F_2_03 — Sub-Saharan African Maritime and Trade Networks
Sub-Saharan Africa was deeply integrated into global trade networks for millennia, challenging Eurocentric narratives that portray the continent as isolated before European colonization. The Indian Ocean dhow trade conne
F_2_05 — Amber, Incense, and Spice Routes: Pre-Silk Road Exchange Networks
Long before the Silk Road connected Han China to Rome, extensive networks of luxury exchange linked the Baltic to the Mediterranean, the Arabian Peninsula to Egypt, and South Asia to the ancient Near East. Baltic amber —
F_2_01 — Bronze Age Trade Networks
Bronze Age trade networks provide a documented, testable middle ground between independent invention and lost-civilization contact as explanations for shared cultural motifs across the ancient world. If tin from Cornwall
F_2_14 — Ancient Glass Bead Trade: From Mesopotamia to Sub-Saharan Africa
Glass beads are among the most archaeologically informative objects in the ancient world — small, durable, widely traded, and chemically distinctive — making them exceptional tracers of long-distance exchange networks sp
F_2_08 — Lapis Lazuli Trade Networks
Lapis lazuli — a deep-blue metamorphic rock composed primarily of lazurite — is one of the oldest traded luxury materials in human history, with its distribution across the ancient world providing direct evidence of long
F_2_18 — Ancient Trade in Aromatics: Frankincense, Myrrh, and Sacred Resins
Frankincense (Boswellia sacra and related species) and myrrh (Commiphora myrrha) — aromatic tree resins harvested from the arid landscapes of southern Arabia (Oman's Dhofar region, Yemen's Hadramawt) and the Horn of Afri
F_4_18 — Roman Britain and Beyond: Provincial Connectivity
Roman Britain (43–410 CE) — the province of Britannia — represents one of the most thoroughly documented examples of how Rome's imperial system connected a peripheral, previously fragmented region to continent-wide econo
F_4_06 — Pre-Indo-European Substrate Cultures of Europe
This document examines Pre-Indo-European Substrate Cultures of Europe, a topic within the Lost Connections research area. Key areas of investigation include Europe Before the Steppe Migrations, The Indo-European Expansio
F_4_07 — Sundaland and the Eden East Hypothesis
Sundaland — the vast continental shelf of Southeast Asia that was exposed during Pleistocene low sea levels — represents one of the most significant lost landscapes in human prehistory. At the Last Glacial Maximum (~26,0

Doggerland is the name given to the now-submerged landmass that once connected Britain to continental Europe across what is now the southern North Sea. During the Last Glacial Maximum (~26,500–19,000 years ago), when sea
F_4_04 — Post-Catastrophe Knowledge Preservation
If advanced civilization existed before the Younger Dryas impact (~12,800 years ago), how could its knowledge survive total civilizational collapse? This is not an idle question — it is the central engineering problem of
