DNA data fuel new racism fears

first_imgThough few of the bits of human genetic code that vary between individuals have yet to be tied to physical or behavioral traits, scientists have found that roughly 10 percent of them are more common in certain continental groups, and can be used to distinguish people of different races. They say that studying the differences, which arose during the tens of thousands of years that human populations evolved on separate continents after their ancestors dispersed from humanity’s birthplace in East Africa, is crucial to mapping the genetic basis for disease. But many geneticists, wary of fueling discrimination and worried that speaking openly about race could endanger support for their research, are loath to discuss the social implications of their findings. Still, some acknowledge that as their data and methods are extended to nonmedical traits, the field has reached what one leading researcher recently called “a very delicate time and a dangerous time.” “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 IQ, 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.” Feldman said any finding on intelligence was likely to be exceedingly hard to pin down. But given that some may emerge, he said he wanted to create “ready response teams” of geneticists to put such socially fraught discoveries in perspective. The authority that DNA has earned through its use in freeing falsely convicted inmates, preventing disease and tracing family ties leads people to wrongly elevate genetics over other explanations for differences between groups. “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.”160Want local news?Sign up for the Localist and stay informed Something went wrong.

NEW YORK – When scientists first decoded the human genome in 2000, they were quick to portray it as proof of humankind’s remarkable similarity. The DNA of any two people, they emphasized, is at least 99 percent identical. But new research is exploring the remaining fraction to explain differences between people of different continental origins. Scientists, for instance, have recently identified small changes in DNA that account for the pale skin of Europeans, the tendency of Asians to sweat less and West Africans’ resistance to certain diseases. At the same time, genetic information is slipping out of the laboratory and into everyday life, carrying with it the inescapable message that people of different races have different DNA. Ancestry tests tell customers what percentage of their genes is from Asia, Europe, Africa and the Americas. The heart-disease drug BiDil is marketed exclusively to black people, who seem genetically predisposed to respond to it. Jews are offered prenatal tests for genetic disorders rarely found in other ethnic groups.

Yet some social critics fear they may also be giving long-discredited racial prejudices a new potency. The notion that race is more than skin-deep, they fear, could undermine principles of equal treatment and opportunity that rely on the presumption that we are all fundamentally equal. “We are living through an era of the ascendance of biology, and we have to be very careful,” said Henry Louis Gates Jr., director of the W.E.B. Du Bois Institute for African and African American Research at Harvard University. “We will all be walking a fine line between using biology and allowing it to be abused.” Certain superficial traits like skin pigmentation or disease predispositions have long been presumed to be genetic. Now, the ability to pinpoint their source in DNA is prompting the question on mainstream Internet discussion sites, in college classrooms and among the growing community of ancestry test-takers, of whether more profound differences may also be attributed to genetics. Nonscientists are already beginning to stitch together highly speculative conclusions about the historically charged subject of race and intelligence from the new biological data. Last month, a blogger in Manhattan described a recently published study that linked several snippets of DNA to high IQ. An online genetic database used by medical researchers, he told readers, showed that two of the snippets were found more often in Europeans and Asians than in Africans. No matter that the link between IQ and those particular bits of DNA was unconfirmed, or that other high-IQ snippets are more common in Africans, or that hundreds or thousands of others may also affect intelligence, or that their combined influence might be dwarfed by environmental factors. Just the existence of such genetic differences between races, proclaimed the author of the Half Sigma blog, a 40-year-old software developer, means “the egalitarian theory” that all races are equal “is proven false.” last_img read more
