“…Indeed, the results of this experiment are congruent with several studies of archaeological data, which suggest that to fully explain differences in the attributes of stone artifacts across time and space, factors other than raw materials must be invoked (e.g., Sharon, 2008;Clarkson, 2010;Costa, 2010;Smallwood, 2012;Buchanan et al, 2014). In fact, although standard logic has frequently suggested otherwise, on the basis of the results described, it may be more appropriate to rule out other factors prior to attributing differences in lithic assemblages to raw material effects, just as in comparative biology, where internal historical factors are controlled for prior to asserting a prominent role for external factors (e.g., Nunn, 2011).…”

“…Raw material factors have long been considered to exert an influence on the form and composition of lithic assemblages (Goodman, 1944), and the role of raw material has been frequently deliberated over in specific regard to variation within the Acheulean techno-complex (e.g., Isaac, 1977;Jones, 1979;Wynn and Tierson, 1990;Roe, 1994;Schick 1994;Clark, 2001;Noll and Petraglia, 2001;Sharon, 2008;Archer and Braun, 2010;Costa, 2010;Wang et al, 2012; among many others). The suspected link between lithological factors and resultant artifactual form is, of course, a logical outcome of the fact that the medium with which any artisan is working might have properties that affect given outcomes.…”

“…Particular attention was directed to the format of the butt, the angle of any distinct point formed by straight edges and any curves used on the 'blades' forming the point. An assessment was made to see if this 'degree of fit' could be statistically determined using PAST software as in the morphological analysis of bone and stone bifaces from Castel di Guido (Costa 2010), but this option was rejected as this technique 'masks' the individuality of each tool and, due to the presence of imperfections or damage on the tools, a visually 'poor' fit could offer a better statistical value than an exceptionally 'good' fit, if the latter had a partly damaged edge.…”

“…However, what is proposed in this article is not an in-depth study of lithic technology itself, but the presentation of a complementary approach, involving the use of geometric morphometrics and multivariate statistical tests not very often used in Brazilian archaeology (but see Okumura & Araujo 2014), but whose potential has been exploited successfully in several studies abroad (Saragusti et al 2005;Cardillo 2006;Buchanan et al 2007;Castiñeira et al 2009;2011;Franco et al 2009;Archer & Braun 2010;Buchanan & Collard 2010;Costa 2010;Lycett et al 2010;Iovita 2011;Brown et al 2012;Charlin & González-José 2012;Lycett & Von Cramon-Taubadel 2012;Thulman 2012;Wang et al 2012;de Azevedo et al 2013;Lycett & Eren 2013;Charlin et al 2014;Davis et al 2015;Fox 2015;Cardillo et al in press). The use of multivariate statistical methods applied to geometric morphometrics data might help elucidate old questions about the characterization of the Umbu tradition, possibly clarifying the meanings related to changes in the morphology of bifacial points over time, the chrono-spatial relationships among different sets of points, among other issues.…”
