| Outline of Final Research Achievements |
Some technical difficulties always disturb our examinations of morphological features to support for a hypothesis on ancestor-descendant relationship of a given fossil and extant taxa. One of them is an evolutionary fluctuation in size even for a same lineage, i.e., phylogenetic allometry. This allometry effect prohibits us to compare a morphological feature in fossil and extant specimens. This study uses Geometric Morphometry to extract a common allometry trend of papionins and to show variation in shape. We develop a method to visualize three-dimensional surface of these shape variation. This method allows us to compare and evaluate features in shape between extant and fossil specimens.
