I'm discovering the joys of research, particularly when it comes to assumptions getting crushed, leading to more research.
My example: I've been doing research on masks in North American arctic-Inuit culture. In my earlier research it's easy to see information that says about Inuit being around since 5000 BCE or more. Well, as I discovered, there were peoples earlier than that-but they weren't called Inuit. Enter the Dorset and Thule, two different cultures that chronologically predated the Inuit. Seems that the Dorset are founded back to around 2000 BCE or later. And even in their legends, they refer to another people who they said they pushed out the area-though apparently they are more legend, and not a lot of scientific basis yet.
So, what now? Well now I get to pretty much chew up my chonology of Inuit and work on the Thule and Dorset cultures as they pertain to their masks, and seeing what I can find out. At first I was understandably frustrated, but then I looked at it as a way of just having more information on the culture and timeline in question, which is turn will lead to more information-so really it's all good.
Hopefully the Dorset and Thule culture research gives me some good information to work with.
