An appropriate example here would be Darwin's finches in the Galapogos, with a few from one population finding their way (or being blown in a storm) to the next island along and founding a new strain that gradually diverged from the original. On this sexual attraction leading to pairing and breeding only within the group, Dawkins'(?) theory is that not only does Dad pass on his long tail genes to his sons, Mum passes on her liking for long tails (that made her pick that particular cock) to her daughters, and a positive feedback loop is set up leading to long-tailed tits that aren't attracted to blue tits or even great tits...
I certainly dont think there will be literally two sub-species develop, but if I imagine a suitably dystopian future I can see a class divide that promotes less cross-fertilization. Some chavs will shag a few chav-nots, but the distribution of genes will be inhibited and each group will diverge enough that you will be able to tell the difference. If you think this is all too far-fetched, I have news for you. I've lived in an around Lincolnshire for 10 years in total, and I can tell you it is already happening! Have you ever seen what they produce in Boston??
You mean those dirty thick-skinned things aren't potatoes? We're possibly into nature v nurture territory. Bring a kid up on a poor diet, sat in front of a TV all day, and a sallow-cheeked moron will result.
Yep... that's Boston. We're into lots of [unknown] territory here. We haven't a clue what will happen next week let alone next millennium, but it's good opportunity to slag off the chavs. I think we have got to hope that the world would react to such changes and prevent them from happening. Dont hold your breath though.
Damnit. Makes me wish I had read Brave New World for my major English assignment instead of just reading summaries.
The summary *is* the story... It is the most over-rated book I have read. I read it following The Big Read that the BBC did. I was shocked at what classics it knocked off the top 10. The basic premiss is the whole story. That is it. 1984 is hard to get into, and doesn't have any sort of happy ending, but it's a great story. Never read The Time Machine but loved the original film - though it probably bears no resemblance to what Wells intended.
Those who are in control actually want this divide to continue; those who one not are too dumb to care. In any case I don't think anything will happen that has not been happening for the last millenia.
