Why has this thread desended into a slanging match? What exactly is being gained by this?

As for the origions of pipes (note that most pipers that I know seldom if ever refer to pipes as bagpipes which might go some way to explain lack of written reference)who knows, perhaps they evolved the same way as farming did - all at once all over the globe - (there is evidence to suggest that farming as a practice started globally within a very short time space). Its a good idea so why should it be assumed the pipes had a liniar development? Just a thought.
