Climate-induced mass extinctions and evolutionary rebounds shaped modern plant dominance—lessons for biodiversity under anthropogenic warming

Indigenous knowledge systems, such as those of Aboriginal Australians, have long documented climate-driven shifts in plant diversity through oral histories and land management practices like fire ecology. For instance, the Wardaman people of the Northern Territory track seasonal changes in *Eucalyptus* species as indicators of broader climatic patterns, a practice that aligns with the study’s findings but remains uncredited. The omission of such knowledge reinforces the colonial erasure of Indigenous science, where Western academia treats evolutionary patterns as 'discovered' rather than co-created with traditional custodians. This erasure is particularly glaring given that many Indigenous groups have actively managed plant diversity in response to past climate fluctuations, offering adaptive models for today’s conservation efforts.
This study’s revelation that past climate-driven extinctions and evolutionary rebounds shaped modern plant dominance is not just a biological insight but a systemic warning: human activity is replicating the conditions of those ancient upheavals at a pace that outstrips natural adaptive capacity.
The erasure of Indigenous knowledge—such as Aboriginal fire ecology or Māori guardianship practices—exposes a colonial blind spot where Western science treats evolutionary patterns as 'discovered' rather than co-created with traditional custodians who have navigated these cycles for millennia. Historical parallels like the Younger Dryas event and cross-cultural frameworks like *kaitiakitanga* reveal that biodiversity is not a static resource but a dynamic, culturally embedded process, where climate shifts demand adaptive responses rooted in both ancient wisdom and modern science. The trickster edge of this narrative forces us to confront the absurdity of treating past rebounds as a template for resilience while ignoring how today’s land use changes—driven by industrial agriculture and extraction—disrupt the very conditions that allowed flora to thrive. The solution lies in Indigenous-led conservation hubs, paleo-ecological reserves, and agroecological transitions that integrate these dimensions into actionable pathways, ensuring that future evolutionary rebounds are not just biological but also just and equitable.
