Resumen:
The aim of this work is to assess shape variation in Patagonian stemmed projectile points related to spatial and environmental factors by means of geometric morphometric and multivariate methods. The sample includes over 1000 projectile points from continental and insular Patagonia assigned to Middle-Late and Late Holocene. Previous research showed a trend of shape change related to latitudinal axis, but no information was available to some areas, especially Grande Island of Tierra del Fuego. With the purpose of extending our analysis to overall Patagonia and taking advantage of the new data set available, we focus on the correlation between environmental variables (rainfall, temperature, biomass, etc.) and morphological change. The results obtained allow discussing the role of space, environment, and resource availability in technological decision making, emphasizing the comparison between wet and dry areas. Besides authors? own research and published literature revision, most of the tips come from a broad survey program of museum collections.
