Re: [biopoet] evolution: simple to complex
Re: [biopoet] evolution: simple to complexYou should check out a paper David Hays and I wrote some years ago:
A Note on Why Natural Selection Leads to Complexity, Journal of Social and Biological Structures, Vol. 13, pp. 33-40, 1990.
While science has accepted biological evolution through natural selection, there is no generally agreed explanation for why evolution leads to ever more complex organisms. Evolution yields organismic complexity because the universe is, in its very fabric, inherently complex, as suggested by Ilya Prigogine's work on dissipative structures. Because the universe is complex, increments in organismic complexity yield survival benefits: (1) more efficient extraction of energy and matter, (2) more flexible response to vicissitudes, (3) more effective search. J.J. Gibson's ecological psychology provides a clue to the advantages of sophisticated information processing while the lore of computational theory suggests that a complex computer is needed efficiently to perform complex computations (i.e. sophisticated information processing).

Not being an expert on evolutionary theory, I have come to wonder how
theorists address the counter-gradient movement of evolution from simple
to complex, rather than the opposite direction. As I understand it, in
physics, unless a system has some kind of energy input(s), it will
entropically move towards simplicity, stability, and minimal energy
states to sustain it. Evolution, it seems obvious to me, is moving in
exactly the opposite direction: towards more complexity in living
systems, and more complexity in sustaining those living systems, both
individual and environmental.
Please explain. Thanx.
