          Abstract

          Recientes cambios en la estructura del debate sobre el poblamiento americano incluyen la utilización de técnicas sofisticadas de análisis, la aceptación de edades bastante mayores a 12.000 años radiocarbónicos y la recuperación de materiales en una variedad amplia de contextos. Lamentablemente, esto no implica que la acumulación de información en América del Sur avance en forma eficiente, pues se sigue apelando a casos a la vez ambiciosos y ambiguos como los de Arroyo Vizcaíno, en Uruguay o Vale da Pedra Furada, en Brasil. Por otra parte, por distintas razones, tampoco es útil la tendencia a utilizar ciertos criterios estandarizados de aceptación de sitios. La evaluación de los sitios más antiguos de una región debe reflejar una tensión entre ser estrictos -para no aceptar cualquier cosa- y ser amplios -para no perder casos potenciales-. No se puede minimizar la importancia de la tafonomía en estas discusiones.

          The debate about the peopling of America has been significantly transformed in recent years, mainly due to the increasing use of sophisticated analytical techniques, the recovery of relevant information at a variety of contexts, and the acceptance of ages older than 12,000 radiocarbon years. Sadly, information for South America is still not always efficiently produced. Ambiguous but ambitious claims from places like Arroyo Vizcaíno, in Uruguay, or Vale da Pedra Furada in Brazil, are still prominent. Even so, it must be said that the classic acceptance criteria used to validate sites are no longer useful. The discussion of the older sites in a region should reflect a tension between being strict (to avoid accepting wrong claims) and being broad (to retain potentially useful cases). The importance of taphonomy in these discussions cannot be minimized.

          The late Pleistocene dispersal of modern humans in the Americas.

          When did humans colonize the Americas? From where did they come and what routes did they take? These questions have gripped scientists for decades, but until recently answers have proven difficult to find. Current genetic evidence implies dispersal from a single Siberian population toward the Bering Land Bridge no earlier than about 30,000 years ago (and possibly after 22,000 years ago), then migration from Beringia to the Americas sometime after 16,500 years ago. The archaeological records of Siberia and Beringia generally support these findings, as do archaeological sites in North and South America dating to as early as 15,000 years ago. If this is the time of colonization, geological data from western Canada suggest that humans dispersed along the recently deglaciated Pacific coastline.

            Pleistocene cave art from Sulawesi, Indonesia.

            Archaeologists have long been puzzled by the appearance in Europe ∼40-35 thousand years (kyr) ago of a rich corpus of sophisticated artworks, including parietal art (that is, paintings, drawings and engravings on immobile rock surfaces) and portable art (for example, carved figurines), and the absence or scarcity of equivalent, well-dated evidence elsewhere, especially along early human migration routes in South Asia and the Far East, including Wallacea and Australia, where modern humans (Homo sapiens) were established by 50 kyr ago. Here, using uranium-series dating of coralloid speleothems directly associated with 12 human hand stencils and two figurative animal depictions from seven cave sites in the Maros karsts of Sulawesi, we show that rock art traditions on this Indonesian island are at least compatible in age with the oldest European art. The earliest dated image from Maros, with a minimum age of 39.9 kyr, is now the oldest known hand stencil in the world. In addition, a painting of a babirusa ('pig-deer') made at least 35.4 kyr ago is among the earliest dated figurative depictions worldwide, if not the earliest one. Among the implications, it can now be demonstrated that humans were producing rock art by ∼40 kyr ago at opposite ends of the Pleistocene Eurasian world.

              Paleoindian settlement of the high-altitude Peruvian Andes.

              Study of human adaptation to extreme environments is important for understanding our cultural and genetic capacity for survival. The Pucuncho Basin in the southern Peruvian Andes contains the highest-altitude Pleistocene archaeological sites yet identified in the world, about 900 meters above confidently dated contemporary sites. The Pucuncho workshop site [4355 meters above sea level (masl)] includes two fishtail projectile points, which date to about 12.8 to 11.5 thousand years ago (ka). Cuncaicha rock shelter (4480 masl) has a robust, well-preserved, and well-dated occupation sequence spanning the past 12.4 thousand years (ky), with 21 dates older than 11.5 ka. Our results demonstrate that despite cold temperatures and low-oxygen conditions, hunter-gatherers colonized extreme high-altitude Andean environments in the Terminal Pleistocene, within about 2 ky of the initial entry of humans to South America.
