Abstract excerpt
mtDNA sequence variation was examined in 175 Caucasians from the United States and Canada by PCR amplification and high-resolution restriction-endonuclease analysis. The majority of the Caucasian mtDNAs were subsumed within four mtDNA lineages (haplogroups) defined by mutations that are rarely seen in Africans and Mongoloids. The sequence divergence of these haplogroups indicates that they arose early in...
