Prentiss et al. (2003) have argued for a relatively recent, short (1600-1100 B.P.), and noncontinuous occupation of large villages and large housepits on the British Columbian Plateau. They argue that these developments resulted from climatically induced resource impoverishment in the region. I maintain that their database is inadequate for such conclusions and that their interpretations are in conflict with dates that 1 obtained from large housepits as well as with the distribution of early point styles (dating from 1200-4800 B.P.) that concentrate in the rim middens of large and medium-sized housepits. These data indicate that large villages and housepits that emerged by 2600 B.P, or earlier, were continuously occupied and corresponded more to the development of collector-based technologies rather than any climatic deteriorations or the introduction of the bow and arrow. Prentiss et al. (2003) han argumentado que la ocupacion de grandes aldeas y grandes estructuras semi-subterraneas en el altiplano de la Columbia Britanica es relativamente reciente y corta (1600-1100 a. de P.). Arguyen que estos desarrollos fueron el resultado de un empobrecimiento climdticamente inducido de recursos en la region. Yo sostengo que su base de datos es inadecuada para llegar a tales conclusiones y que sus interpretaciones entran en conflicto con las fechas que he obtenido de grandes estructuras semi-subterraneas, y tambien con la distribucion de estilos de puntas tempranos (que datan de 1200-4800 a.de.P.), los cuales se concentran en las depositos de basura de las estructuras semi-subterraneas grandes y medianas. Estos datos indican que las grandes aldeas y estructuras semi-subterrdneas que surgieron hacia 2600 a.de.P o mas temprano, fueron usadas continuamente, y corresponden rods bien al desarrollo de tecnologias basadas en la recoleccion que a cualquier deterioro climatico o a la introduccion del arco y la flecha., Recently, William Prentiss et al. (2003) reported a series of radiocarbon dates that call into question a relatively early and long-lasting chronology for the large-scale village aggregations and residential corporate [...]
