How 'complex' or composite morphological structures like the mammalian craniomandibular region arise during development and how they are altered during evolution are two major unresolved questions in biology. Herein, we have described a model for the development and evolution of complex morphological structures. The model assumes that natural selection acts upon an array of phenotypes generated by variation in a variety of underlying genetic and epigenetic controlling factors. Selection refines… 
Development of the mouse mandible: a model system for complex morphological structures
TLDR
A key property of the anatomical, developmental, and functional complexity of the mouse mandible, like other morphological structures, is that it is shaped by various interactions and feedbacks among the processes involved, which leads to integration and possible modular organization of its component parts.
Developmental integration in a complex morphological structure: how distinct are the modules in the mouse mandible?
TLDR
Comparison of all alternative partitions of the landmarks into two contiguous subsets confirmed the hypothesis for the location of the boundary between modules but also underscored that the separation between them is not complete, indicating that developmental processes contribute differentially to variation at different levels.
Epigenetic Interactions and the Structure of Phenotypic Variation in the Cranium
TLDR
The results highlight regular and predictable patterns of covariation among regions of the skull that presumably reflect the epigenetic influences of the genetic perturbations in the sample, which may underlie larger scale evolutionary patterns in mammalian craniofacial form.
Epigenetic interactions and the structure of phenotypic variation in the cranium
TLDR
The results highlight regular and predictable patterns of covariation among regions of the skull that presumably reflect the epigenetic influences of the genetic perturbations in the sample, which may underlie larger scale evolutionary patterns in mammalian craniofacial form.
Developmental quantitative genetic models of evolutionary change.
TLDR
The algebraic equivalency of the Cowley and Atchley epigenetic model and Wagner's developmental mapping model is demonstrated, and a new multivariate model for continuous growth trajectories is proposed.
Evolution of ontogeny: linking epigenetic remodeling and genetic adaptation in skeletal structures.
TLDR
It is suggested that heterochronic shifts in ossification can not only buffer development under fluctuating environments while maintaining epigenetic sensitivity critical for normal skeletal formation, but also enable epigenetically induced gene expression to generate specialized morphological adaptations.
ADAPTIVE RADIATIONS, ECOLOGICAL SPECIALIZATION, AND THE EVOLUTIONARY INTEGRATION OF COMPLEX MORPHOLOGICAL STRUCTURES
TLDR
Results show that evolutionary integration patterns are largely a result of independent selection on specific components regardless of developmental modules, as well as ecological versus developmental factors underlying patterns of within‐species and evolutionary integration in the mandible of phyllostomid bats.
Statistical analysis of mandible form in the mouse
TLDR
This work uses multivariate statistical analyses on 14 morphological traits and body weight over 9 successive weeks for 6 inbred strains of 221 mice to describe multidimensional morphological variation in the mandible and to test several hypotheses.
Modularity in the skull and cranial vasculature of laboratory mice: implications for the evolution of complex phenotypes
TLDR
The results suggest that epigenetic interactions or genetic influences on regional development are more important determinants of covariation structure than the factors that produce covariation within individual tissues or organ systems.

TLDR
A model is presented which permits integration of developmental information into genetic discussions about evolutionary change in morphology and particular attention is given to the developmental origin of pleiotropic effects, developmental constraints, heterochrony, and the growth and morphogenesis of complex morphologies.

TLDR
It is concluded that morphogenesis is simply development or change of shape and distinguish morphogenesis both from differentiation and from growth, although predominant growth along one axis can alter shape.
Development and Quantitative Genetics of Correlation Structure Among Body Parts of Drosophila melanogaster
TLDR
The relationships between developmental components and correlation structure are explored for 17 head and thorax traits of Drosophila melanogaster, reflecting the similarity of cell doubling times of the various imaginal discs and the overlapping times of their growth during the larval instars.
A new approach to the generation of pattern and form in embryology.
TLDR
From the homogeneous mass of dividing cells in the very early stge of development, emerge the vast range of pattern and structure observed in animals, including butterfly wings, which exhibit spectacular colours and patterns and many animals develop dramatic coat markings.
Genetic analysis of size-scaling patterns in the mouse mandible.
TLDR
The relationship between multidimensional form of the adult mouse mandible and body size and the origin and ontogeny of phenotypic correlations are described in terms of genetic and environmental covariance patterns between adult skeletal morphology and growth in body weight.

The connective tissues of the craniofacial region can neither develop nor be maintained independently of their local environment. I have stressed such epigenetic control in the present brief review

TLDR
The interplay between genetic and epigenetic factors in morphogenesis and growth of craniofacial connective tissues is discussed and epigenetically initiated differentiation of secondary cartilage is shown to be epigenetic initiated by the mechanical environment created by muscle action.

TLDR
The proposed model provides a basis for developmental phenomena, such as pattern formation, morphogenesis, and regeneration, and it makes testable predictions at the molecular level.

TLDR
A model plan for the organization of gene activation during morphogenesis is described and it is proposed that genes of this sort bring about the changes seen in organ shape during evolution.
