Since Europeans carry sub clades, donwstreams. (only) Adaptations to Climate-Mediated Selective Pressures in Humans Angela M. Hancock et al. Since human populations occupy a wide variety of environments with respect to climate, selective pressures are expected to vary greatly across geographic regions. Adaptations to spatially varying selective pressures are evident in the geographic distributions of many traits. For example, significant correlations exist between body mass and temperature [13]–[14], consistent with Bergmann's and Allen's Rules. Furthermore, there is evidence that human metabolism has been shaped by adaptations to cold stress from studies of arctic populations, which exhibit elevated basal metabolic rates compared to non-indigenous populations [15]. [b]Like body mass, variation in skin pigmentation is strongly correlated with climate and geography, i.e. distance from the equator and solar radiation [16]–[17]. Lighter pigmentation is likely to be adaptive in high latitudes, in part, because UV light is needed to penetrate the skin to produce vitamin D [16]–[19], which is necessary for calcium absorption and bone growth.[/b] [IMG]http://www.plosgenetics.org/article/fetchObject.action?uri=info%3Adoi%2F10.1371%2Fjournal.pgen.1001375.g001&representation=PNG_M[/IMG] (A) Maps show the distributions of summer and winter climate variables: maximum summer temperature, minimum winter temperature and solar radiation, precipitation rate and relative humidity in the summer and winter. (B) A heatmap shows the absolute values of Spearman rank correlation coefficients between pairs of climate variables.
