For goodness sake Snail. I did not imply, state or express in anyway whatsoever, nor do I think it, that the purpose of evolution is to produce beauty on earth. In fact, I get fed up of having to keep telling you that evolution has no purpose, no direction, no drive towards complexity or greater perfection, no guiding hand either within, without or Beyond, in fact no driving force at all. The beauty in nature that all but the dullest and most abject of minds can discern is a serendipitous by-product of evolution, no more. As for my having told you to bugger off, I did it politely and metaphorically, treading so gently as to prevent you from noticing, my usual modus operandi, as all here know. Toujours la politesse it is avec moi, and it shall remain so on this occasion despite your attempts to be vexatious (again).
