The Denisovans — an archaic hominin group identified in 2010 from ~41,000-year-old fossils found in Denisova Cave (Altai Mountains, Siberia) — left a striking and disproportionate genetic legacy in the populations of Isl
F_4_21 — Shared Flood Geology: Physical Evidence for Deluge Events
Flood myths appear in cultures across every inhabited continent — from the Sumerian/Akkadian flood (Ziusudra/Utnapishtim), the Hebrew Noah narrative, and the Greek Deucalion, to the Hindu Manu, the Chinese Gun-Yu, the Az
F_4_18 — Roman Britain and Beyond: Provincial Connectivity
