The Evolution of Skin Color Penn State anthropologist Nina Jablonski is reimagining how we look at skin color. Universal We inherit our skin color from our ancestors, and so it is obviously a trait that is tied to our biology and genetics. But what is it that brought about such a diversity of human skin colors?

Human Skin Colour Distribution for Native Populations prior to 1940
Map of human skin color distribution in the world for native populations in 1940. It is easy to see why dark skin is an advantage in the tropics as a partial defense against skin cancer. It is much less easy to see why a white skin is an advantage in colder climates. Researchers have suggested two reasons, and both probably play a part. The.

OVERVIEW In The Biology of Skin Color, Penn State University anthropologist Dr. Nina Jablonski walks us through the evidence that the different shades of human skin color are evolutionary adaptations to the varying intensity of ultraviolet (UV) radiation in different parts of the world.

For example, native Canadian are darker skinned than what the map says, and the Maori are on average not 'white' as the map would lead one to believe. Native North-East Indians are fairer skinned than depicted. I did some more checking. The map from the Journal of Physical Anthropology, a 2004 issue.

Measures of skin reflectance, a way to quantify skin color by measuring the amount of light it reflects, in people around the world support this idea. While UV rays can cause skin cancer, because skin cancer usually affects people after they have had children, it likely had little effect on the evolution of skin color because evolution favors.

The skin color of individuals with light skin is specified mainly through the bluish-white connective tissue under the skin surface and by the hemoglobin leaking in the veins of the skin. There is a direct interrelationship between the geographic distribution of ultraviolet radiation and the dispersal of indigenous skin pigmentation worldwide.

The researchers found four key areas of the genome where variation closely correlated with skin color differences. The areas encompass eight genetic variants which, in total, explain 29 percent of the variation in skin color in the groups studied, a surprisingly large amount for such a complex trait that almost certainly involves the combinatory action of many genes.
