Resumen:
The purpose of this
study is to develop discriminant functions for sex estimation in
hunter-gatherer South American populations, using humerus metric
variables. Three Late Holocene aboriginal population samples were
selected from: a) South Patagonia (n= 64), b) Northeastern Patagonia
(n= 47) and c) Northeastern Pampa and Entre Ríos (n= 35). Only those
individuals showing pelvic or cranial diagnostic structures were
included, in order to obtain reliable and independent sex estimation.
Six humeral variables were measured (Maximum Length, Epicondylar
Breadth, Vertical Diameter of Head, Maximum and Minimum Diameter at
Midshaft and Minimum Diaphyseal Circumference) and discriminant
functions were generated from them through stepwise forward method,
which selected different combinations of these variables for each
sample. In order to assess the accuracy of estimations, both pelvic and
humeral sex results were compared. Cross-validation percentages of
correct sex assignations were high, ranging between 82 and 100 percent.
In turn, other functions were tested, generated from different
populations worldwide, and results for the three samples showed mostly
lower percentages. Therefore, it is concluded that Southern-South
America population-specific standards were obtained through this method,
allowing for reliable sex determination in samples from the studied
areas.
