Trinkaus has been concerned primarily with the biology and behavior of Neandertals and early modern humans through the Middle and Late Pleistocene,in order to shed light on these past humans and to understand the emergence and establishment of modern humans. His work therefore has been primarily concerned with the comparative and functional anatomy,paleopathology,and life history of these past humans. At the same time,because it dominates paleoanthropology,he has been involved in debates concerning the ancestry of modern humans,being one of the first to argue for an African origin of modern humans but with substantial Neandertal ancestry among modern Eurasian human populations.[3][4]
Although his early work emphasized differences between the Neandertals (and other archaic humans) and early modern humans,[5] his work since the 1990s has documented many similarities across these human groups in terms of function,levels of activity and stress,and abilities to cope socially with the rigors of a Pleistocene foraging existence.[6] His research therefore involves the biomechanical analysis of cranio-facial and post-cranial remains,patterns of tooth wear,interpretations of ecogeographical patterning,life history parameters (growth and mortality),differential levels and patterns of stress (paleopathology),issues of survival,and the interrelationships between these patterns.
Research projects
Trinkaus has conducted a series of comparative analyses,with colleagues and students,on the regional functional anatomy of Neandertals and other Pleistocene humans. He has contributed to the direct radiocarbon dating of original human fossils,and through that work to insights into their diets through the analysis of carbon (C) and nitrogen (N) stable isotopes. He has been involved in the primary paleontological descriptions of a number of Middle and Late Pleistocene human remains,of both archaic and early modern humans. The first project was his monograph on the Shanidar Neandertals from Iraqi Kurdistan.[7] Subsequent major projects concerned with early modern humans include the Abrigo do Lagar Velho (Portugal)[8]DolníVěstonice and Pavlov Moravia,Czech Republic,[9]Peştera cu Oase (Romania),[10]Peştera Muierii (Romania),[11] Mladeč(Czech Republic),[12] Tianyuandong (China),[13] and Sunghir (Russia).[14] Additional Neandertal descriptions include those from Krapina (Croatia),[15] Oliveira (Portugal),[16] Kiik-Koba (Crimea),[17] and Sima de las Palomas (Spain).[18] To these can be added Middle Pleistocene human remains from Aubesier (France),[19]Broken Hill (Zambia),[20] and Hualongdong (China),[21] plus late archaic humans remains from Xujiayao and Xuchang (China).[22][23] These paleontological descriptions include both primary data on these fossils and a diversity of paleobiological interpretations of the remains and the Pleistocene human groups from which they derive.
Trinkaus's analyses of early modern human remains,especially those from DolníVěstonice,Pavlov,Lagar Velho and Sunghir,have raised a series of questions regarding the nature and diversity of mortuary practices among these early modern humans.[24][25] And his paleopathological analyses of Pleistocene human remains have raised questions concerning the levels and natures of trauma[26] and developmental abnormalities among these people.[27]
