“…During the Pleistocene, the genus Homo experienced a significant reduction in body mass, with archaic Homo (e.g., H. neanderthalensis, H. heidelbergensis) generally characterized by greater body mass estimates compared to fossil and recent H. sapiens (Ruff et al, 1997(Ruff et al, , 2005Churchill et al, 2012;Froehle et al, 2013). While the causal mechanisms associated with this trend in size reduction are incompletely understood, researchers have repeatedly shown that as a result of body mass differences, the basal metabolic rate and DEE of archaic Homo would have exceeded those of early modern and recent H. sapiens (e.g., Sorensen and Leonard, 2001;Aiello and Wheeler, 2003;Churchill, 2006;Cartmill and Smith, 2009;Froehle and Churchill, 2009;Froehle et al, 2013). As a result, archaic Homo would have had substantially higher requisite oxygen demands when compared to modern H. sapiens.…”

“…Researchers have hypothesized that variation in nasal morphology, both in archaic Homo and in recent humans, is influenced by body mass and associated oxygen consumption demands required for tissue maintenance Froehle et al, 2013). The present study contributes to our understanding of this potential developmental and functional dynamic by assessing sexual dimorphism in nasal cavity size in a longitudinal recent human sample in order to (a) assess sexual dimorphism in the nasal cavity in recent humans and determine when during ontogeny male-female differences in nasal cavity size appear; and (b) determine if there are significant differences in nasal/body size scaling relationships in males and females during ontogeny.…”
