Project Overview
At SIG Science, we are actively developing a new synthesis of Austronesian expansion models — integrating genetics, linguistics, and archaeology into a more dynamic, multidirectional framework.
The traditional Out-of-Taiwan (OOT) hypothesis framed the expansion as a single, Neolithic-driven migration.
Recent advances in genetic studies, computational linguistics, and maritime archaeology reveal a much more complex story.
Working Hypothesis:
The Austronesian expansion was not a single dispersal, but a long, layered maritime interaction process involving early Indigenous populations, multiple waves of cultural transmission, and dynamic coastal networks.
Why We Are Sharing This Early
This project is open for collaboration.
If you are a researcher in genetics, linguistics, archaeology, underwater survey, ancient DNA analysis, or computational historical linguistics, we invite you to engage.
You can pick up this framework inside a Research Clinic session — or propose direct field or lab partnerships.
We believe cross-disciplinary synthesis is essential to reframe one of the most critical migration narratives of the global south.
Key Findings We Are Developing
| Area | Emerging Evidence |
|---|---|
| Genetics | Modern Austronesian-speaking populations show 20–40% Taiwanese ancestry, but 50%+ local Hoabinhian, Papuan, and Denisovan ancestry (Lipson et al., Larena et al.) |
| Linguistics | Taiwan remains diverse, but contact signatures (Austroasiatic, Papuan) and cases like Cham suggest layered dispersals and lateral transmission |
| Archaeology | Early maritime networks across Sundaland and Wallacea predate Taiwanese Neolithic expansion; submerged landscapes complicate full reconstruction |
What We Are Proposing
A Maritime Interaction Model of Austronesian dispersal:
| Phase | Description |
|---|---|
| Pre-4000 BP | Coastal trading networks across Sundaland, Wallacea, and South China Sea |
| 4000–3000 BP | Taiwan acts as cultural amplifier, not singular origin |
| 3000–1000 BP | Bidirectional flows: Cham migration west, Polynesian migration east, with heavy integration and feedback |
This model emphasizes integration, admixture, and resilience, not simple replacement.
Research Directions for Collaboration
We are especially seeking partners for:
- Ancient DNA sampling in Vietnam, Cambodia, Philippines, and Wallacea
- Submerged archaeology targeting lost coastal settlements
- Lateral transfer computational linguistics for Austronesian-Austroasiatic interaction zones
- Deep analysis of boat-building and material culture parallels across ISEA
We welcome serious collaborators ready to help formalize, refine, and publish this synthesis.
Why This Matters
Understanding the Austronesian expansion better is not just an academic exercise.
It reframes critical questions about:
- Indigenous maritime technologies
- Human adaptation to climate change (Holocene sea rise)
- Deep-time cultural resilience strategies
- Post-colonial reconstructions of Southeast Asian prehistory
Austronesian history is a story of survival, synthesis, and innovation.
We believe telling it better is an act of intellectual restoration.
How to Join the Research Clinic
If this work resonates with your expertise:
- Contact us via our Research Clinics page (menu link)
- Propose a co-authoring session for article finalization
- Suggest a data partnership if you are working in ancient DNA, archaeology, or comparative linguistics
We operate using modular, transparent, version-controlled writing processes.
Final Word
At SIG Science, we do not gate knowledge.
We build scaffolds — for faster collective discovery.
The Austronesian expansion is not one story. It is a living network.
Let’s rebuild its true map together.
