Final answer:

Hydrothermal vents are theorized to be the birthplace of early life on Earth due to evidence like thriving communities discovered in 1977, the chemical origins hypothesis, and evidence from the Hadean and Archean Eons.


Explanation:

Hydrothermal vents deep in the ocean are hypothesized to be the birthplace of early life on Earth due to various lines of evidence:

  1. Discovery of thriving communities in 1977: Scientists found organisms around hydrothermal vents, surviving in extreme conditions devoid of sunlight and oxygen, relying on chemosynthesis.
  2. Chemical origins hypothesis: The unique environment of hydrothermal vents with hot chemical-rich waters may have facilitated the synthesis of organic molecules, sparking life.
  3. Hadean and Archean Eons evidence: Fossils, microbial mats, and organic signatures dating billions of years back support the idea of life originating near hydrothermal vents.
