Theories of abiogenesis.

• Polymerization of long organic molecules on clay?

• Concentration of organic molecules in cracks in rock?

  • Either results in “chemical evolution.”
    • Lot of random chemical reactions lead to formation of many types of molecule
    • The most stable resulting molecules last the longest and are able to react with other molecules to produce larger daughter molecules.
    • The most stable daughter molecules last the longest and are able to react to form longer molecules.
    • Eventually one of the daughter molecules was able to replicate itself.

• Panspermia: Life arrived here from interstellar space.

  • Doesn’t really solve the problem, just changes its location.
