Morphometric analysis of shape differences in Windover and Point Hope archaic human mandibles

The following analysis tests two hypotheses: that there are significant differences in morphology in mandibular shape between the genders amongst Archaic North American Homo sapiens and that there is a significant difference in variance in mandibular shape between Archaic Windover and Point Hope

Scholarcy highlights

  • The following analysis tests two hypotheses: that there are significant differences in morphology in mandibular shape between the genders amongst Archaic North American Homo sapiens and that there is a significant difference in variance in mandibular shape between Archaic Windover and Point Hope
  • A sample made from mandible specimens taken from both populations is subjected to Principal Component Analyses
  • The mancova found that there are no significant interactions between the PC scores in population, sex, or size
  • Significant differences in variance were found between males and females and between the Windover and Point Hope populations
  • Differences in variance observed between the populations are suspected to be due to differences in subsistence strategies and possibly non-masticatory utilizations of teeth
  • Differences in variance between the genders are suspected to be genetic in origin
