Ralph E. Morrow Distinguished University Professor of Physical Anthropology
Expertise: Miocene hominids, biomechanics, primate comparative and functional morphology, quantitative methods
Bio:
Smith is interested in understanding biological variation in fossil apes and humans, particularly australopithecines and Miocene hominoids. Inferences concerning the life-history, ecology, and behavior of these species from the fragmentary morphology found in the fossil record usually involve comparisons with living species. These comparisons, often based on statistical analysis, also depend upon many assumptions about the nature of adaptation and the process of historical explanation.

'Fantastic, unique experience in 120 degree heat'
 Collaboration with Libyan geologists yields many positives

Dec. 7,
2005 --
 |
| Josh Smith in the Libyan desert. |
They're back! Joshua Smith, Ph.D., assistant professor of earth and planetary sciences in Arts & Sciences, and D. Tab Rasmussen, Ph.D., professor of anthropology, both in Arts & Sciences, are stateside, teaching at Washington University after returning from what is thought to be the first-ever collaborative paleontological expedition between American and Libyan scientists. Smith and Rasmussen were in Libya for just three weeks in August of 2005. They were in the field for only 10 days, and they and their colleagues visited 13 new places that have produced Cretaceous-aged vertebrate fossils. They found fossils of sharks, bony fish, crocodiles and turtles.

Additional Background: At present, Smith's work is divided about equally among two main themes. First,he is involved in studies of applied comparative functional morphology. In this work, he attempts to identify relationships between form and function in living primates that may provide insight into the causes for variations in form among fossil hominids. He is particularly interested in the ecological, behavioral, and life-history implications of differences among primate species in body mass, sexual dimorphism in body mass, neonatal maturity, and in the morphology and biomechanics of the cranio-facial skeleton. His second major area of interest concerns the methods used to draw inferences about the past from the present. In this work, he focuses on the process of paleontological inference itself and asks questions such as "How do we test statements made about the behavior or ecology of extinct species? How much confidence can we have in these inferences?" Much of this work concerns the theory and logic of statistical methods, particularly some of the new comparative methods that attempt to incorporate phylogenetic information into statistical models.
