  Stuart Kauffman - Wikipedia, the free encyclopedia
Stuart Alan Kauffman (born September 28, 1939), originally trained as a physician, is a theoretical biologist and complex systems researcher, who studies the origin of life.
Kauffman is presently a professor at the University of Calgary with a joint appointment between biological sciences and physics and astronomy.
Kauffman rose to prominence through his association with the Santa Fe Institute (a non-profit research institute dedicated to the study of complex systems, where he was one of the faculty in residence from 1986 to 1997) and through his work on models in various areas of biology.

 At home in the universe by Stuart Kauffman
Kauffman proceeds to suggest that increasing the concentration of the building blocks can get over of the problem of difference in energy, but of course this actually gets over the problem of entropy (which he ignored before), and does not affect the energy difference.
Kauffman is so keen to offer insights from his idealised models, that on page 107 he actually suggesst that a cell type corresponds to a state cycle with about 317 states of cell activity, and that the cell cycle (of duplication) corresponds to going through a state cycle.
Kauffman continues to suggest that if mix all the proteins in the world (his estimation 10**12) with all the molecules (his estimation 10**7), and calculate that as a result "A vast explosion of diversity would carom off the perplexed walls of Noah's groaning vessel" (p.

 Life - Wikipedia, the free encyclopedia
Variations of this definition include Stuart Kauffman's definition of life as an autonomous agent or a multi-agent system capable of reproducing itself or themselves, and of completing at least one thermodynamic work cycle.
A useful characteristic upon which to base a definition of life is that of descent with modification: the ability of a life form to produce offspring that are like its parent or parents, but with the possibility of some variation due to chance.

 Stuart Kauffman on The Paula Gordon Show
Kauffmanâs work and that of his colleagues in a range of disciplines from chemistry to economics further convince him that our world is profoundly unpredictable: we cannot know the outcome of our actions.
Dr Kauffman explores how all life is ãfunctionally coupledä in ãDarwinâs tangled bank.ä He weaves together the two strands of science which are the ãnarrativeä and the ãfunctional,ä looking for the ãlawfulnessä of what is unfolding.
Kauffman again reminds us that the Second Law of Thermodynamics explicitly holds at equilibrium and, as he described in detail in Segment One, the universe is in a vastly non-equilibrium state.

 At Home in the Universe. (Stuart Kauffman).
Kauffman's anti-DNA view holds for the origin of life, but in the ontogeny of multicellular organisms networks of genes are needed to enable cell differentiation.
Kauffman mentions inhibitors briefly in The Origins of Order[2], and concludes that they do not prevent autocatalytic closure, but inhibition is not a basic component of his model.
Kauffman's universe is fit for life because the probability of an arbitrary protein to catalyze another chemical reaction is high enough to guarantee autocatalysis.

Kauffman's project therefore is to use non-linear dynamics and computer simulations to massage our intuitions, make the search for laws of self-organization seem plausible, and ultimately facilitate the discovery of such laws.
Kauffman never clarifies what he means by complexity and order, or how these concepts apply in one case but not another.
Kauffman will write, "it is not implausible that life emerged as a phase transition to collective autocatalysis once a chemical minestrone, held in a localized region able to sustain adequately high concentrations, became thick enough with molecular diversity" (p.

Kauffman’s is the first comprehensive effort to apply complexity to the theory of evolution by placing evolution within a larger biophysical framework of potential universal laws.
Kauffman identifies two major limitations to selection, what he terms “complexity catastrophes.” In one scenario, as the complexity of the species increases, the fitness landscape it is operating in deforms to lower the overall possible fitness level.

Stuart Kauffman is a theoretical biologist who studies the origin of life and the origins of molecular organization.
STUART A. KAUFFMAN, a theoretical biologist, is emeritus professor of biochemistry at the University of Pennsylvania, a MacArthur Fellow and an external professor at the Santa Fe Institute.
(STUART KAUFFMAN): In his famous book, What is Life?, Erwin Schrödinger asks, "What is the source of the order in biology?" He arrives at the idea that it depends upon quantum mechanics and a microcode carried in some sort of aperiodic crystal—which turned out to be DNA and RNA—so he is brilliantly right.

Kauffman's previous book `At Home in the Universe' was aimed at the educated but non-specialist reader and extended those proposals for autocatalysis and self-organization in biological and chemical systems first described in Chapters 1 through 6 of his monumental `Origins of Order'.
Kauffman proposes that we live in a self-organised critical biosphere with a power-law distribution of small to large avalanches of speciation and extinction events.
Kauffman is chary of this because he wants a theory which gives a universe as complex as ours roughly poised between expansion and contraction.

Kauffman's biological autonomous agents perform their work cycles by consuming food (instead of heat) and in the process do work in the environment (work being the constrained release of energy).
Kauffman believes a work cycle is necessary for an autonomous agent, though from the flexible way he restates his 'definition', he might not consider it sufficient (leaving aside for a moment, the requirement to reproduce itself).

Kauffman replied that design theorists have not made their case to biologists, and don't deserve equal time in schools, because the fact of evolution appears to be incontrovertible.
Stuart Kauffman concluded with a brief discussion of Maxwell's Demon, a hypothetical construct that could appear to violate the laws of thermodynamics by, say, allowing only atoms of a certain speed to go though a hole connecting separate containers, thus changing the state into one of disequilibrium.

Stuart Kauffman followed Deamer with another presentation looking at the big picture of the evolution of life here on earth and in the universe at large.
Thus Kauffman postulates a possible 4th Law of Thermodynamics whose fundamental premise is that the biosphere is always seeking to expand its “adjacent possible.” In other words, the biosphere is rife with creative emergence, and it cannot be “pre-configured” as traditional science assumes.
Throughout his presentation Kauffman focused on his term “autonomous agent,” by which he means a system that is autocatalytic (self-reproducing) and does a thermodynamic work cycle.
