Many thanks guys that's certainly some very useful info. I did a bit of digging myself this weekend and came across a couple of good examples - the thalasemia one does seem particularly interesting.
I guess climate change is likely to have a big impact on everything so if anyone has come across some crackers that would be great ( the rise and fall of the wolly mammouth springs to mind). I wonder how long it will be until we see the first confirmed cases of speciation due to global warming - new islands get formed etc?
Also "another someone", you're right about the moth's things come to think of it, that's just an example of selection pressures really so I guess squirrels are too. I've not really been too hot on keeping my definitions tight. With bacteria on the other hand you can develop new resistance mutations in in vitro situations can't you - not just horizontal transfer of availible resistance?
