  • Unresolved Questions About the Origins of Life

    • There is substantial understanding of how inorganic molecules can give rise to somewhat simple building blocks of life in the process known as abiogenesis.
    • There are a few problems consistently seen in most scenarios of abiogenesis.
    • One further problem confronting many abiogenesis models is homochirality.
    • It should be clear the term extraterrestial in these abiogensis models are not referring to little green men, but rather complex organic molecules, of which the abiogenesis occurred in the more favourable conditions for such reactions in space.
    • While the idea of extraterrestrial abiogenesis once seemed far-fetched, the presence of organic molecules on meteorites (and recently in stars themselves) adds credence to this exciting possibility .
  • Pasteur and Spontaneous Generation

    • However, the principles of the very different matter of the original abiogenesis on this planet — of living from nonliving material — are still under investigation.
