Ontogenetic allometry in the thoracolumbar spine of mammal species with differing gait use.

abstract：:The generation of coordinated morphological change over time results from the interconnectedness of evolution and development. The modular architecture of development results in varying degrees of integration and independence among parts of the phenotype, and facilitates the production of phenotypic variation in compl...
