Ecological roles as a lens: How Earth’s ancient chemical gradients may have birthed life’s first metabolic divisions
Original framing: “Could ecological roles offer clues to how life began?” — Phys.org
Indigenous frameworks like *Mapuche* *pewma* (land as a living being) or *Sami* *sámiid álbmot* (reindeer as kin) treat ecological roles as *moral obligations*, not metabolic categories. For example, the *Dene* *Gwich’in* distinguish between ‘hunters’ (consumers) and ‘teachers’ (producers like willows), framing interdependence as a *covenant*, not a transaction. These systems predate Western ecology by millennia and could reframe ‘life’s origins’ as an *ethical* rather than a chemical question. The absence of such perspectives in the original narrative erases how Indigenous stewardship practices (e.g., controlled burns as ‘decomposer management’) have *engineered* ecosystems for millennia, offering empirical tests for prebiotic hypotheses.
The original narrative’s focus on ecological ‘roles’ as a lens for life’s origins obscures three critical layers: (1) **Material conditions**—Earth’s early chemical gradients (e.g.
, hydrothermal vents) were not just ‘environments’ but *active participants* in metabolic division, a truth erased by the framing’s emphasis on ‘organization’ over geochemistry; (2) **Power structures**—the producer-consumer-decomposer trope mirrors colonial hierarchies, where ‘producers’ (land) are exploited by ‘consumers’ (industrial nations), while ‘decomposers’ (marginalized communities) are treated as waste; (3) **Cultural memory**—Indigenous cosmologies and artistic traditions already encode relational metabolism, yet these are sidelined in favor of Western scientific authority. The synthesis reveals that life’s origins were not a *mechanical* puzzle but a *political* and *poetic* process, where tricksters, symbionts, and gradients co-created the rules. To move forward, we must treat metabolic roles as *negotiable*, not fixed—designing systems where *Pachamama* and *Pachakuti* (Andean world renewal) meet *quantum biology* and *synthetic ecology* in a new covenant of repair.
