Is anyone aware of any studies done that show the effectiveness of using linguistics as a means of identifying trade between civilizations. I'll provide this example for what I mean:
I have been told that there are trace amounts of tobacco and cocaine in some Egyptian mummies. Let's assume for a moment that the Egyptians were able to get ahold of tobacco and cocaine through trade routes. As it is something that only grows in the Americas, wouldn't they have to be able to ask for these products. Wouldn't they have to use a name that the growers recognize? Doesn't it make sense that the Egyptians would use the name provided, instead of create a new one?
If they use that name, shouldn't we find it in Egyptian records, somewhere?
I admit to being more of a "fan" of Linguistics than anything, so if my question is rudimentary, I apologize.
