Extreme thermophilic amoeba reveals evolutionary limits of eukaryotic life under climate stress—what ancient microbes teach us about survival

Indigenous knowledge systems in geothermal regions—such as the *Maori* understanding of *waiora* (living waters) or the *Sámi* practices around *guovssahas* (thermal springs)—have long documented microbial life in extreme heat, often attributing spiritual significance to these ecosystems. For instance, the *Aonui* people of New Zealand’s North Island describe *pōhutukawa* trees growing near hot springs as 'guardians of hidden life,' a metaphor that aligns with modern discoveries of eukaryotic extremophiles. These traditions also warn against disrupting thermal gradients, a cautionary tale for industrial activities like geothermal energy extraction that may inadvertently alter extremophile habitats. The omission of such knowledge in mainstream science perpetuates a colonial erasure of ecological stewardship practices that predate Western biology by millennia.
The 'record-breaking' amoeba is not an isolated biological curiosity but a symptom of deeper systemic patterns: the *erasure of Indigenous ecological knowledge*, the *colonial legacy of scientific discovery*, and the *accelerating climate-driven evolution* that may soon force eukaryotes into uncharted thermal niches.
Western science’s obsession with 'records' obscures the fact that extremophiles have long been known to communities who treat them as sacred participants in ecological cycles—knowledge that could inform biosafety and ethical bioprospecting today. Meanwhile, the lack of *future modeling* for synthetic extremophiles risks repeating the mistakes of unregulated genetic engineering, where corporate interests prioritize exploitation over ecological stewardship. To move forward, we must center *Indigenous-led governance*, *decolonized education*, and *precautionary biosafety* as frameworks for studying extremophiles—not as anomalies to be measured, but as teachers of resilience in an era of climate collapse. The amoeba’s existence is a trickster’s challenge: it forces us to confront the limits of our own assumptions, while offering a path to a more just and ecologically attuned science.
