Eminent prehistorian ANDREW COLLINS is our guest to discuss the debut of his book "Denisovan Origins," which he coauthored with our frequent other eminent prehistorian guest Dr. Greg Little. The Densiovans peoples are a recent archaeological discovery though they thrived in deep Antiquity, and we only have a few skeletal remains found in Siberia. However, Andrew and Greg piece together their ancestry and legacy from osteological remains unearthed over the last 140 years. Was this culture highly advanced, deeply spiritual and spreading their influence across the higher latitudes? Do we find evidence of their teachings in North America and at Gobekli Tepe? This interview will be a profound exploration of a historical mystery.
