Polynesian Research Brief — September 18, 2026
One major peer-reviewed ANU Press volume appeared; these are its strongest contributions.
Editor's note: This week centres on a single peer-reviewed volume on the Mariana Islands. CHamoru history is Micronesian, not Polynesian; it appears here because it sharpens how we separate documentation from interpretation across Oceania.

People Everywhere: Anthropomorphs as the Dominant Motif in the Rock Art of Guam
Andrea Jalandoni et al. ·
Established archaeological evidence
Why it matters
Digital documentation of 12 Guam rock-art sites identified 105 high-confidence anthropomorphs; a strong model for documenting form, pigment, location and confidence before interpretation.
Caution / interpretation boundary
Connections to ancestral skull veneration or taotaomo’na are culturally informed interpretations, not deciphered meanings; gender assignments and some motif identifications remain uncertain.

Community-Based Archaeology on Guam
Joe Quinata and Anthony Alvarez ·
Indigenous scholarship
Why it matters
Argues elders, practitioners, oral histories and community priorities must partner in archaeological interpretation; a useful editorial standard for inherited-design claims.
Caution / interpretation boundary
Methodological and ethical framework, not evidence for a particular motif's historical meaning.

Reframing Population History and Origins in Remote Oceania: The Marianas Ancient DNA Project
Joanne Eakin ·
Established genetic evidence with interpretation
Why it matters
Ancient DNA indicates substantial maternal continuity between early inhabitants and modern CHamoru people while suggesting later population movement; helps avoid flattening CHamoru, Lapita and Polynesian histories.
Caution / interpretation boundary
The eastern Indonesian or "sea nomad" origin model remains a hypothesis; samples are limited, later-phase results preliminary, and maternal lineages do not describe total ancestry.

A Distinctive Ceramic Surface Treatment at Two Sites in Northern Guam
David DeFant and Boyd Dixon ·
Established archaeological evidence with competing interpretations
Why it matters
Rare punctate and shallow-impressed Latte-period pottery may track technical communities, residential affiliation or exchange without assuming fixed symbolic meanings.
Caution / interpretation boundary
Production locations unknown and samples small; functional roughening, group affiliation and exchange remain competing explanations.

Ancestral Sea Nomads and Achugao Incised Pottery
Boyd Dixon and Nina Peck ·
Established archaeological evidence with interpretation
Why it matters
Early Pre-Latte Saipan deposits include carinated bowls with incised, punctate and sometimes lime-filled decoration — useful comparative material for specialist production and communities of practice.
Caution / interpretation boundary
Proposals about women preserving meanings through ceramics, clothing, ornaments or ritual are explicitly speculative and need testing.
