The protruding chin is an attribute that defines modern Homo sapiens to the exclusion of all other primates, including fossil hominids. The functional significance of the chin has been contemplated for most of the 20th century, but as yet no compelling functional argument for its evolution has withstood careful scrutiny. Consequently, the human chin is often cited as an example of a nonadaptive trait. Past attempts to explain the chin in a functional or mechanical context have failed, largely…

The enduring puzzle of the human chin
A century's worth of chin hypotheses are reviewed and future research avenues that may provide greater insight into this human peculiarity are discussed.
The Fetal Origin of the Human Chin
A developmental sequence leading to a chin prominence during early fetal development is discovered that is very similar to that which was observed in postnatal modern humans and in chimpanzee fetuses and the evidence that the inverted-T relief is developmentally integrated with the chin prominence is provided.
The Human Mandible and the Origins of Speech
The potential covariation between the expression of the chin and bone hypertrophy is explored in an attempt to clarify their respective biomechanical roles.
Sexual dimorphism in chin shape: implications for adaptive hypotheses.
These findings provide the first quantitative, morphologically based evidence in support of adaptive hypotheses that predict dimorphism in chin shape, including the sexual selection hypothesis.
Why do humans have chins? Testing the mechanical significance of modern human symphyseal morphology with finite element analysis.
The results of this study corroborate prior hypotheses about the mechanical effects of the human chin and vertical symphysis orientation and support the idea that the relative importance of wishboning and vertical bending in the coronal plane might have played a role in the evolution of modern human symphyseal morphology.
The Masticatory Apparatus of Humans (Homo sapiens): Evolution and Comparative Functional Morphology
Any performance deficits in the human masticatory apparatus are primarily related to gracilization, suggesting the evolution of humans has not unraveled the basic functional relationships within the masticatories apparatus that characterize most primates.
The ontogeny of the chin: an analysis of allometric and biomechanical scaling
It is indicated that ontogenetic increases in chin projection do not provide greater bending resistance to the mandibular symphysis, and a complex interaction between symphyseal ontogeny and bending resistance is suggested.
Growth-related changes in prehistoric Jomon and modern Japanese mandibles with emphasis on cortical bone distribution.
The findings suggest that the "robust" characteristics of the Jomon mandible are initially manifested early in development, and that the effect of mechanical stimulus to bone mass formation in the human symphysis is largely confined to a regulatory role during growth modeling.


Evolution of the Chin
The evidence is suggested to suggest some of the evidence which would seem to indicate that Dr. Robinson's ideas need rather careful review.
Ontogeny of the early hominid face
The basicranium of Plio-Pleistocene hominids as an indicator of their upper respiratory systems.
Craniometric analysis of the basicrania of the Plio-Pleistocene hominids showed that they had marked similarities to those of extant pongids, suggesting that the upper respiratory systems of these groups were also alike in appearance.
The development and structure of the chimpanzee mandible.
Although the pattern of distribution of cortical densities differed from that of surface remodeling, the information they give is complementary in analysing bone growth and areas where remodeling led to the greatest reorientation of bone tissue within the cortex showed the greatest disparity between the two patterns.
The functional significance of morphological variation of the human mandible and masticatory muscles.
In human populations there are clear-cut patterns of correlation between some facial skeletal traits, jaw joint morphology and strength and line of action of the jaw muscles and facial morphologies can be distinguished with marked differences in mechanical performance of their masticatory apparatus.
Comparative Functional Morphology of Maximum Mandibular Opening (Gape) in Primates
There is wide variation among primates in the size and shape of teeth, the size and position of masticatory muscles, and the morphology of the craniofacial skeleton. The functional significance of

Growth changes in the monkey and human facial skeleton are compared and contrasted, and the developmental and phylogenetic basis for the upright human face is discussed and evaluated.
Biomechanical Models and the Analysis of Form: A Study of the Mammalian Masticatory Apparatus
Direct, experimental study of jaw movements and muscle activities has revealed new data, highly relevant to the construction of realistic mechanical models and the explanation of aspects of the morphology of the chewing apparatus.

Stand against this Synthetic theory, and generally lacking both its brilliant advocacy and its present massive support, is a diverse group of theories which attribute a significant role to inadaptive or non-adaptive structures.
