Abiogenesis (for
the Origin of Life)
by Self-Organization

by Loren Haarsma, Ph.D. and Terry Gray, Ph.D.

      Is it possible that simple organic molecules could self-organize into a living, reproducing organism?  Given our current scientific understanding, it is far too premature to definitely answer either yes or no.
      There are many hypotheses for how first life might self-assemble on the early earth.  All of these hypotheses are still speculative.  The most widely accepted hypothesis is a multistep process something like this:  First, in the right environment (hypotheses include underwater thermal vents, shallow surface ponds, sandy beaches, volcanic craters, clay deposits, and weathered feldspar), simple organic molecules concentrated and self-assembled into strings of nucleic and amino acids (RNA and proteins).  Second, when enough of these molecules were concentrated together, they formed an interacting auto-catalytic system that jointly catalyzed their mutual reproduction.  Third, these RNA-and-protein catalytic systems evolved, with RNA and eventually DNA taking on the role of information storage, which we see in all living cells today.
