Abstract

ORQUERA, Luis Abel. El poblamiento temprano de Tierra del Fuego. Intersecciones antropol. [online]. 2022, vol.23, n.1, pp.141-151. ISSN 1850-373X.  http://dx.doi.org/https://doi.org/10.37176/iea.23.1.2022.654.

A recent publication suggests that archaeological research carried out over the last 45 years on the shores of the Beagle Channel, Tierra del Fuego, has been biased by insufficient information and by preconceptions that blocked the identification of early sites. The focus is the relationship between the first and second components of Túnel I and Imiwaia I sites. It had been proposed by the current author that the archaeological data indicate an initial population that sporadically penetrated the region from the north of the island, and a later replacement by another population whose expansion was founded on the adaptation to marine life. The recent publication, however, opens up the possibility of a local evolution that would turn the creators of the first component into creators of the second component of the above-mentioned sites. In this reply, previously published data are presented that indicate temporal and tool discontinuities – and therefore also populational ones – between each pair of components. The original publications, therefore, were neither biased nor misinformed.

Keywords : Environmental substrate; Temporal sequence; Technological differences; Evolutionary discontinuity; Marine life adaptation.
