Mosaic evolution describes different rates of evolutionary change in different body units. Morphologically these units are
described by more relationships within a unit than between different units which relates mosaic evolution with morphological
integration and modularity. Recent evidence suggests mosaic evolution at the human basicranium due to different evolutionary
rates of midline and lateral cranial base morphology but this hypothesis has not yet been addressed explicitly. We this hypothesis
and explore how mosaic evolution relates to modular development. Evolutionary data sets on midline (N = 186) and lateral (N = 86) basicranial morphology are compared with 3D data on pre- and postnatal basicranial ontogeny (N = 71). Our results support the hypothesis of mosaic evolution and suggest a modular nature of basicranial development. Different
embryological basicranial units likely became differently modified during evolution, with relatively stable midline elements
and more variable lateral elements. In addition, developmental data suggests that modularity patterns change throughout ontogeny.
During prenatal ontogeny lateral basicranial elements (greater sphenoid wings and petrosal pyramids) change together compared
with the midline base. Close to birth the greater sphenoid wings keep a spatially stable position, while the petrosal pyramids
become dissociated and shifted posteriorly. After birth the greater sphenoid wings and petrosal pyramids change again jointly
and with respect to midline cranial base elements. This sequential pattern of integration and modularization and re-integration
describes human basicranial ontogeny in a way that is potentially important for the understanding of evolutionary change.
Phylogenetic modifications of this pattern during morphogenesis, growth, and development may underlie the mosaic evolution
of the hominin basicranium. 相似文献
