Myrid, I find your hypothesis uncompelling.
Why? Well, we already have computer programs that use the same heuristics used by evolution. We have programs that use better heuristic searches than evolution - better by a long shot. Yet we don't call these systems intelligent.
The search heuristic of evolution is extremely basic. Genes change, and either survive, or don't. The mechanisms of course are more complicated (how do the gene's change - well, a number of ways. etc.), but that doesn't seem to be a measure of intelligence.
...
This is not intelligent behavior. Complex, yes, but not intelligent (by my intuitive definition/understanding of the word). But it is already orders more complex than the simple system of evolution.
I think what Myriad brings up is an interesting topic. I've brought it up recently in other threads around here.
Roger, you explain that you think the system of evolution is simple. "The search heuristic... is extremely basic" - you said. "Complex, yes..." you say, but not intelligent.
I agree with you. BUT...
Let's back away and look at the big picture. First, let me say that it is a mere assumption that the "heuristics", namely random mutation and natural selection, are complete. Are you sure that our model is good enough? Is it complete enough so that what any of what you said makes any sense? Maybe there is a missing component that makes evolution have something other than a zombie mechanistic process. We just assume it doesn't. Best reason is occam's razor and no direct evidence, most will say.
Okay, well let's allow that the heuristics of random mutation and natural selection are sufficient for creation of new organisms for the sake of continuing what I was going to say.
Think of natural selection as being a huge interconnection of organisms with each other and organisms with the physical world. Even sunspots and cosmic radiation play into the selection landscape here. If you were to try to model natural selection you would have to identify innumerable objects with innumerable interconnections and variable weightings, etc etc. Now, compare this with a model of the human brain.
The number of objects in natural selection, consisting mostly of one-cell organisms, and secondarily of multi-cellular organisms, is many orders of magnitude greater. A similar comment can be made about the interconnections, because in the brain there are only billions of neurons and "only" 1,000 to 100,000 interconnections between one neuron and other neurons.
The brain, actually infinitesimally as complex as natural selection, has this thing "intelligence". Why can't this much more complex (an engineer might say infinitely more complex) thing called natural selection also have "intelligence"? Food for thought... My answer is it takes a lot more than myriad-complexity to produce this thing that emanates from "mind": intelligence, planning, intent, self-awareness, consciousness.
Roger, you have stated Nature is not intelligent and I agree, but the idea that something as complex as Nature (specifically natural selection) can cause to come into existence "intelligence", and have this intelligence run on less hardware (the little ol' human neural network) than the physical engine of natural selection , to me, is a compelling question.
I have yet to see someone here directly respond to this question I've presented multiple times here. You are invited. What about the natural selection mechanism being the author of intelligence, an intelligence contained in a 10^10 object network (brain), yet the natural selection mechanism cannot (does not?) support intelligence within itself, even though it is many many orders of magnitude more complex than the brain?
