The "Northern Caddoan Area" was not Caddoan

In this paper I will challenge one of the major unexamined assumptions in the archeology of Eastern North America, the assumption that the Arkansas River Valley and Ozark Highland regions of eastern Oklahoma and western Arkansas, the so-called northern Caddoan Area, was the home of Caddo people who were closely related culturally and linguistically to the Caddo people of southwest Arkansas, northwest Louisiana, east Texas, and southeast Oklahoma. I will propose, instead, that the archeology of this locality is much more complex and interesting than the conventional wisdom would have it. What is involved here, I suggest, is not one region but parts of three, with three culturally and biologically distinct populations. Furthermore, I will propose that Spiro, the key site in this locality, is actually two sites, one Caddoan, the other Mississippian.
