“…Regardless of the underlying factors driving internal nasal fossa morphology, the fact that our study did not find other morphofunctional units of the nasal complex to be significantly associated with climate stands in contrast to many previous studies (Carey & Steegmann, 1981;Cottle, 1955;Crognier, 1981aCrognier, , 1981bDavies, 1934;Hiernaux & Froment, 1976;Thomson & Buxton, 1923;Weiner, 1954;Woo & Morant, 1934). In particular, a large number of anthropological studies have purported an association between nasal aperture morphology and various climatic variables (Crognier, 1981a(Crognier, , 1981bDavies, 1934;Hiernaux & Froment, 1976;Thomson & Buxton, 1923;Weiner, 1954).…”

“…To a large degree, this can be attributed to the fact that the majority of studies related to climatic adaption in human nasal morphology have focused on a single morphofunctional unit (Carey & Steegmann, 1981;Cottle, 1955;Crognier, 1981aCrognier, , 1981bDavies, 1932;Franciscus & Long, 1991;Hiernaux & Froment, 1976;Schlager & R€ udell, 2015;Thomson, 1913;Thomson & Buxton, 1923;Weiner, 1954;Woo & Morant, 1934;Yokley, 2009), preventing direct comparisons across different components of the nasorespiratory tract.

“…While these previously discussed studies have provided important insights into ecogeographic variation in human internal nasal fossa morphology, it still remains unclear whether the internal nasal fossa actually exhibits stronger associations with climate compared to the external pyramid, nasal aperture or nasopharynx. To a large degree, this can be attributed to the fact that the majority of studies related to climatic adaption in human nasal morphology have focused on a single morphofunctional unit (Carey & Steegmann, 1981;Cottle, 1955;Crognier, 1981aCrognier, , 1981bDavies, 1932;Franciscus & Long, 1991;Hiernaux & Froment, 1976;Schlager & R€ udell, 2015;Thomson, 1913;Thomson & Buxton, 1923;Weiner, 1954;Woo & Morant, 1934;Yokley, 2009), preventing direct comparisons across different components of the nasorespiratory tract. Further, the few studies (Charles, 1930;Evteev et al, 2014;Fukase et al, 2016;Franciscus, 1995;Noback et al, 2011) incorporating multiple morphofunctional units have either assessed climatic associations across all the units collectively, preventing assessment of each unit's independent association with climate (Noback et al, 2011), or have employed samples which do not encompass the full range of climates encountered by modern humans (Charles, 1930;Evteev et al, 2014;Franciscus, 1995;Fukase et al, 2016).…”

Our study indicates that the internal nasal fossa exhibits a stronger association with climate compared to other aspects of the human nose. Further, our study supports suggestions that regional variation in internal nasal fossa morphology reflects demands for heat and moisture exchange via adjustment of internal nasal airway dimensions. Our study thus provides empirical support for theoretical assertions related to nasorespiratory function, with important implications for understanding human nasal evolution.

“…Population variation in internal and external nasal morphology, including nasal projection and nasal bridge elevation, has been explained largely within the context of climatic adaptation (Thomson & Buxton, 1923; Davies, 1932; Weiner, 1954; Wolpoff, 1968; Hiernaux & Froment, 1976; Carey & Steegmann, 1981; Crognier, 1981a,b; Franciscus & Long, 1991; Franciscus, 1995; Roseman, 2004; Yokley, 2006, 2009; Holton & Franciscus, 2008; Hubbe et al. 2009; Holton et al 2011b).…”

Nasal septal and craniofacial form in European‐ and African‐derived populations

2012

As a component of the chondrocranium, the nasal septum influences the anteroposterior dimensions of the facial skeleton. The role of the septum as a facial growth center, however, has been studied primarily in longsnouted mammals, and its precise influence on human facial growth is not as well understood. Whereas the nasal septum may be important in the anterior growth of the human facial skeleton early in ontogeny, the high incidence of nasal septal deviation in humans suggests the septum's influence on human facial length is limited to the early phases of facial growth. Nevertheless, the nasal septum follows a growth trajectory similar to the facial skeleton and, as such, its prolonged period of growth may influence other aspects of facial development. Using computed tomography scans of living human subjects (n = 70), the goal of the present study is to assess the morphological relationship between the nasal septum and facial skeleton in European-and African-derived populations, which have been shown to exhibit early developmental differences in the nasal septal-premaxillary complex. First we assessed whether there is population variation in the size of the nasal septum in European-and African-derived samples. This included an evaluation of septal deviation and the spatial constraints that influence variation in this condition. Next, we assessed the relationship between nasal septal size and craniofacial shape using multivariate regression techniques. Our results indicate that there is significant population variation in septal size and magnitude of septal deviation, both of which are greater in the European-derived sample. While septal deviation suggests a disjunction between the nasal septum and other components of the facial skeleton, we nevertheless found a significant relationship between the size of the nasal septum and craniofacial shape, which appears to largely be a response to the need to accommodate variation in nasal septal size.

“…The question is whether skull measurements are heritable (Sjovold, 1984), or whether they can characterise the structure of human populations (Sokal et al, 1987a). An answer to this question is given by a number of studies, which indicate that many of the cranial measurements have heritable components (Sjovold 1984;Crognier E. 1981;Keita, 1988). Based on these considerations the study of prehistoric populations provides us with information about differences in the morphometric patterns, when we compare populations from different time periods.…”
