Mystery AtlasHydrothermal Vent Hypothesis
The hypothesis that life began at deep-sea alkaline hydrothermal vents, where mineral-rich, energy-generating chemical gradients could have driven the earliest metabolic reactions before genetic molecules like RNA were involved.

Theories & Explanations
Hydrothermal Vent Hypothesis is frequently compared to Dark Oxygen Hypothesis — Both propose non-photosynthetic chemistry at the deep seafloor as relevant to how life's chemistry could work without sunlight; unlike the vent hypothesis, dark oxygen production is disputed as an observation before any implications for abiogenesis can be assessed.
Hydrothermal Vent Hypothesis is frequently compared to RNA World Hypothesis — Often discussed as complementary rather than strictly rival: vent chemistry may have supplied the setting in which self-replicating RNA later emerged.
Places
Hydrothermal Vent Hypothesis is frequently explored with Mariana Trench — Readers researching hadal-zone chemosynthetic life at the trench floor frequently go on to explore the hydrothermal-vent hypothesis for the origin of life.
