  Methodologically, the modelling of possible routes have applied several views, such as anthropobiologic morphometric and DNA data (Meltzer 1993, O’Rourke and Raff 2010, Pucciarelli et al. 2003); demographic simulations (Gillam et al. 2007; Steele et al. 1998); and digital modelling of territorial analysis (Anderson and Gillam 2000). The present paper is included in the last mentioned approach. The main goal of this work is to contrast two digital models of terrain accessibility generated for South America (Magnin et al., this volume) against a set of archaeological information on the earliest occupations. Both models have been produced to represent the main ideas prevailing for the ways of access to the continent (terrestrial vs. littoral and riverside), and the assessment of the best adjustment to either of them.
