But basically, the gist is this:
There was a dig in a place in the Andes called "the Wacheqsa Sector at Chavín de Huántar." Based on the dig, we have identified five distinct areas within the sector, each with its own function for the people who lived there. Among these areas were waste dumps, social spaces with lots of buildings, and these weird platforms. The people here continued to develop their settlement over 700 years, between 1200 and 500 BC, with most of the work taking place over the last 400 years: to complete the bulk of work on the Temple and to make Janabarriu ceramics.
Scattered around in these areas we found a lot of pottery we didn't expect because it doesn't fall into the recognized style of the people who lived there. But why? We think it's because, for various reasons, people from areas surrounding this sector mixed with these people and brought their own pottery styles here. This paper is about why and how that happened.
Is that correct?
So well informed I don't know where the truth begins.
