O. Semino et al., The genetic legacy of paleolithic Homo sapiens sapiens in extant Europeans: A Y chromosome perspective, SCIENCE, 290(5494), 2000, pp. 1155-1159
A genetic perspective of human history in Europe was derived from 22 binary
markers of the nonrecombining Y chromosome (NRY). Ten lineages account for
>95% of the 1007 European Y chromosomes studied. Geographic distribution a
nd age estimates of alleles are compatible with two Paleolithic and one Neo
lithic migratory episode that have contributed to the modern European gene
pool. A significant correlation between the NRY haplotype data and principa
l components based on 95 protein markers was observed, indicating the effec
tiveness of NRY binary polymorphisms in the characterization of human popul
ation composition and history.
