Wikipedia suggests that the simplest way of understanding what makes a species is whether a group of organisms is capable of interbreeding and producing fertile offspring - will that do for you? I suppose it is possible that a Great Dane could still manage to breed with a Chihuahua, but not without difficulty - haha! I daresay that dog breeders could deliberately create some breeds where it was no longer physically possible for them to breed. I realise that this would not really constitute a new species but my point is that if a divergence and difference like the Great Dane and Chihuahua can be artificially engineered by man in only a few thousand years then given a billion years natural selection can diverge a species into two.

But, I still wonder why life is opposed to physical forces, as > Pirsig asks. His answer: DQ pulling/pushing towards betterness I think that Darwin's 'natural selection' is more or less the same idea as Pirsig's 'dynamic quality', the phraseology being different only because they originate out of different scholarly disciplines. > [P] > If evolution simply means change, yes, things change. No argument there. I think evolution means not merely change but change for the better resulting in increased organisation. The question is, "Why?" Answer - for immortalities sake! Freddy Mercury sang with pathos: 'Who wants to live forever?' Well i do! However experience tells me i will die and i would like the option to voluntarily check out when the going gets too tough and i can no longer fend for myself. All life strives to survive and persist and, in the face of hazard, to reproduce and further continue. This is my most fundamental nature and if i ask 'why' it is only because i seek better ways to survive. My religious upbringing, born out of the natural advantages of working with others towards a common goal, assured me that the path to life everlasting was to serve the good personified in God - but my own experience has led me to the conclusion that their figurehead was merely a fiction. > [P] > Are not chance mutations fundamental to the creation of changes Darwinian > theory attempts to explain? That's what I meant by "creative role." Yes, hazard is around every corner but the title of Darwin's famous book is 'On the Origin of Species By Means of Natural Selection'. There are deep connections in the notions of chance as randomness, chance as opportunity, chance and choice, election and selection; it's damned bad luck to end up sitting on a hot stove but its our long history of natural selection that makes us get off there pdq and without a second thought. [P] > No doubt. What about a sunset? A flower? An elegant theory? This is a whole other topic really but i do think the meaning and significance of art is connected with the idea of persistence also. > [P] > > > Etc.

Sounds like it will be a really interesting book which i intend to buy and read. I dont have very firm political views and find it difficult to confidently enter political discussions but this book looks like it will give a good insight into macro-economics and what makes the human world go around. Thanks for bringing it to my attention. -KO 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/
