“…a feature passively formed by functional surrounding structures, but its evolutionary retention and inheritance in a given lineage should confer some evolutionary advantages that conquer some known disadvantages this feature has, e.g. risk of sinus inflammation, polypoids, and aplasia and hypoplasia, which produce malformation in the cheek surface and orbital floor (Dumonceaux et al, 1997;Koppe et al, 2006;Zimmermann et al, 2011;. The advantages of such a spandrel-like feature are probably varied for different clades.…”

The nasal passages mainly adjust the temperature and humidity of inhaled air to reach the alveolar condition required in the lungs. By contrast to most other non-human primates, macaque monkeys are distributed widely among tropical, temperate and subarctic regions, and thus some species need to condition the inhaled air in cool and dry ambient atmospheric areas. The internal nasal anatomy is believed to have undergone adaptive modifications to improve the airconditioning performance. Furthermore, the maxillary sinus (MS), an accessory hollow communicating with the nasal cavity, is found in macaques, whereas it is absent in most other extant Old World monkeys, including savanna monkeys. In this study, we used computational fluid dynamics simulations to simulate the airflow and heat and water exchange over the mucosal surface in the nasal passage. Using the topology models of the nasal cavity with and without the MS, we demonstrated that the MS makes little contribution to the airflow pattern and the air-conditioning performance within the nasal cavity in macaques. Instead, the inhaled air is conditioned well in the anterior portion of the nasal cavity before reaching the MS in both macaques and savanna monkeys. These findings suggest that the evolutionary modifications and coetaneous variations in the nasal anatomy are rather independent of transitions and variations in the climate and atmospheric environment found in the habitats of macaques.

“…Similarly, extant great apes (i.e., Gorilla, Pan, Pongo ) also exhibit large zygomaticomaxillary interfaces and maxillary sinuses that extend laterally well into, or beyond, the zygomatic process of the maxilla (Cave and Haines, ; Koppe and Nagai, ; Koppe and Ohkawa, ; Rae and Koppe, ; Zollikofer et al, ). In contrast, several species of gibbon possess relatively small zygomaticomaxillary regions, along with maxillary sinuses with more minimal lateral extension (Cave and Haines, ; Rossie, ; Koppe et al, ). This latter finding appears to further support Rossie's () assertion that spatial availability, especially in superior‐inferior dimensions, mediates maxillary sinus pneumatization during ontogeny (see also Smith et al, ) across a greater range of primate taxa.…”

Previous research has suggested that the maxillary sinuses may act as "zones of accommodation" for the nasal region, minimizing the impact of climatic-related changes in nasal cavity breadth on surrounding skeletal structures. However, a recent study among modern human crania has identified that, in addition to nasal cavity breadth, sinus morphology also tracks lateral facial form, especially anterior-posterior positioning of the zygomatics. Here, we expand upon this previous study to further investigate these covariation patterns by employing three samples with distinct combinations of nasal and zygomatic morphologies: Northern Asians (n = 28); sub-Saharan Africans (n = 30); and Europeans (n = 29). For each cranium, 30 landmarks were digitized from CT-rendered models and subsequently assigned to either a midfacial or maxillary sinus "block." Two block partial least squares (2B-PLS) analyses indicate that sinus morphology primarily reflects superior-inferior dimensions of the midface, rather than either nasal cavity breadth or zygomatic position. Specifically, individuals with relatively tall midfacial skeletons exhibit more inferiorly and laterally expanded sinuses compared to those with shorter midfaces. Further, separate across-group and within-group 2B-PLS analyses indicate that regional differences between samples primarily build upon a common pattern of midfacial and sinus covariation already present within each regional group. Allometry, while present, only explains a small portion of the midface-sinus covariation pattern. We conclude that previous findings of larger maxillary sinuses among cold-adapted individuals are not predominantly due to possession of relatively narrow nasal cavities, but to greater maxillary and zygomatic heights. Implications for sinus function and midfacial ontogeny are discussed. Anat Rec, 300:209-225, 2017. © 2016 Wiley Periodicals, Inc.

“…This is not attributable to asymmetry in the frontal bone itself, as the frontals in these individuals seem to be symmetrical in cross section. Neither can it be attributed to pathology such as atelectasis, as no abnormal bone morphology is visible in the CT scans (Koppe et al. , 2006).…”

Evolution and functional morphology of the frontal sinuses in Bovidae (Mammalia: Artiodactyla), and implications for the evolution of cranial pneumaticity

The function and evolution of paranasal pneumaticity remains elusive, in part because of limited sampling and description. Here, the frontal sinuses from 62 species of bovids were investigated using X-ray computed tomography. This survey revealed hitherto undescribed diversity in the morphology of this sinus, and suggests that it was probably present in the common ancestor of Bovidae. Among extant bovids, the frontal sinuses were lost or reduced to recesses at least six different times. Quantitative analyses, when accounting for phylogeny using phylogenetically independent contrasts, did not find any link between the size or complexity of the frontal sinus and head-to-head ramming behaviour. Other analyses indicated that frontal sinus size was correlated most closely with the size of the frontal bone itself, rather than with the overall skull size or horn size. These results may be partially consistent with the hypothesis of sinuses being the result of 'opportunistic pneumatization', in which sinus size depends on the quantity of bone available for pneumatization as well as the mechanical demands placed on the skull. Additional evidence also indicates a strong phylogenetic correlation with sinus morphology, particularly with regard to the presence of paranasal diverticula, as well as the ability of sinuses to cross sutural boundaries.
