2. Deep Sea Vent Hypothesis
The Deep Sea Vent Hypothesis posits that life originated near hydrothermal vents on the ocean floor, where mineral-rich, heated waters provide the energy and raw materials necessary for complex molecules to form. (ucl.ac.uk) These vents create unique environments with steep temperature and chemical gradients, facilitating the synthesis of organic compounds. (scientificamerican.com) The presence of natural micro-compartments within the vent structures may have further concentrated these molecules, promoting the emergence of early life forms.
