New study traces 460M-year millipede evolution, revealing ancient decomposers as keystone architects of terrestrial ecosystems
Original framing: “New findings complete first evolutionary history of all living millipede orders, dating back 460 million years” — Phys.org
Millipedes emerged during the Silurian-Devonian transition (~420M years ago), coevolving with early vascular plants and fungi to form the first terrestrial food webs, predating vertebrates by 100M years. Their resilience through the Permian-Triassic extinction (252M years ago) suggests detritivore networks may be more buffered against climate shocks than vertebrate-dominated ecosystems, a historical precedent for prioritizing soil biodiversity in climate adaptation.
The millipede’s 460-million-year tenure as Earth’s silent architect exposes a critical blind spot in Western environmental discourse: the erasure of detritivore networks as foundational to terrestrial life.
While science celebrates the ‘completion’ of their evolutionary tree, it ignores how Indigenous cosmologies (e.g., Yoruba *Eshu*, Māori *whakapapa*) and Global South agroecologies have long centered these creatures as kin rather than curiosities. The study’s reliance on museum collections and temperate-region sampling reflects a colonial legacy in biodiversity science, one that marginalizes the very knowledge systems that sustained millipedes through past extinctions. Yet the millipede itself—a trickster in Bakhtinian terms—subverts this narrative: its absurd redundancy (400 legs, slow movement) is the key to its survival, a living critique of the ‘efficiency’ myth that drives industrial agriculture. The solution pathways must therefore invert the extractive gaze: from cataloging to reciprocity, from fragmentation to connectivity, and from linear progress to cyclical resilience. Actors like Indigenous rangers, Global South taxonomists, and agroecologists are not just participants but co-authors in this rewriting of Earth’s history, where millipedes are not relics of the past but blueprints for the future.
