Episode 158 of the Rock Art Podcast steps beyond rock art to explore “obsidian conveyance systems”—how volcanic glass moved through travel, trade, and social ties, and what that reveals about prehistoric lifeways. Host Dr. Alan Garfinkel is joined by co-host Chris Webster for a conversation on obsidian sourcing, chemical fingerprints, and why big datasets can reconstruct connections even when stratigraphy is mixed. Alan draws from a major post-wildfire cultural project in southern Oregon’s North Umpqua River Basin, where cleared forests exposed dense artifact scatters and a surprising pattern: heavy reliance on obsidian despite sources 100+ miles away, including biface caches dated to around 4,000 years ago.

In this episode, Alan is joined by Dr. Maria Guagnin (Max Planck Institute for Geoanthropology) and Dr. Ceri Shipton (Australian National University) to explore how human societies adapted to environmental change during the Pleistocene–Holocene transition. Maria and Ceri examine prehistoric settlement, mobility, and monumental rock art in northern Arabia, showing how symbolic expression and landscape use offer insight into survival, innovation, and cultural continuity. Their research demonstrates the resilience and creativity of early human societies.

As the APN takes a break this holiday season we are taking this opportunity to make you aware of other great shows on the network. This episode is from the Ethnocynology Podcast with David Ian Howe.

Ethnocynology Podcast Ep 15: Direwolf Science with Dr. Shield-Chief Gover

In this episode of Ethnocynology, David chats with friend, colleague, and former A Life in Ruins host, Dr. Carlton Shield Chief Gover.

David and Carlton do a brief catch up before diving right into the recent paper released by Colossal Biosciences and a team of researchers regarding newly researched direwolf genetics.

David and Carlton discuss the ethics of release the un-peer reviewed paper only after the huge media push, as well as Carlton gives a an analysis of the statistics in the paper.
