| Sumario: | A study was conducted to distinguish more effectively between an A.D. 1,000 Numic expansion into the Great Basin region of the U.S. versus population continuity. A novel computer simulation approach that incorporated microevolutionary factors likely to affect human population genetic variation was applied to compare pre-expansion genetic data from Stillwater Marsh in western Nevada with those of modern Northern Paiute speakers from the western Great Basin area. Findings revealed that under reasonable demographic conditions, the observed genetic differences between the study samples are consistent with population continuity if gene flow among prehistoric Great Basin local groups was less than 1 percent of local group size per generation. Findings also indicated that the observed degree of genetic differences between population samples may be attributable to relatively low gene flow levels and random genetic drift. |
