Hydrothermal Vents and Life's Origin
- Hydrothermal vents, discovered in the 1970s, are deep-ocean chimneys spewing minerals and hot water.
- These vents support diverse life forms, leading some scientists to theorize that life originated there.
Water's Role in Life's Origins
- Two main theories about life's origins involve water: hydrothermal vents and tide pools.
- Oceans offer a nurturing environment with less gravity and stable temperatures, favoring the emergence of life.
Chemosynthesis vs. Photosynthesis
- Life around hydrothermal vents thrives through chemosynthesis, using chemicals for energy instead of sunlight.
- Tide pools offer wetting and drying cycles, which are believed to be crucial for bonding molecules and forming complex life.
