Skeletal evidence of the ethnic cleansing actions in the Free City of Danzig (1939-1942) based on the KL Stutthof victims analysis.

In the early days of World War II, many of the prominent and influential people of Polish nationality from the Free City of Danzig were arrested by the Germans and sent to the nearby concentration camp KL Stutthof. Nearly a hundred of them died within the next seven months upon their arrival, and were buried in a clandestine mass grave in a nearby forest. However, the exact nature of their death is unknown, as it is unclear what the attitude of the aggressors was toward the victims. We do not know whether there was only one executioner or there were several assassins, nor if the killing methodology was consistent with the other state-regulated executions. The studied material represents the commingled remains of a minimum thirty-four people, possibly all male, aged from under eighteen to over sixty at the time of death. Perimortem traumatic lesions are shown mainly on the skull bones. We asked whether the perimortem trauma lesions visible on the victims' skeletons could be informative on the cause and manner of their death. Our results show the prevalence of the perimortem trauma inflicted by a blunt object are on the parietal bones above the Hat Brim Line (HBL), which is commonly associated with a violent attack. The gunshot trauma was usually localized on the occipital bone or posterior parietal, which could indicate a shot to the back of the head, and this was commonly encountered during executions. No signs of defensive injuries can be explained either by restraining of the hands or by a surprise attack. The abundance and variability of the trauma type can be evident of multiple assailants. Moreover, the multiple impact points detected on several crania prove unnecessary overkill and brutality, which reflects the personal attitudes of the executioners towards the victims.

Phase II spatial patterning of vulture scavenged human remains.

This project expands on a pilot study by Spradley, Hamilton, and Giordano (2012) that investigated the patterns and effect of vulture scavenging of human remains, with special focus on the effect of microenvironments. Five donated bodies from the Willed Body Donation Program at Texas State University were placed in various locations at the university's Forensic Anthropology Research Facility (FARF). The bodies were monitored by motion capture cameras and after each vulture scavenging event the dispersal and location of the bodies' skeletal elements were mapped with a high accuracy GPS unit. The degree and direction of dispersal by vultures were then analyzed with GIS. Phase II revealed that vultures will begin scavenging at variable times, will continue to return to and move remains after a body has been skeletonized, and tend to move remains from higher elevations to lower elevations. The data also suggested that vultures may scavenge in larger groups (n > 20) in cooler temperatures, but in warm to hot temperatures they may scavenge more frequently in smaller groups (n ≈ 5). Future directions for vulture scavenging profiles are briefly discussed.

Morphological variation among late holocene Mexicans: Implications for discussions about the human occupation of the Americas.

OBJECTIVES: Cranial morphology has previously been used to estimate phylogenetic relationships among populations, and has been an important tool in the reconstruction of ancient human dispersals across the planet. In the Americas, previous morphological studies support a scenario of people entering the Americas and dispersing from North America into South America through Meso America, making the Mexican territory the natural funnel through which biological diversity entered South America. MATERIALS AND METHODS: We explore the cranial morphological affinities of three late Holocene Mexican series, in relation to ancient and modern crania from North and South America, Australo-Melanesia, and East Asia. Morphological affinities were assessed through Mahalanobis Distances, and represented via Multidimensional Scaling and Ward's Linkage Cluster analysis. Minimum FST values were also calculated for each series. RESULTS: Our results show Mexican groups share morphological affinities with the Native American series, but do not cluster together as would be expected. The minimum FST estimates show between-group variation in the Americas is higher than the Asian or Australo-Melanesian populations, and that Mexican series have high between-group variance (FST = 0.124), compared to the geographically larger South America (FST = 0.116) and North America (FST = 0.076). DISCUSSION: These results show that the Mexican series share morphological affinities with the East Asian series, but maintains high levels of between-group variation, similar to South America. This supports the suggestion that the high phenotypic variation seen the Americas is not a result of its size, as it can be found in more constricted areas, such as the Mexican territory.
