Even more than in other regions, there is a tendency to observe towards Andean Prehistory throughout a markedly evolutionistic paradigm. In those interpretations could be noticed a final spectre which attempts to foresee everywhere the ethos and social-political character of the 16th century core formations contacted by europeans ?i. e. the ayllu-based chieftanships, and on a greater extent, the Inka State logic?. In addition, this aim also blocks any effort to bring forth social analysis in terms of the own political logic of the societies unearthed by Archaeology, ignoring or dismissing the agency of their individuals.During the so-called Formative Period groups of food producers, characterized by a combined use of agriculture and camelid herding, settled at Tafi Valley as in its nearby zones (Tucuman Province, Argentina). By almost a millennium (250 BC-850 AD), they built and inhabited a landscape consisting of hundreds of isolated multicellular courtyard houses highly scattered all over the valley. The early discovery of a ceremonial mound associated with menhir-like carved stones at valley?s bottom, in turn, allowed a traditional interpretation of the whole society as a kind of emerging ritualistic chieftainship, both symbolically and physically centered in such a spot. However, new discoveries as well as a reevaluation of the current data from the point of view of Clastrean and Poststructural Theories, point out a quite complex social scene. In this paper, those latest archaeological works concerning the political logic underlying Tafi ?centrifugal landscape? will be presented.
