A finch is a finch is a finch -- like those white and brown moths in England who are cited as evidence of evolution. But, my question is: how does a finch become an eagle? Evolution says over a eons and millions of tiny little changes. Except, the tiny little changes haven't been found in the fossil record. Instead we see giant leaps, "explosions" and "punctuated equilibriums." ------------------------------------------------- This mail sent through IMP: http://horde.org/imp/ Moq_Discuss mailing list Listinfo, Unsubscribing etc. http://lists.moqtalk.org/listinfo.cgi/moq_discuss-moqtalk.org Archives: http://lists.moqtalk.org/pipermail/moq_discuss-moqtalk.org/ http://moq.org.uk/pipermail/moq_discuss_archive/
