Bohm, I'd love to see how information is generated via natural selection and mutation, however I haven't found any literature which shows how this is possible.
Let me explain my understanding.
Let's say we don't believe in any Lamarkian system of aquired characteristics or morphogenetic fields...
This means that natural selection is differential reproduction, which is nothing more than a competition as to who can produce the most offspring and keep that going over time.
Natural selection acts as a sifting mechanism. It doesn't generate novelty, it acts with veto authority. It says yea or nay, nothing more.
This leaves mutation as the only novelty generating mechanism.
This is suggested to have no teleological end, no purpose and no purposer behind its operation.
What is the rate of mutation?
What mutagens are available?
No matter this we can by way of illustration use a sentence like:
"The cat chased the rat."
This is an organism which, natural selection will act upon. The rules are that in order for this organism to be selected it must have an advantage in the differential reproductive realm as a result of the mutation aquired, or this mutation should at least be benign as regards differential reproduction. That is the sifting mechanism.
Now let's say by way of illustration that the for any sentence, to be viable, it must make semantic sense and gramattical sense, otherwise it is a dead, nonreproducing sentence.
Now let's "mutate" this sentence and see how much novelty we can generate.
"The cat chased the bat"
"The bat chased the bat"
"The bat chased the rat"
"The bat chased the hat"
"The cat chased the hat"
"The rat chased the hat"
"The rat chases heat"
You can permute and mutate the sentence, but it must operate within certain bounds, and aquisition on new information is quite difficult.
Now ask yourself about mutation rates and see if current rates of mutation would lend themselves to the rates required to go from the 3,000 nucleotides for say virus x0174 (BTW with 5,386 nucleotides)
http://en.wikipedia.org/wiki/Phi_X_174
You can see over 3,000,000,000 nucleotides in the human genome, so the idea that mutation and natural selection acting as a sieve is simply insufficient to the task assigned to it.
You can't generate more information in a random process, and yet here we are, obviously more complex but without an adequate explanation for the insertion of all this additional information.
