Beautiful Blonde Hair Dark Skin
Melanesia, Naturally Blonde
To some, light colored hair and dark skin tones are manipulated and chemically processed to achieve a style, but for the Melanesian people of Solomon Islands, blonde hair with dark skin is naturally inherited. This trait was so intriguing to many, that a study was conducted by a geneticist, Sean Myles, and his colleagues to find out more about this combination.
With an exception of the Melanesians, blonde hair is only found among people of European ancestry. Although the Melanesians are typically African physically they are believed to be closely related to the Aborigine family, anthropologists say that these two groups of people most likely separated some 10,000 years ago. Scientists claim that the blond hair in Melanesian people is caused by the inherited TYRP1 gene pigmentation. The TYR family of genes is also responsible for albinism. The Aborigines live in Australia and they are believed to be the indigenous people of the smallest continent in the world. Both the Aborigines and Melanesians are closely related to the early man.
According to research by various anthropologists the Melanesians, Papuan people and Australian Aborigines are the only modern humans whose pre-historic ancestors interbred with the ancient human speciesDenisova Hominin and they probably share almost 6% of their genes. They have also described Melanesians as a distinct racial group related to the Australian and Neptunian races.
Before the study, there were theories of European decedents and as stated by the an article by Erin Loury, “The Origin of Blond Afros in Melanesia”:
Hypotheses about the origins of this golden hair have included bleaching by sun and saltwater, a diet rich in fish, and the genetic legacy of Europeans or Americans.
However, the study presented Myles with interesting data. His team gathered 1209 Solomon Islanders and collected saliva and hair samples in search of an genetic relation to the trait. Further more:
They compared the entire genetic makeup of 43 blond and 42 dark-haired islanders. The two groups, they found, had different versions of a crucial gene, one that coded for a protein involved in pigmentation. Switching one “letter” of genetic code-replacing a “C” with a “T”-meant the difference between dark hair and blond hair. A similar mutation creates blond mice by reducing the melanin content in their fur.
In conclusion, blonde hair and dark skin is not as unnatural as some may think. Even scientist are taken back by this new found data: Read More: http://news.sciencemag.org/2012/05/origin-blond-afros-melanesia
