RESUMENEl objetivo de este artículo es dar a conocer los primeros resultados de las excavaciones en la cueva de Valdavara (Becerreá, Lugo), prestando especial atención a las dataciones radiométricas que la sitúan entre los pocos yacimientos gallegos que han arrojado fechas correspondientes al Paleolítico Superior. La excavación realizada en el año 2007 permitió documentar dos localizaciones arqueológicas en el marco del mismo sistema cárstico (Valdavara 1 y Valdavara 2). El sondeo iniciado en Valdavara 1 ha permitido identificar hasta el momento dos conjuntos estratigráficos: un conjunto superior correspondiente a la Prehistoria reciente y un conjunto inferior (nivel 4) en el que se han obtenido las fechas del Paleolí-tico Superior final. En Valdavara 2 se encontró un conjunto de restos humanos de la Edad del Bronce.
The D4500 (Skull 5), dated 1.8 Mya., is the most complete fossil within the set of five skulls found in Dmanisi, Georgia, as well as any other fossils associated to contexts of occupation of the early Pleistocene. Its discovery has brought forward the debate of the plurality of species, not just at the beginning of the Homo genus, but for much of its evolution. The Skull 5 fossil presents a mixure of primitive and derivates characters associated to the Homo erectus and Homo habilis sensu lato. Based on the data referring to the five skulls researchers have considered the hypothesis of a single evolving lineage of early Homo as a mode to explain the great variation range of the Dmanisi fossils, similar to the range found in habilines. In other words, it is an explanation that reiterates the existence of only one unique species in the early of the Homo genus: the Homo erectus in a sensu lato. Our work consists of evaluating such supposition through the calculation of the coefficient of variation, which was estimated from the referred set and compared to those from already known species. Results achieved did not support the thinking that one unique species was able to bear all fossils of the early of Homo genus.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
