* I can't see where I invoked "something is evidence if enough people 
say it is so," I was just suggesting that rafting depends on winds and 
currents, and that if (just basing this in the instances brought up in 
this thread) the rafting hypothesis was spurious, there'd be as many 
eastbound as westbound events.

The vicariance idea that adjacent biotas don't tend to mingle is a 
useful null hypothesis, but null hypotheses are sometimes falsified.

And there is the expression "What about Canada, eh?" - our biota is all 
postglacial dispersants, and while there are instructive differences 
between the character of the biotas on deglaciated and unglaciated 
territory, we do have quite a few species.
