However today the science went further to identify the remaining less-than 1%, to explain such differences as a lighter skin of Europeans, feature of Asians to sweat less, and the resistance of Africans to certain diseases.
The genetic ancestry has become of great interest for everyday citizens. Now there are available the ancestry tests, which will tell you how much of your genes come from Europe, Asia, Africa or America. The genetic differences are used during creating medicines, such as a heart-disease drug BiDil effective in Afro-Americans, and prenatal tests for Jewish for identification of prenatal genetic disorders which are rarely found in other ethnic and racial groups.
However on the other hand many fear those problems which will be created by manipulating the fact that race is more than just the color of your skin. This can once again undermine the basis of democracy- fundamental equality of all human.
The genetics assert that the tiny differences, which arose in the human genome, during the migration of our ancestors to the various parts of the world, are crucial for creation of the medicines, based on the genetic peculiarities of a given race. However the scientists fear to talk openly about the racial distinctions they observe, in order to avoid fuelling a new sort of racial segregation between people.
“There are clear differences between people of different continental ancestries,” said Marcus W. Feldman, a professor of biological sciences at Stanford University. “It’s not there yet for things like I.Q., but I can see it coming. And it has the potential to spark a new era of racism if we do not start explaining it better.”
Although according to the experts, the real distinction between people is created rather by their environment than their genes, the genetics are still viewed as more authoritative evidence.
“I’ve spent the last 10 years of my life researching how much genetic variability there is between populations,” said Dr. David Altshuler, director of the Program in Medical and Population Genetics at the Broad Institute in Cambridge, Mass. “But living in America, it is so clear that the economic and social and educational differences have so much more influence than genes. People just somehow fixate on genetics, even if the influence is very small.”
Although the scientists think time is not yet ripe to speak about the social implications of their researches, they still do not recommend to neglect the genetic evidence. Acccording to Dr Perry Clark, writing in the New York Times Blog: “To say that such differences aren’t real,” Dr. Clark later said in an interview, “is to stick your head in the sand and go blah blah blah blah blah until the band marches by... When was the last time a nonblack sprinter won the Olympic 100 meters?”- He asked.
