Stuart Kauffman

Who is Stuart Kauffman?

Stuart Alan Kauffman is an American theoretical biologist and complex systems researcher who studies the origin of life on Earth.

In 1971, Kauffman proposed the self-organized emergence of collectively autocatalytic sets of polymers, specifically peptides, for the origin of molecular reproduction. Reproducing peptide, DNA, and RNA collectively autocatalytic sets have now been made experimentally. He is best known for arguing that the complexity of biological systems and organisms might result as much from self-organization and far-from-equilibrium dynamics as from Darwinian natural selection, as well as for applying models of Boolean networks to simplified genetic circuits. His hypotheses stating that cell types are attractors of such networks, and that genetic regulatory networks are "critical", have found experimental support.
