Pecos revisited a modern analysis of Earnest Hooton's The Indians of Pecos Pueblo /
Abstract (Summary)
The extensive data recorded by Earnest Hooton (1930) during his years of
work on the analysis of the remains recovered from Pecos Pueblo provides an
excellent database for reconsidering his conclusions within a modern context.
The first issue addressed in re-examining Hooton’s data relates to the sex
estimations made for the Pecos sample. Researchers, specifically Ruff (1991),
questioned the highly biased sex ratio that Hooton reported for the sample. Using
the craniometric and postcranial metrics data that Hooton collected it was possible
to re-evaluate Hooton’s sex estimations by utilizing discriminant function
analysis in order to establish a more accurate sex ratio for the sample. The
discriminant function analysis showed that in fact, as Ruff (1991) suggested,
Hooton and Todd probably overestimated the number of males in the sample.
In addition to the sex estimations, the biological distance of the Pecos
sample is examined. In his analysis Hooton merged the sample into groups by
dividing the glaze chronology into larger groupings in order to maximize the
sample sizes. A biological distance matrix is constructed using both craniometrics
and cranial nonmetric traits in order to determine the validity of Hooton’s
divisions, and to analyze the population structure. The distance matrices from
these two types of data give contradictory results about the temporal trend in the
population make-up at Pecos.
Health and stress were examined by looking at changes in asymmetry and
sexual dimorphism from the initial occupation of the pueblo to the introduction of
ii
Europeans and eventual abandonment of the pueblo. The asymmetry analysis
revealed the greatest amount of fluctuating asymmetry for all traits combined in
the earliest time period, with the amount of FA decreasing through time. The
results of the sexual dimorphism analysis revealed a similar pattern to the
asymmetry results. The mean MDI in the early time period was the least for all
significant traits, and the MDI generally increases through time, with the MDI
being greatest in the latest time period for all measurements except the
anterior/posterior midshaft of the femur.
Next, migration is examined by calculating the surplus variation present at
Pecos by comparison to the sample from the Larson site, a population known to
have little variation. Variation is significantly greater for all time periods of the
pooled sexes and throughout the male samples. The greatest variation for pooled,
males and females exists in Glaze IV during the building the large pueblo and the
establishment of Pecos as a major trading center between the Puebloan and Plains
populations, when many people must have been arriving at the pueblo. The
variation among the females is significantly greater in the early time periods, but
significantly less in the later time periods. Overall, the female variation is less
then or equal to the male variation across all time periods and never exceeds the
male variation. The surplus variation analysis will be used to give an indication
of the migration pattern at the pueblo. The paleodemography of Pecos is the final
analysis performed on the sample. The paleodemography of Pecos confirms much
of the previously mentioned patterns from the earlier analysis of the health and
stress patterns seen at Pecos. The early time period appears to be most different
iii
from the middle time period, but not different from the late time period. It is
apparent from the results of the analysis that the construction of the pueblo
created a significant change in the people of Pecos. However, the significant
variation among the time periods suggests that migration is also likely influences
the results of the paleodemography.
