I try to avoid the content Jack Hudson’s blog. He doesn’t write anything of value and he hasn’t any credentials in the areas that seem to be slightly interesting to him (namely biology), but I often poke over there to see if I can find any interesting bloggers in his comments. Unfortunately, this involves me skimming his posts. (After all, if he writes about a topic that doesn’t interest me, I may not be interested in whoever might comment on it.) And once in awhile, I fully read his shorter rants. Take a look at one his his recent examples:
Often when I argue that cells are infused with information driven molecular machinery and that this observation constitutes the basis for a readily falsifiable theory on why the cell is the product of the effort of a mind, opponents will accuse me of over-extending the use of the word ‘machine’. That is why I appreciate animations like the one below – it clearly depicts a molecular motor, that has been an integral part of cells since the beginning of life. It is clearly a mechanism composed of multiple integrated and highly interdependent parts that both convert energy into work, and provide the fuel on which the rest of the cell subsists.
The ATP synthase is definitely an information driven molecular machine, and the best explanation of its existence is that it was designed by a mind.
I can be brief here: biology is all about shape. Again and again, anyone who has studied the subject will quickly recognize that the only way anything gets done is through the interaction of molecules of the correct shape. The only exception is when we’re talking about ion gradients or something sufficiently similar where the cause of action is an electrochemical gradient (or, again, something sufficiently similar). And even then, shape is often still relevant in moving stuff from one place to another.
When it comes to ATP synthase, the basic idea is that a phosphate molecule binds to an ADP molecule and causes a conformational change. This isn’t information (which, incidentally, is a concept Jack has never been willing to define in scientifically coherent terms). It’s a change caused by certain molecules of a certain shape with certain properties, coming together to form a new shape with new properties. And if we back the train up a little bit, we’ll see that that is the case for the previous molecules, and the previous molecules to those, and the previous…and so on until we aren’t talking about much more than very basic chemical bonds.
