The genetic root of the diversity of skin colors
In a striking study by scientists, human skin has been studied on genetic structures underlying color differences. Scientists who research have found that in Europe the genes are derived from Africa. Over the years people have divided their species into groups according to their color. The color tone of one person's face affected other people's thoughts about this person. He decided where he would live, how much money he could make, and most importantly, whether he could have a political power to represent him. Throughout history, racial divisions have emerged from the color of the skin resulting from war and violence.
Scientists tell us that racial discrimination for years has been a concept invented by people on their heads and that people with different color tones actually have no real differences in their genetic makeup. The majority of mankind has maintained the belief that the people on the skin can not be destroyed.
However, this groundbreaking study published by international researchers in the Science magazine may put an end to the perception that the concept of human race in the head is a biological concept, and even this perception can be edited. Scientists conducting the research have rejected the idea that skin color is a factor in racial discrimination, revealing that neither the European nor the European color of light skin is related to the external appearance of the skin color.
The people of San, who live in South Africa, have a clearer skin color than most people in Africa.
Scientists have studied the genetic origins of the skin colors of African Americans from the skin color of San Africans, who have a much brighter skin color than South African Dinka people in South Africa. In addition to the research in the Science magazine, another news report showed how the light measuring device's research team measured how much more than 2000 people reacted to their skin. In addition to the measurements of researchers on the agenda, it was also stated that the subjects had collected blood samples for genetic investigations.
This research on African humans has great implications, because a myriad of previous researches on Europeans, and a genetically structured genetic makeup on Europeans, have led to inadequate and misunderstood race and genetic links.
Sarah Tishkoff, a writer and professor of genetics and biology at the University of Pennsylvania, also wrote a letter about the majority of scientists involved in genetic research, especially the European population. researchers have fallen. "This misunderstanding is causing us to be unaware of the genetic factors that determine our personal qualities, such as our skin color, and give us an idea of how much health risk people have," Sarah says. In particular, researches exclusively on Europeans often miss most of the variables associated with our skin color.
Senior research scientist Alessia Ranciaro measures how often a person in the Nilo-Saharan ethnic group, which usually has a very dark skin color, reacts to the sun's skin.
Tishkoff says, "While it is not known that variables related to light and dark-skinned before our research are common and very old in Africa." "Our research shows that dark and light skin develops in all people," says Sarah. (Before we came to investigate, we searched why Europeans had light skin color). Sarah emphasizes that recent research has changed the universal history of change in skin color.
Scientists have identified eight genetic variations that affect skin pigmentation in four regions of human skin. More than 4 million single nucleotide polymorphisms have been discovered using approximately 1,600 genetic information. As a result of these investigations, it has been determined that gene variations in Africa, which cause Europeans to have a clear skin color, have emerged in Africa.
