I thought you might have the intellectual ability and force of character to support it.</i><br /><br />Your first question was:<br /><br /><i>In what way is a final cause an explanation?</i> <br /><br />Final causes are future conditions, entities, or events regarded as the cause of the thing in question. Or, an event's final cause is the aim or purpose being served by it.<br /><br />http://en.wikipedia.org/wiki/Four_causes<br /><br />Thus to acknowledge a final cause as an explanation for the origin of the potassium channel is to acknowledge that the channel's role, purpose, function, etc., could have driven its creation process. Just as when a craftsman builds a piece of furniture, he is not doing it blindly. The furniture's function and purpose is driving his work in creating it. That explains why he uses a tool in a certain way, in a certain place, at a certain time as opposed to "Gee, that was lucky."<br /><br />Now my question for you: How do evolution's astronomically unlikely explanations help science?<br /><br /><i>What is the final cause of the potassium channel?</i><br /><br />It's incredible performance of allowing potassium ions pass through the membrane at the maximum speed that is physically attainable and yet with incredibly high selectivity, filtering out other types of ions.Cornelius Hunterhttps://www.blogger.com/profile/12283098537456505707noreply@blogger.comtag:blogger.com,1999:blog-3855268335402896473.post-84814360217514857822014-12-24T16:51:46.963-08:002014-12-24T16:51:46.963-08:00Wow... 0 to personal in 4 sentences.

A constantly changing 'charge contour' created by raising the energy level of electrons in each ion, then allowing it to fall at the right moment. <br /><br />What's not stated in the article is HOW these changes are induced by the structure. I can't tell if that's obvious to the authors or yet to be researched.Polistrahttps://www.blogger.com/profile/09594313902571823549noreply@blogger.comtag:blogger.com,1999:blog-3855268335402896473.post-77128122828315018182014-12-11T22:47:33.041-08:002014-12-11T22:47:33.041-08:00Oh yes, several different ions are important, and ...Oh yes, several different ions are important, and as for the channels, that is yet another story. There are entire books devoted simply to documenting all the different variations on the channels. And no, they are by no means restricted to eukaryotes. Regarding efficiency, etc, again, there is a large diversity with different selectivities, efficiency, etc. So no, not all known ion channels are similarly efficient. But there is no scientific explanation for how these channels could have evolved. In fact, there is no such explanation for far simpler proteins.Cornelius Hunterhttps://www.blogger.com/profile/12283098537456505707noreply@blogger.comtag:blogger.com,1999:blog-3855268335402896473.post-18247272578036803922014-12-11T21:57:31.430-08:002014-12-11T21:57:31.430-08:00Dr. Hunter, thanks for posting again.

I have responded to your post by googling a bit, but I am still unclear. It does seem clear that there are a number of different ions, not just potassium, that go through matching channels.<br /><br />Are these a phenomenon of eukaryotes, or does it exist in bacteria as well? <br /><br />Are all known ion channels similarly efficient? <br /><br />Is there any evidence that along one node of the "tree" potassium channels work one way, and on another node they work another way?bFasthttps://www.blogger.com/profile/13584931926133025618noreply@blogger.com
