Is the Late Neandertal mandibular sample from Vindija Cave (Croatia) biased?

The late Neandertal sample from Vindija (Croatia) has been described as transitional between the earlier Central European Neandertals from Krapina (Croatia) and modern humans. However, the morphological differences indicating this transition may rather be the result of different sex and/or age compositions between the samples. This study tests the hypothesis that the metric differences between the Krapina and Vindija mandibular samples are due to sample bias. Mandibles are the focus of this paper because past studies have posited this region as particularly indicative of the Vindija sample's transitional nature. The results indicate that the metric differences between the Kropina and Vindija mandibular samples are not due to sample bias. This conclusion is consistent with an earlier analysis of sample bias for the Vindija supraorbital sample.
