Evolutionary FDX1-LIAS Reconstruction
Ancient copper chemistry from deep-sea vents may have shaped the cell death machinery we carry today.
Cuproptosis is a recently discovered way that cells can die — triggered when too much copper builds up inside and causes certain proteins to clump together catastrophically. The proteins involved, including ones called FDX1 and LIAS, are ancient and fundamental to how cells generate energy. Meanwhile, hydrothermal vents on the ocean floor create rich, chemistry-intense environments where copper and sulfur minerals have been interacting for billions of years — long before life as we know it existed. This hypothesis proposes a connection: that the molecular machinery behind copper-induced cell death may have evolutionary roots in the geochemistry of early Earth's hydrothermal vents, where primitive life first encountered and had to manage copper. The idea is that life didn't just adapt to copper — it was shaped by it from the very beginning. If true, this would reframe cuproptosis not as a quirk of modern biology, but as an ancient, geochemically-forged survival mechanism.

Why This Matters
WARNING: The core mechanism of this hypothesis was not provided, so this impact statement is speculative and should not be treated as scientifically grounded. If confirmed, such a hypothesis could inform new cancer therapies that exploit copper-dependent cell death pathways, and might guide the search for life in extreme environments elsewhere in the universe. However, without a defined mechanism or evidence base, this hypothesis is not yet testable in a meaningful way — the priority should be developing the actual mechanistic claim before evaluating real-world impact.
