Inland big-game hunters cannot just drop their mega-spears and instantly “evolve” into master mariners to settle the Americas. It’s an evolutionary impossibility! The true pioneers? The 38k-year-old Izu Sojin with their advanced “Archipelago OS.”
🧠 Paradigm Shift: The Evolutionary Impossibility of the Western Migration Model “The conventional ‘Siberian-centric’ paradigm is untenable. The population in question represented an inland terrestrial lineage, entirely distinct from maritime cultures. The hypothesis that inland big-game hunters could abruptly abandon their specialized lithic weaponry to adopt an advanced coastal lifestyle is evolutionarily implausible. Rather, the primary candidates for this early migration are the Izu Sojin lineage of 38,000 BP, who carried the crucial ‘Archipelago OS’ required for open-ocean navigation.”
Let’s look at the actual technological compatibility.
There is a prevailing misconception in Western academia that because the “Coastal Route” to the Americas is gaining traction, early modern humans like Tianyuan Man must have been coastal navigators who directly contributed to the southern Beringian maritime migration.
However, paleogeographic reconstructions from 40,000 to 25,000 years ago completely refute this. During this period, sea levels were tens to over 100 meters lower than today. What we now call the Bohai Sea and the Yellow Sea did not exist; they formed the vast, exposed Northeast Asian Plain. Consequently, the Tianyuan Cave site near Beijing was not a coastal area, but located deep within the inland hilly and mountainous terrain. Tianyuan Man was an inland population, though genetically similar to the maritime groups that later utilized the northern coastal highways.
True maritime adaptation developed further east and north along the chain of islands—including Hokkaido, the Kuril Islands, relying on island-hopping where the next island was within line of sight—stretching toward the southern coast of Beringia. This Northern Pacific Kelp Highway Route of human dispersal involved seafaring starting, driven by populations expanding northward from the Southeast Asia and ocean crossing to Northern Kyusyu 40,000 years ago, eventually leading to a convergence of eastern and western routes at the Aomori Mutsu Plain. After the Launch Pad of Aomori/Hokkaido PAHK, they had navigated a harsh northern sea drifting with ice floes and migrated into Amazon and Patagonia. Therefore, conflating inland populations like Tianyuan Man with the specialized maritime innovators of the Paleo-Asian coastal route misinterprets both the Asian paleo-environment and the true history of human dispersal.

Executive Summary
Global academic discourse regarding the “First Americans” remains bottlenecked by a Eurocentric, Siberian-centric paradigm that overemphasizes the inland Mammoth Hunter lineage (Ancient North Eurasian / ANA) and the Clovis-First model. Furthermore, Western understanding of Japan’s deep past rarely looks beyond the Jomon period (approx. 16,500 years ago).
This report presents a disruptive, multi-wave migration framework proving that the true pioneers of the New World were maritime populations originating from the Japanese Paleolithic—the Sodai (祖代) / Sojin (祖人) era—who utilized the Kelp Highway via a unique Migration along Pacific Ocean Rim (MPOR).
1. The Three-Wave Stratified Migration Framework
The initial peopling of the Americas cannot be attributed to a single, monolithic inland migration. Archaeological and technological typologies dictate a clear three-stage stratification:
[Wave 0: Zero Wave] ➡ South America Deep Stratum (Population-Y/Coastal People as like Hokkaido Sojin) / Primitive Lithic Typology A
[Wave 1: First Wave] ➡ North American Coastal Pioneers (OAM/Hokkaido Sojin) / Advanced Lithic Typology B
The inland Mammoth Hunters, long celebrated by Western academia as the “First Americans,” were actually a later, subsequent wave. They did not discover an empty continent; they arrived to find a land already settled by coastal predecessors.
2. The Izu-Sodai Mariners & The PAHK Gateway
The technological blueprint for New World maritime migration was perfected 38,000 years ago in the Izu Archipelago of Japan.
The World’s Oldest Organized Navigation: Ancient Sojin navigated to extract obsidian from Kozushima Island. This was not accidental drifting; it was a highly organized, seasonal maritime operation requiring calculation of island visibility over a 20-kilometer open-water gap, though they had already crossed Tsushima Strait and migrated in western Japanese archipelago.
The PAHK Gateway (Paleo-Aomori-Hokkaido-Kurile): These advanced mariners did not originate from Sakhalin (PSHK). Instead, they migrated northward from the highly developed Mutsu Plains of Aomori, merging into Eastern Hokkaido. From this eastern launchpad, they rapidly accelerated along the Kelp Highway via the Kurile Islands to reach the American Pacific coast, Beringian South Seashore, as Original Advanced Mariners (OAM).
3. Resolving the Genetic Mystery: Population-Y and the MPOR Theory
Harvard Medical School’s groundbreaking discovery of an Australasian genetic signal (Population-Y / Onge / Aboriginal Australian affinity類縁性) in the deep indigenous strata of South America (such as Amazonian and Patagonian tribes) has left mainstream scholars baffled. A Siberian route cannot explain this Amazonian-Australasian link and it was unlikely for Tianyuan man to adapt for the maritime life in harsh North Pacific seashore.
The Maritime Pacific Rim Origin Route (MPOR) flawlessly resolves this enigma:
The Sundaland Outflow: During the Last Glacial Period, ancestral populations related to the Andamanese (Onge) and Australasians moved northward along the now-submerged continental shelves had migrated along coast to north and dispersed clockwise along coast of the Akebono Sea (曙海) (comprising the modern Yellow Sea, Bohai Sea, and East China Sea) to Northern Kyusyu.
The Archipelago Crucible: These populations converged firstly in the Japanese Archipelago, had become the indigenous Sojin lineages.
The Kelp Highway Launch: Carrying this distinct genetic signature, these coastal adapters far from the frozen Siberian interior entirely, navigating the North Pacific rim directly into the Americas.
Conclusion: A Call for Global Paradigm Shift
The Jomon culture did not emerge from a vacuum; it was built upon the 40,000-year-old technological and maritime foundation of the Sodai Era changing the terminology to Jomon after the appearance of pottery.
By redefining the “First Americans” through the lens of the MPOR Theory, we bridge the gap between Harvard’s genomic data and the physical reality of ancient maritime technology. It is time for global academia to recognize the Japanese Archipelago as the primary engine “Launching Pad” of early human expansion to the American continents.
