Nineteenth-century mulattos were taller than their darker-colored African-American counterparts. However, traditional explanations that attribute the mulatto stature advantage to only socioeconomic factors are yet to tie taller mulatto statures to observable phenomenon. Vitamin D production may also explain part of the nineteenth-century mulatto–black stature differential. Mulattos were taller than darker-pigmented blacks across the stature distribution, and higher melanin concentrations in darker black stratum corneums reduced the amount of vitamin D synthesized. The interaction with sunlight in darker-complexioned blacks was associated with larger stature returns for darker-complexioned blacks than their mulatto counterparts.
