Abstract
We propose the Circum-Pacific Migration along-Pacific-Ocean-Rim (MPOR) model, integrating the Tri-Wave Stratification Hypothesis for Americas peopling. Wave 0 (25,000 BP~): Hokkaido ancestors (Sojin) via Kelp Highway reach White Sands footprints and seed Population-Y in South America. Wave 1 (20,000~ BP): Hokkaido main force establishes stemmed projectile points and AUP lithics. Subsequent Wave 2 (13,000 BP~): Siberian ANA via mainly ice-free corridor dominates Clovis culture. Synthesizing Hokkaido Okushirataki=AUP (USA) lithic continuity, marine adaptation, and genetic basal layers, this model resolves chronological paradoxes better than Beringian single-origin.
1. Introduction
Conventional Beringian models fail to explain:
- White Sands footprints (22,000 BP) predating ice-free corridor
- South American Population-Y Australasian affinity absent in North America
- Okushirataki (Hokkaido) = AUP (USA) lithic identity
MPOR+Tri-Wave resolves via Hokkaido ancestors’ maritime primacy.
2. Materials and Methods
Chronology: Radiocarbon from WS, Monte Verde, Clovis.
Lithics: Okushirataki vs AUP morphometry.
Genetics: Population-Y Australasian signals.
Marine OS: Sojin (Jomon precursor) boat and marine diet (40,000 BP~).
3. Results: Tri-Wave Stratification

| 0 | 25,000 | Hokkaido Pioneer (Sojin) | Kelp Hwy Frontier | WS Footprints, Pop-Y Basal | Coastal Leap | N.A. Penetration, S.A. Seeding |

4. Discussion
4.1 Wave 0: Pioneer Seeding
White Sands (22,000 BP) requires pre-corridor coastal route. Hokkaido Okushirataki Stemmed point precursors match AUP, confirming cultural continuity. Population-Y Australasian basal layer preserved in South America via early seeding.
4.2 Wave 1: Main Force Establishment
Stemmed points (18,000 BP) represent Hokkaido marine-adapted toolkit transition to interior hunting, establishing AUP culture.
4.3 Wave subsequent 2: Late Dominance
Siberian ANA via ice-free corridor overlays prior waves, explaining Clovis dominance and North American genetic homogenization.
5. Marine OS from Hokkaido
Hokkaido Jomon precursors develop island-hopping (Tsushima (40,000 BP) →Izu→Tsugaru Straits), uniquely enabling Kelp Highway. No equivalent in Siberian interior cultures.
6. Conclusion
MPOR+Tri-Wave uniquely integrates:
- Chronology: WS(22kya) → AUP(18kya) → Clovis(13kya)
- Lithics: Okushirataki=AUP identity
- Genetics: Pop-Y basal resolution
- Adaptation: Hokkaido marine OS supremacy
Testable Predictions:
- Hokkaido late Paleolithic DNA will cluster with Pop-Y basal
- Additional AUP-Okushirataki sites in Kurils
RSoJS model redefines Americas peopling as Circum-Pacific maritime innovation led by Hokkaido ancestors.
