'Erik Trinkaus', PhD, (
December 24,
1948) is a prominent
paleoanthropologist and expert on
Neanderthal biology and
human evolution. Trinkaus researches the
evolution of the
genus ''
Homo sapiens'' and recent
human diversity, focusing on the
paleoanthropology and emergence of late
archaic and early modern
humans, and the subsequent evolution of '
anatomically modern' humanity. Trinkaus is a member of the
National Academy of Sciences, a contributor to publications including ''
Natural History'' and ''
Scientific American'', and is frequently quoted in the popular
media. Trinkaus is the Mary Tileston Hemenway Professor of Physical Anthropology at
Washington University in St. Louis
Education
Trinkaus received his bachelor of arts degree in
Art History and
Physics from the
University of Wisconsin-Madison, and his master's and PhD degrees in
anthropology from the
University of Pennsylvania, the latter in
1975.
Scientific influence
Trinkaus' research findings and analyses of archaeological materials have made significant contributions to the understanding of early modern
human biology, particularly in the areas of Neanderthal
extinction and
intelligence, the
mitochondrial Eve theory, and the contributions of Neanderthal
DNA to the
human gene pool.
Trinkaus' research emphasizes the
biological implications of behavioural shifts that could have been caused by interactions between Neanderthals and anatomically modern
Pleistocene humans. His research addresses the 'origins of modern humans' debate, the interpretation of the archaeological record, and patterns of recent human anatomical variation, principally through his analysis of human
fossil remains. His research involves
biomechanical analysis of
crania and post-cranial remains, respiratory and thermal adaptations, interpretations of ecogeographical patterning, evaluations of neuroanatomical evolution, life history parameters, and differential levels and patterns of stress, and interrelationships between these anatomically-based patterns.
In
1999, Trinkaus and his colleagues documented that Neanderthals roamed central
Europe as recently as 28,000 years ago, the latest date yet established for Neandertal fossils worldwide.
As findings of potentially
hybrid Neanderthal/modern fossils in places like
Portugal have emerged in recent years, Trinkaus has broadened his research to include the complex patterns of
human evolutionary change through the Early and especially Middle
Pleistocene, especially with regard to the diversity,
paleobiology and
behaviour of early modern humans.
Research projects
Trinkaus' recent research has primarily focused on three projects. The first involved the early
Upper Paleolithic (ca.25,000 B.P.) child's skeleton from the
Abrigo do Lagar Velho in Portugal, a specimen which indicates some degree of admixture between the Neandertals and early modern humans in
Iberia. The second concerns the largest known sample of early modern human remains, of the Paleolithic
Gravettian culture, from the
Dolni Vestonice and in the vicinity of Pavlov in southern
Moravia,
Czech Republic, dated between 25,000 and 27,000 B.P. The third began in
2002 with the discovery in
Romania of early modern human remains in the
Pestera cu Oase, dated to 35,000 B.P., which represent the earliest modern humans yet discovered in Europe.
