“…Indeed, Byard (1981, p. 132) noted that the fact that samples of different age composition have been compared has contributed to a ''confusing picture of sex differences in pigmentation'' (see also Kalla 1973Kalla , 1974. We acknowledge that we are relying on other authors' statements that their subjects are adults, and that our decision to exclude children and teenagers caused us to discard a good number of papers (e.g., Byard and Lees, 1982;Carbonnel and Olivier, 1966;Chamla and Demoulin, 1978;Clark et al, 1981;Conway and Baker, 1972; Greksa, 1998a,b;Harrison and Owen, 1964;Harrison and Salzano, 1966;Harrison et al, 1967;Harvey and Lord, 1978;Hulse, 1967Hulse, , 1973Kalla, 1973;Kalla and Tiwari, 1970;Lasker, 1954;Ojikutu, 1974;Omoto, 1968;Park and Lee, 2005;Relethford et al, 1985;Rebato et al, 1993;Smith and Mitchell, 1973;Sunderland and Coope, 1973;Sunderland and Woolley, 1982;Walsh, 1963; Wasserman and Heyl, 1968;Weiner et al, 1963). Our sample is smaller than that used by Relethford (1997Relethford ( , 2000 because he used male-only data sets, and we excluded papers which only reported data on one gender or which pooled male and female data (Bü chi, 1957(Bü chi, /1958Caro, 1980;Das and Mukherjee, 1963;Ducros et al, 1975;Eriksson et al, 1980;Garrard et al, 1967;Harrison and Owen, 1964;…”

Applied to skin color, the sexual selection hypothesis proposes that male preference for light-skinned females explains the presence of light skin in areas of low solar radiation. According to this proposal, in areas of high solar radiation, natural selection for dark skin overrides the universal preference of males for light females. But in areas in which natural selection ceases to act, sexual selection becomes more important, and causes human populations to become light-skinned, and females to be lighter than males. The sexual selection hypothesis proposes that human sexual dimorphism of skin color should be positively correlated with distance from the equator. We tested the prediction that sexual dimorphism should increase with increasing latitude, using adult-only data sets derived from measurements with standard reflectance spectrophotometric devices. Our analysis failed to support the prediction of a positive correlation between increasing distance from the equator and increased sexual dimorphism. We found no evidence in support of the sexual selection hypothesis.
