The Blind Watchmaker hypothesis says that natural selection, in combination with random mutation, has the kind of creative power needed to make complex plants and animals out of very much simpler predecessors. If Darwinian selection does not have the required creative power, then "evolution" in some general sense may still be true, but science does not know how creative evolution has occurred. The materialist belief that a blind watchmaker turned microbes into magpies, maple trees and musicians doesn't require any evidence because a blind watchmaker is a logical deduction from materialism. If a critic finds the current blind watchmaker inadequate to explain everything that's occurred in natural history, his only permissible move within science is to suggest a better blind watchmaker. That a competent blind watchmaker may not exist at all and that certain aspects of biotic reality may be better explained by a seeing watchmaker is not a logical possibility. Thus, most scientists don't investigate to determine IF life evolved, they only search for ways life DID evolve. Now, why should it be surprising to materialists that non-materialists remain skeptical of the current blind watchmaker hypothesis and feel that evidence for a seeing watchmaker may not be getting a fair hearing?
Richard Dawkins doesn't say that biology is the study of complicated things that give the appearance of having evolved. Instead he says, "biology is the study of complicated things that give the appearance of having been designed for a purpose." If nature looks this way to a materialist like Dawkins then what's wrong with a non-materialist having a suspicion that biological things that exhibit machine-like complexity look designed because they are designed? In particular those things for which there is no evidence they evolved solely through non-intelligent processes.
Here is an interesting quote that describes the machine-like nature of the cell:
"We have always underestimated cells. Undoubtedly we still do today. But at least we are no longer as na‹ve as we were when I was a graduate student in the 1960s. Then, most of us viewed cells as containing a giant set of second order reactions: molecules A and B were thought to diffuse freely, randomly colliding with each other to produce molecule AB - and likewise for many other molecules that interact with each other inside a cell. But, as it turn out, we can walk and we can talk because the chemistry that makes life possible is much more elaborate and sophisticated than anything we students had ever considered. Indeed, the entire cell can be viewed as a factory that contains an elaborate network of interlocking assembly lines, each of which is composed of a set of large protein machines." [Alberts, B. 1998. The Cell as a Collection of Protein Machines: Preparing the Next Generation of Molecular Biologists. Cell 92; 291-294.]
Physicist and science writer Paul Davies also has come to understand the essence of life at its molecular level. In his book The Fifth Miracle he says:
"Each cell is packed with tiny structures that might have come from an engineer's manual. Miniscule tweezers, scissors, pumps, motors, levers, valves, pipes, chains, and even vehicles abound. But of course the cell is more than just a bag of gadgets. The various components fit together to form a smoothly functioning whole, like an elaborate factory production line. The miracle of life is not that it is made of nanotools, but that these tiny diverse parts are integrated in a highly organized way."
Is the ultimate origin of the cell better explained as the product of advanced biomolecular engineering or is it better explained as the product of non-intelligent processes? Some scientists are logically inferring that life is carbon-based nanotechnology and are generating testable hypotheses from this perspective. One of them is Mike Gene. Here is an interesting observation from him:
"The specified complexity we find within the cell expresses itself in a dynamic three dimensional way and I would thus define it as machine-like complexity (MLC). With machine-like complexity, we are dealing with function that not only depends on arrangement (of parts), but also the conformation of those parts, their positioning, and timing. All of these are important such that you get coordinated movement of the parts as it is this coordinated movement that carries out the function....
Now as I see it, the inference to design from machine-like complexity (MLC) is a pretty darn reliable inference. I go through life inferring intelligence from MLC and don't live in a maze of confusion because of multiple mistakes in inferring intelligence from MLC, only to find the MLC arose from some non-intelligent mechanism. In the world I move through, intelligence is the default explanation for machine-like complexity, not merely because experience says so, but because MLC can be rationally viewed as the frozen trace of Mind. It's such a *natural*, free-flowing, and beautifully simple inference that I would need more than a possibility to attribute it to something other than intelligence. When I confront MLC, I don't naturally say, "Now *there's* evidence of a non-intelligent cause!" Perhaps if I had a history of being misled by this inference, I would take the mere possibility of MLC coming from non-intelligent mechanisms more seriously. Those who insist on attributing MLC to non-intelligence are free to do so a far as I am concerned. But if they expect me to make the same attribution, they will need more than a claim about how things might happen. They will need some good old-fashioned evidence to show that the particular example of MLC in question did indeed arise from a non-intelligent mechanism. I simply see no evidence that machine-like complexity-from-non-machine-like complexity is generated by non-teleological means, yet it is also quite clear that ID is a known cause for machine-like complexity."
