The effect of dietary adaption on cranial morphological integration in capuchins (order Primates, genus Cebus).

A fundamental challenge of morphology is to identify the underlying evolutionary and developmental mechanisms leading to correlated phenotypic characters. Patterns and magnitudes of morphological integration and their association with environmental variables are essential for understanding the evolu...
