Jy. Chu et al., GENETIC-RELATIONSHIP OF POPULATIONS IN CHINA, Proceedings of the National Academy of Sciences of the United Statesof America, 95(20), 1998, pp. 11763-11768
Despite the fact that the continuity of morphology of fossil specimens
of modern humans found in China has repeatedly challenged the Out-of-
Africa hypothesis, Chinese populations are underrepresented in genetic
studies. Genetic profiles of 28 populations sampled in China supporte
d the distinction between southern and northern populations, while the
latter are biphyletic. Linguistic boundaries are often transgressed a
cross language families studied, reflecting substantial gene flow betw
een populations, Nevertheless, genetic evidence does not support an in
dependent origin of Homo sapiens in China. The phylogeny also suggeste
d that it is more likely that ancestors of the populations currently r
esiding in East Asia entered from Southeast Asia.
