Phenotypic variation in the human mandible over the last 500 years in the Netherlands
Applying geometric morphometrics methods to quantify the anatomical variation of the mandible, the primary aim of this project is to assess patterns of phenotypic variation across the last 500 years in the Netherlands. The project, in collaboration with Dan Dediu and Scott Moisik from the Max Planck Institute for Psycholinguistics in Nijmegen, and Andrea Waters-Rist from the Laboratory for Human Osteoarchaeology in Leiden, utilizes 3D laser scan data of two Dutch archaeological populations (Alkmaar, AD 1484-1574 and Middenbeemster, AD 1829-1866) and MRI scan data of extant Dutch individuals.
Virtual reconstruction of African hominin fossils
As part of his dissertation, Bosman is working on the reconstruction of two hominin fossil crania from East Africa. The first, Eyasi I, was discovered off the shore of Lake Eyasi, Tanzania in the 1930s and the second, Kabua I, was located in the western shore of Lake Turkana, Kenya in 1959. Both are important in understanding of the evolution and diversity of hominin populations in Africa during the Middle to Late Pleistocene. However, they have remained largely out of discussion and scientific research due to their fragmentary nature. Thus, Bosman uses micro-CT scans of the fossil fragments and a suite of virtual anthropological techniques to reconstruct the crania, providing a starting point for further comparative work and taxonomic assessment. The project is part of a collaboration with Chris Stringer of the National History Museum, London, prospective DFG Center fellow Laura Buck of the University of Cambridge, and colleagues.
