A team of geneticists led by Sarah Tishkoff, a Penn Integrates Knowledge Professor, has shown that there is a huge amount of variation of skin color within Africa, ranging from skin as light as some Asians to the darkest skin on a global level.

2024年8月26日 · South Sudan: South Sudanese people often have some of the darkest skin tones in Africa. This is attributed to the region’s high levels of melanin, which provides protection against intense...

2017年10月12日 · But different groups of people in Africa have almost every skin color on the planet, from deepest black in the Dinka of South Sudan to beige in the San of South Africa. Now, researchers have discovered a handful of new gene variants responsible for this palette of tones.

2017年10月13日 · But different groups of people in Africa have almost every skin color on the planet, from deepest black in the Dinka of South Sudan to beige in the San of South Africa. Now, researchers have discovered a handful of new gene variants responsible for this palette of tones.

The scientists examined the genetic origins of skin color in Africans — who vary widely in shade from the dark skin of the Dinka people in South Sudan to the light-complexions of the San of South Africa.

Human skin color ranges from the darkest brown to the lightest hues. Differences in skin color among individuals is caused by variation in pigmentation, which is the result of genetics (inherited from one's biological parents), exposure to the sun, disorders, or some combination thereof.

2019年3月4日 · Many different completely natural African skin tones ranging from very dark to very light, from Dinka of South Sudan to San of South Africa respectively.

2022年9月30日 · Until recently many scientists were of the view that the dark skin color of Africans was a permanent characteristic in their genes; a feature meant to protect those in the African continent...

Recent genome-wide genetic studies of skin pigmentation in African populations have advanced our understanding of pigmentation biology and human evolutionary history. For example, novel roles in skin pigmentation for loci near MFSD12 and …

2017年10月25日 · Skin color is one of humankind’s most striking—and stunningly variable—traits. With a new study of diverse African groups, a team of geneticists led
