2. Our current perception of the
settlement of the Americas (last decades):
people was present in the New World prior to Clovis (Dillehay, 1997);
a Beringean coastal route was used by the newcomers instead of an
interior corridor (Dixon, 2001);
the lithic industry and subsistence patterns of the pioneers varied
considerably from region to region (Kipnis, 1998; Roosevelt et al., 2002;
Neves & Cornero, 1997);
the first Americans looked very different from late and nowadays
Native Americans (Neves & Pucciarelli, 1991).

Contrary to this view, Hrdlíčka’s original assertion:
All Native Americans can be
accommodated within one single
cranial morphological range
DNA diversity of present Native
Americans suggests that the continent was
peopled by humans pertaining to only one
biological stock (Merriwether et al., 1995;
Bonatto and Salzano, 1997; Silva et al.,
2002; Fagundes et al., 2008; Goebel et al.,
2008) apparently supporting Hrdlíčka’s
original assertion.

36. Methods
Multivariate comparisons by means of Principal Components Analysis
(PCA) & General Discriminant Analysis (GDA);
Males & Females analyzed together;
Double Z pooled standardization: all cases and variables were normalized;
Correction of sexual dimorfism and size variation.
Replacement of missing values by general means

52. Conclusions
Dual differentiation of Serra da Capivara’s sample can not be attributed
to sexual dimorfism;
One group (in the right side of the PCA) represented by specimens from
the early Holocene and other group (in the left side of the PCA) by
specimens from middle and late Holocene*;
Absence of intermediary morphologies: same scenario observed in
others regions of South America;
Compability with the idea that New World was occupied by two
morphologically distinct populations. Sample from Toca do Paraguaio
show that both morphologies were present in the America between
8.0 – 9.0 kyr BP.
