Is this a report of an actual experiment or is it conjecture? Changing surface characteristics of organisms is hardly evolution. Animal breeders do it all the time. Can you conceive of a similar scenario in which a fruit fly becomes a house fly, a horse fly or a dragon fly? That would be evolution. ------------------------------------------------- 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/
