SUMMARY:Chemical selection and the origin of life\, Chaos & Complex Sy
 stems Seminar\,  David Baum\, UW Department of Botany
DESCRIPTION:The underlying puzzle of the origin of life is\, How could
  something capable of evolving by selection arise spontaneously? The m
 ost compelling hypothesis is that autocatalytic metabolic networks aro
 se on mineral surfaces and could evolve adaptively by an analog of gro
 up selection. Such adsorbed\, life-like chemical complexes would be ex
 pected to yield cell-like entities as a means to solve the problem of 
 colonizing other mineral surfaces. This theoretical framework for expl
 aining the origin of life suggests a class of experiments\, which we a
 re now embarking upon: selecting for collective mutual catalysis on co
 mplex chemical mixtures associated with mineral surfaces.
