| Abstract | espanolLos modelos bioantropologicos y arqueologicos proponen cambios en la demografia, en la organizacion social, en las dinamicas poblacionales y en las redes de interaccion social entre los grupos cazadores-recolectores del norte de la Patagonia y del sur pampeano durante los ultimos 1000 anos. El objetivo de este trabajo es explorar, desde la perspectiva de la antropologia dental, si los individuos recuperados en el curso inferior del rio Colorado (transicion pampeano-patagonica oriental, provincia de Buenos Aires), inhumados durante el Holoceno tardio (ca. 3000-250 anos AP), pertenecieron a diferentes poblaciones biologicas o si, por el contrario, compartieron un pool genico comun a lo largo de ese periodo. Para alcanzar este objetivo se realizaron analisis metricos de la denticion permanente de 21 individuos adultos de ambos sexos, procedentes de tres sitios arqueologicos. Los resultados indican una similitud en la dispersion de los valores obtenidos, lo que permitiria inferir cierta continuidad fenotipica. En este sentido, no se observan segregaciones claras entre grupos de individuos, de manera que es posible plantear que no habrian existido divergencias biologicas entre los grupos humanos que inhumaban a sus ancestros en el area durante todo el lapso considerado. Estos datos contrastan con la informacion generada en areas vecinas (p. ej., Pampa occidental), lo que indicaria que durante el Holoceno tardio final (ca. 1000-250 anos AP) se habrian desarrollado diferentes procesos y dinamicas poblacionales (p.ej., regionalizacion) a nivel macro-regional. EnglishBioanthropological and archaeological models propose changes in demography, social organization, population dynamics, and social network interactions among hunter-gatherer groups of northern Patagonia and southern Pampas over the last 1000 years BP. Following this argument, the aim of this paper is to examine, from a dental anthropological perspective, whether the individuals recovered in the lower course of the Colorado river (eastern Pampean-Patagonian transition, Buenos Aires province, Argentina), buried during the late Holocene (ca. 3000-250 years BP), belonged to different biological populations or, on the contrary, whether they shared a common gene pool throughout this period. To achieve this goal, dental metrics were performed on adults from both sexes, recovered from three archaeological sites. The results indicate a similarity in the dispersion of the values obtained, which would allow the inference of certain phenotypic continuity. In this sense, no clear segregations among groups of individuals are observed, so that it is possible to argue that biological differences would not have existed among the human groups that buried their ancestors in the lower course of the Colorado river during the period considered. These data contrast with the information generated in neighboring areas (e.g., western Pampas), indicating that during the final late Holocene (ca. 1000-250 years BP) different processes and population dynamics (e.g., regionalization) developed at a macro-regional level. |
