trochę świeżego powierza, pełny cytat…

Certainly the modern cellular machinery, the apparatus of DNA

replication and protein synthesis, has all the hallmarks of a highly

evolved, specially fashioned machine. We have seen how staggeringly

impressive it is as an accurate data storage device. At its own level of

ultra-miniaturization, it is of the same order of elaborateness and

complexity of design as the human eye is at a grosser level. All who

have given thought to the matter agree that an apparatus as complex as

the human eye could not possibly come into existence through

single-step selection. Unfortunately, the same seems to be true of at

least parts of the apparatus of cellular machinery whereby DNA replicates

itself, and this applies not just to the cells of advanced

creatures like ourselves and amoebas, but also to relatively more

primitive creatures like bacteria and blue-green algae.

So, cumulative selection can manufacture complexity while

single-step selection cannot. But cumulative selection cannot work

unless there is some minimal machinery of replication and replicator

power, and the only machinery of replication that we know seems too

complicated to have come into existence by means of anything less

than many generations of cumulative selection! Some people see this

as a fundamental flaw in the whole theory of the blind watchmaker.

They see it as the ultimate proof that there must originally have been a

designer, not a blind watchmaker but a far-sighted supernatural

watchmaker. Maybe, it is argued, the Creator does not control the

day-to-day succession of evolutionary events; maybe he did not frame

the tiger and the lamb, maybe he did not make a tree, but he did set up

the original machinery of replication and replicator power, the original

machinery of DNA and protein that made cumulative selection, and

hence all of evolution, possible.

This is a transparently feeble argument, indeed it is obviously selfdefeating.

Organized complexity is the thing that we are having

difficulty in explaining. Once we are allowed simply to postulate

organized complexity, if only the organized complexity of the DNA/

protein replicating engine, it is relatively easy to invoke it as a

generator of yet more organized complexity. That, indeed, is what

most of this book is about. But of course any God capable of intelligently

designing something as complex as the DNA/protein replicating

machine must have been at least as complex and organized as

that machine itself. Far more so if we suppose him additionally

capable of such advanced functions as listening to prayers and forgiving

sins. To explain the origin of the DNA/protein machine by

invoking a supernatural Designer is to explain precisely nothing, for it

leaves unexplained the origin of the Designer. You have to say something

like ‚God was always there’, and if you allow yourself that kind

of lazy way out, you might as well just say ‚DNA was always there’, or

‚Life was always there’, and be done with it.
