LETTER OF DR SPETNER MY REPLY Spetner 31 Aug 2000 7 Oct 2000 24 Jan 2001 Dear Gert, Dear Gert, Dear Lee, I read your detailed review of my book Not You formatted your reply to me very well - By Chance! I commend you on the effort Thank You! I am very honoured to be putting your comments side by side with you put into it and the knowledge you compared favourably to Richard Dawkins! mine in two columns. I don't think I can exhibited. I think you are a better defender And I keep trying to improve my prose. extend that to 3 columns to include my of evolution than Richard Dawkins. His But most off all I appreciate it very much second response to you, so I have adopted prose may be better than yours (of course, that you took the trouble to write such a the format below to show the entire English is his native tongue), but your detailed reply. I posted it without hesitation dialogue from the beginning, starting with substance is superior. I do, however, think on my site, because it is not hostile at all, my original response. I trust you would see your review deserves a critical answer. Let despite the fact that you and I entertain fit to post this on your website to replace me offer you my detailed critique of the fairly opposite opinions. the dialogue you now have. I'm sure you review, point by point. will be able to choose a suitable format. I'll tell you why I'm using Evolution A and B instead of macro & micro evolution. I'm using Evolution A precisely because I want Before I enter into the critique itself, let me to distinguish it from macroevolution. I am establish an important and necessary using it precisely to avoid the confusion guideline. The word evolution is generally demonstrated in some of your remarks used in at least two different senses, and below. Thus, your equations, above, do not the distinction is important in discussing I don't understand why you use Evolution represent what I intended in the meaning of your review, and in almost any discussion A, Evolution B, because in your book Evolution A. By Evolution A, I mean what of evolution. One meaning of evolution is starting on page 67 you use the well- I had earlier called "the grand sweep of the descent of all life from a putative single known concepts 'micro-' and 'macro'- evolution," the evolution of all life from primitive source. I shall denote the word evolution. For this discussion: some simple beginning. It is the same as used in this sense as Evolution A. On the common descent, but somehow the term other hand, the word is also used to denote Evolution A = macro evolution = common descent doesn't capture the drama any kind of change of a population. The Common Descent of the grand sweep of evolution. Maybe change can sometimes occur in response to Evolution B = micro evolution = changes Evolution A is too insipid a term, but I environmental pressure (natural selection), in populations wanted something shorter than "the grand and sometimes it can just be random sweep of evolution." I thought I would (genetic drift). I shall denote the word used gain some clarity with this terminology. in this sense as Evolution B. Evolution B Apparently, with you I only achieved has been observed. Evolution A is an confusion. Sorry about that. I'll try to do inference; it is not an observable. http://home.planet.nl/~gkorthof/kortho36a.htm (1 of 17)5-7-05 11:53:54 Neo-Darwinian Evolution Really Can't Work! better if I ever treat this subject again. But for this discussion, let me continue to use it and beg your indulgence.

Even though I did not Further you did not observe your own observe my birth, there are others who birth, you can only infer your birth. have and can testify to it. Evolution A, on Furthermore your conception isn't the other hand, is a phenomenon that may observed by anybody: it is just inferred or may not have occurred. You assume it based on naturalistic theories! So there is has; I am agnostic on the matter. Whether no imperative to account for it. or not it has occurred is, in fact, a key point of divergence between evolutionists and creationists. There is no imperative to have a theory to explain Evolution A, because it was not observed and we don't even know that there is such a thing. If we had a theory that could account for Evolution A, there would be reason to give that concept some serious consideration. But there is no such theory. I have seen the argument stated often, that even if there are defects with neo-Darwinian theory, it's the best theory we have to explain the evolution of all life from a single simple ancestor. That's not a very compelling argument to one who questions Evolution A. The distinction between these two (1) The distinction is vague: you only (1) The distinction is not vague precisely meanings of evolution is often ignored by mention the extremes of the scale. But the because I am dealing with the extremes, those defending neo-Darwinian evolution, extremes are no problem. The question is: which you acknowledge is no problem. but the distinction is critical. The claim is where does micro stop, where does macro You are taking the discussion off track. We made for Evolution A, but proof is often start? How many species are allowed to be are not writing a treatise on macro- and limited to Evolution B. The implication is produced by microevolution?
