Slide: Can Probability be of an Analog for Intentionality? | | |
Prior
to Darwin, the overwhelmingly prevailing explanation for the origin and maintenance of life on earth boiled down to the existence of an intentional creator being. In other words, the explanation devolved into one of teleology Ð intentionality, purposefulness, a causal chain of events controlled by a creator. But
DarwinÕs theory of evolution introduced chance
variation in the form of genetic copy errors and mutations as being responsible for the maintenance of life on earth. And, because of the limitations of resources resulting from living organisms consume each other; chance further operates through the process of natural selection. Thus, chance is everywhere involved in driving biological evolution. Jacques
Monod, co-discoverer of the gene synthesis and regulation processes and Noble laureate is even more explicitÉ. | Is
probability really at the heart of the origin and evolution of life? Is
the theory of evolution really a probabilistic analog of the teleologically created, causal process that is life on earth? That
is, can the apparently intentional and deterministic creation of life on earth be adequately described by a theory
based on chance and articulated by probability? Organodynamics
says Yes to this proposition. | |
ÒWe
call these events [molecular genetics] accidental; we say that they are random occurrences. And since they constitute the
only possible source of modifications in the genetic
text, itself the sole repository of the organismÕs hereditary structures, it necessarily follows that chance
alone is at the
source of every innovation, of all
creation in the biosphere. Pure chance, absolutely free but blind, at the very root of the stupendous edifice of evolution: this central concept of modern biology is no longer one among other possible or even conceivable hypotheses. It is today the sole conceivable hypothesis, the only one that squares with observed and tested fact.Ó [Monod 1972] | I am not alone in this suspicion. Nobel
laureate Jacques
Monod, who co-discovered both the gene
expression and the gene
regulation mechanisms shortly after the discovery of DNA, expresses a belief in the
primacy of chance in the development
and evolution of life on earth thusly (see frame to the left): |
