Skin and bone are not a basis for rank. Office life lowers sun exposure globally, decoupling deficiency from ancestry alone.
Because curiosity about bodies is valid — and unanswered curiosity is where race myths recruit. Only to explain mechanisms or public health. Averages never become league tables of worth. No. Clinical decisions need clinicians, not atlas pages. By preferring review-level consensus and labeling open debates.
A gradual change in trait frequency across geography, rather than a sharp racial border. Yes — dairying, malaria and altitude are classic feedback loops. See related diversity topics and the atlas page on genetic-distance myths. Vitamin D begins as a skin precursor converted by UVB light, then activated in liver and kidney to a hormone regulating calcium and immune signaling.
Darker pigmentation filters UV — an evolutionary trade-off in high-UV places — while low-UV latitudes, clothing and indoor work shift needs. UVB intensity depends on latitude, season, time of day and air pollution. Melanin reduces synthesis rate but does not eliminate it — dose and duration matter.
Fold the league table. Keep , “UV radiation and vitamin D synthesis reviews,” and 7 for Vitamin D.7
