Don't sweat it: Ambient temperature does not affect social behavior and perception
2023, Journal of Economic PsychologyThe relative limb size of Homo naledi
2022, Journal of Human EvolutionCitation Excerpt :Observational and experimental research from extant nonhuman primates and modern humans can be applied to the study of early hominin variation and adaptation in body form. Limb proportions—including limb length, joint size, and limb robusticity—can provide information about arboreal behavioral activity (Stern and Susman, 1983; Susman et al., 1984), bipedal efficiency (Steudel-Numbers and Tilkens, 2004; Steudel-Numbers et al., 2007; Hora et al., 2014), thermoregulation (Wheeler, 1984; Ruff, 1991, 1993, 1994; Tilkens et al., 2007; Holliday and Hilton, 2010; Wall-Scheffler, 2014), and phylogenetic relationships (Holliday, 1997, 1999, 2012; McHenry and Berger, 1998a,b; Richmond et al., 2002; Green et al., 2007; Prabhat et al., 2021). Selection pressures acting on limb proportions played an important role in the mosaic transition from Australopithecus to Homo.
Dehydration and persistence hunting in Homo erectus
2020, Journal of Human EvolutionComparative evidence for the independent evolution of hair and sweat gland traits in primates
2018, Journal of Human EvolutionCitation Excerpt :Thermoregulatory sweating occurs in great apes and Old World monkeys (Johnson and Elizondo, 1974, 1979; Hiley, 1976; Whitford, 1976; Elizondo, 1977; Kolka and Elizondo, 1983), however, humans are exceptional among catarrhines in their dramatically enhanced sweating capabilities, which are exclusively dependent on the activity of eccrine glands (Folk, 1974; Hiley, 1976; Folk and Semken, 1991). Because a loss of fur cover leads to increased rates of convection and evaporation (Hardy, 1953; Dale et al., 1967; Wheeler, 1991), it has been proposed that the apparent nakedness of human skin enhances the effectiveness of eccrine sweating as a cooling mechanism (Carrier et al., 1984; Wheeler, 1984, 1991; Lieberman, 2015). However, the developmental origins of this striking appearance are unclear.
The costs of living at the edge: Seasonal stress in wild savanna-dwelling chimpanzees
2018, Journal of Human EvolutionCitation Excerpt :More broadly, our research provides insights into how early hominins, particularly those that had not yet undergone significant hair-loss, might have coped physiologically with thermoregulatory challenges of more open savanna or savanna-woodland environments. It likewise lends support to the assumption that thermoregulatory challenges likely posed a significant factor in hominin evolution (Wheeler, 1984, 1991, 1992b; Ruxton and Wilkinson, 2011a,b), and suggests that these challenges may have overshadowed the challenges of maintaining adequate energetic balance in this type of environment (Speakman and Król, 2010). Therefore, it lends support to the notion that mechanisms allowing individuals to cope with thermoregulatory pressures conferred an evolutionary advantage during the expansion of hominins from wetter, more forested habitats to drier savanna environments.
