West Polynesia (2,637 – 910 BCE): Proto-Settlement Horizons — Lapita Approaches and First Colonizations (Tonga–Samoa)

Geographic & Environmental Context

West Polynesia includes Hawaiʻi Island (the Big Island); Tonga (Tongatapu, Haʻapai, Vavaʻu); Samoa (Savaiʻi, Upolu, Tutuila/Manuʻa); Tuvalu and Tokelau (low atolls); the Cook Islands (Rarotonga, Aitutaki, Mangaia, etc.); Society Islands (Raiatea–Tahiti–Moʻorea–Bora Bora); and the Marquesas (Nuku Hiva, Hiva Oa).

• Anchors (settlement focus): Tongatapu–Haʻapai–Vavaʻu (Tonga), Savaiʻi–Upolu (Samoa); Society Islands–Marquesas–Cooks–Hawaiʻi Island remain unsettled; Tuvalu–Tokelau likely unsettled or only intermittently visited at the end of this span.

Climate & Environmental Shifts

• Holocene stability with episodic droughts; lagoons and leeward plains productive; reliable trade winds support long-range sailing.

Subsistence & Settlement

• Lapita voyagers (c. 900–800 BCE) colonize Tonga and Samoa: establish coastal hamlets on leeward flats and bay heads.

• Horticulture: taro, yam, banana, breadfruit; arboriculture (pandanus, coconut) planted; managed fallows.

Technology & Material Culture

• Lapita dentate-stamped ceramics, obsidian and high-quality cherts, one- and double-hulled canoes (waʻa), shell adzes, drilled pearlshell fishhooks, barkcloth (tapa).

Movement & Interaction Corridors

• Backbone route: Fiji–Tonga–Samoa; exploratory probes reach Cooks and Societies late in the epoch (no firm permanent settlement); Marquesas and Hawaiʻi Island remain beyond routine circuits.

Cultural & Symbolic Expressions

• Lapita ancestral iconography on pottery; early marae/ahu-like ritual precincts on beach ridges inferred from alignments.

Environmental Adaptation & Resilience

• Transported landscapes: portable cultigens, commensals (dogs, pigs, chickens), and agroforestry mosaics engineered for resilience; shoreline hamlets adopt storm-avoidance siting.

Transition

By ~910 BCE, Tonga and Samoa are settled Lapita frontiers; farther east and north (Cooks, Societies, Marquesas, Hawaiʻi Island), the ecological stage remains pristine, awaiting later pulses.
