they learned to survive in a remarkable range of environments. How did those hunter-gatherers preserve their knowledge and pass it on from one generation to the next? In this episode, Helen and Erich speak with Patrick Nunn to explore the role of oral history, myths, and storytelling in the preservation of knowledge among preliterate societies.  Welcome back to a new season of Before Us! **Please do not forget to rate and review the show!**Have a question or comment? Email: [email protected]: https://www.reddit.com/r/BeforeUsMedia/Or click “Send us a message!” at the top of this page. Key PeoplePatrick NunnKey PlacesBackstairs PassagePentecost Island, Vanuatu Further ReadingNunn, Patrick. Whispers from Celtic seas: the true meanings of ancient stories from Northwest Europe.

A new season of Before Us premieres Tuesday, September 29, 2026! Join us as we  as we explore the remarkable human story behind the world we know today. We are continuing to explore humanity’s enduring relationship with aquatic resources and how coastlines and waterways helped shape our remarkable expansion worldwide. This season, we follow the movement of modern humans through Southeast and East Asia, around the North Pacific Rim, and into North and South America, uncovering the epic story of the Peopling of the Americas. This season will be bigger and more amazing than ever before. We've lined up leading scientists and communities from around the world to provide the most current insights on archaeology, genetics, linguistics, mythology, dog domestication, skin-boat technology, and so more. If you enjoy this show then don’t forget to rate and review us!
