Did ancient China and other Old World civilizations reach America before Columbus? Pioneering archaeologist and anthropologist Alice Beck Kehoe, Ph.D., examines the controversial evidence for pre-Columbian culture contact, trans-Pacific voyages, and connections between the ancient Old World and New World.Kehoe reflects on her boundary-breaking career, including decades of work with Indigenous communities and her role as an early voice in Feminist Archaeology. She explains how academic gatekeeping and archaeology’s “fortress mentality” can determine which theories are seriously investigated—and why researchers who challenge accepted history often face professional resistance.The conversation explores ancient seafaring, possible contact between Asia and Mesoamerica, and theories involving the Olmec and Maya. Kehoe also considers the Newport Tower, Kensington Runestone, wheeled toys found in Mesoamerica, Old World animal imagery, and other archaeological mysteries that have fueled debate over who may have reached America before Columbus.The episode also examines Viking and Norse exploration, ancient China, cultural diffusion, and whether ideas and technologies could have traveled across the oceans in both directions. Rather than relying on one artifact as definitive proof, Kehoe argues that archaeology should remain open to cumulative evidence and the possibility of a more interconnected ancient world.Alice Beck Kehoe is the author of Traveling Prehistoric Seas: Critical Thinking on Ancient Transoceanic Voyages.Subscribe to UnderGround for more evidence-based archaeology and ancient mysteries that challenge conventional narratives!#Archaeology#BeforeColumbus#PreColumbian#AncientChina#Mesoamerica #AncientHistory
