[Aztlan] Rats again

[Nick Hopkins]

I just had a look at Wikipedia (ALWAYS a reliable source...), and  
"true rats" are Old World (Asian origin) species that spread around  
the globe with commerce, mainly through European vessels.  So there  
weren't any "rats" in precolombian Mesoamerica.  I suspect the  
confusion arises in the translation of Spanish ratón, which means  
"mouse", not "rat" (rata).
