The objective of this paper is to present a holistic methodological design addressed to analyze the socio-economic dynamics of fisher-hunter-gatherer societies of the Beagle Channel region (Southern Tierra del Fuego, Argentina). The method consists on the recovery, identification and study of organic and inorganic residues present on stone tools as well as in archaeological sediments in order to verify if the residues are the consequence of the use of the artifacts as tools or the result of the artifact contamination. It includes several lines of research such us phitolytic analysis, use-wear analysis, blood tests and organic material concentrations within the archaeological layers. We started to apply the approach to an archaeological sample recovered from Lanashuaia I archaeological site, with a XIXth Century date. The analysis performed showed: a) significant variations in phytolith distribution between different areas and layers of Lanashuaia I; b) use wear traces of bone and hide working and c) positive results in some blood tests. These results and the techniques are discussed to highlight the problems and possibilities of each line of research.
