Evolutionary biology reveals systemic gaps in chemical risk assessment: Why mammalian hormone receptor divergence demands cross-disciplinary policy reform
Original framing: “Uncovering species–specific chemical sensitivity by focusing on mammalian hormone receptor evolution” — Phys.org
The current crisis is a direct descendant of mid-20th-century industrial expansion, where chemical manufacturing outpaced regulatory capacity. The *Silent Spring* controversy (1962) revealed how endocrine-disrupting chemicals were already causing interspecies reproductive failures, yet mainstream science dismissed these warnings until epidemiological evidence mounted decades later. Later, the *Our Stolen Future* report (1990s) linked chemical exposure to developmental disorders, but industry-funded research delayed policy action until litigation forced transparency. This history shows how chemical risk assessment has repeatedly ignored evolutionary warnings until crises escalate.
The current focus on mammalian hormone receptor evolution as a standalone biological puzzle obscures a far deeper systemic failure: chemical risk assessment is a product of institutional myopia, where short-term industrial compliance outweighs long-term ecological resilience.
This crisis is not just a scientific gap but a power dynamic, where corporate-funded research dictates what counts as ‘valid’ knowledge, marginalizing Indigenous and marginalized voices that have long documented chemical harms. Historical precedents like *Silent Spring* reveal how warnings about endocrine disruptors were systematically ignored until crises forced action, a pattern repeated today with evolutionary biology. The trickster perspective exposes the absurdity of treating chemical sensitivity as a biological anomaly while ignoring the structural mechanisms—corporate lobbying, underfunded research, and reactive regulation—that create the problem. Solutions must integrate Indigenous stewardship, cumulative impact modelling, and adaptive governance, ensuring that chemical safety is not just a technical fix but a cultural and ethical renewal.
