Geneticists have identified a major lineage of Y chromosomes in populations of northern China that they believe may mark the bearers as descendants of one of the Manchu conquerors who founded the Qing dynasty and ruled China from 1644 to 1911.
Because the founder of the lineage lived some 500 years ago, according to calculations based on the rate of genetic change, he may have been Giocangga, who died in 1582, the grandfather of the Manchu leader Nurhaci. At least 1.6 million men now carry this Manchu Y chromosome, says Chris Tyler-Smith, the leader of a team of English and Chinese geneticists.
