Human skin and hair color are visible traits that can vary dramatically within and across
ethnic populations. The genetic makeup of these traits—including polymorphisms in the …

The primary biological role of human skin pigmentation is as a mediator of penetration of
ultraviolet radiation (UVR) into the deep layers of skin and the cutaneous circulation. Since …

Like many highly variable human traits, more than a dozen genes are known to contribute to
the full range of skin color. However, the historical bias in favor of genetic studies in …

Skin pigmentation is a complex, conspicuous, highly variable human trait that exhibits a
remarkable correlation with latitude. The evolutionary history and genetic basis of skin color …

Human biological variation has historically been studied through the lens of racialization.
Despite a general shift away from the use of overt racial terminologies, the underlying …

The evolution of light-skin pigmentation among Eurasians is considered as an adaptation to
the high-latitude environments. East Asians are ideal populations for studying skin color …

Objectives Skin pigmentation is both a highly variable and highly visible human phenotypic
trait. Investigations into the biology and origins of this variation have been the focus of …

Abstract Background The ITA° is the gold standard for skin tone classification. Different skin
tones are often associated with different skin characteristics and issues. Different skin types …

Sun safety research has mainly been conducted in the West, whereas little is known about
sun protection practices in India. Using a survey design with a representative sample, we …

Most hair follicles on the human body have evolved to be miniaturized, rendering us
practically 'naked'. Despite sparse body hair, we retain thick hair on our scalps that varies …
