The Origin of Order When Darwin discovered evolution, he also
indirectly created the premises for a momentous paradigm shift. Over the
centuries, Science had always held that order can only be built by rational
agents (e.g., us) who apply a set of fundamental laws of engineering
(ultimately, Physics). Scientists such as Galileo and Newton simply refined that model by
using more and more sophisticated mathematics. Throughout the theoretical
developments of Physics, the fundamental idea remained that, in nature, order
needs to be somehow created by external forces. Darwin, instead, showed that
order can build itself spontaneously, without any help from a rational outside
agent. Evolution is such a process: it
is capable of building higher and higher degrees of order starting from almost
nothing. As far as Darwin was concerned, this paradigm only applied to Biology,
but his idea of spontaneous "emergence" of order can be applied to
any natural phenomenon. More than a century later,
Darwin caused a dramatic change in the
idea of Physics itself: are splitting the atom and observing distant galaxies
the right ways to explain the universe? or should we focus instead on the
evolutionary process that gradually built the universe the way it is now?
Should we study how things are modified when a force is applied (the vast
majority of what Physics does today) or should we deal with how things modify
themselves spontaneously? Can Physics ever explain how a tree grows, or how a
cloud moves, by bombarding particles with radiation? The macroscopic phenomena
that we observe are more likely to be explained by laws about systems than by
laws about particles. The subject of
Physics is still the origin of order, but the Darwinian perspective provided a
new approach. Furthermore, order is
directly related to information, and Darwins theory has to do with the creation of information (a new species is
a new pattern of information). From this new perspective, Physics may be as
much a study of information as it is a study of gravitation or electricity. And the creation of order is inevitably
related to the destruction of entropy (or the creation of negative entropy). In
the Darwinian view of things, entropy is therefore elevated to a higher rank
among physical quantities. Darwins laws (unlike the laws of nature claimed by physical sciences) cannot
be written down in the form of differential equations. Darwins laws can only
be stated in a narrative manner, and any attempt to formalize them resorts to
algorithms rather than to equations. Algorithms are fundamentally different
from equations in that they are discrete, rather than continuous, occur in
steps rather than instantaneously, and can refer to themselves. A Physics based
on algorithms would be inherently different from a Physics based on equations. Finally, Darwins paradigm is one that is rooted in the concept of organization and
that ultimately aims at explaining organization. Indirectly, Darwin helped us
understand the elementary fact that the concept of organization is deeply
rooted in the physical universe. Darwins treatise on the origin of species was indeed a treatise on the
origin of order. There lies its monumental importance. Back to the beginning of the chapter "Self-organization and the Science of Emergence" | Back to the index of all chapters |
