| This analysis suggested that the African population is close to equilibrium between mutational forces and genetic drift. |
| This sampling error causes random fluctuations in allele frequencies called genetic drift. |
| The first alternative is that the long basal branches are simply the chance result of genetic drift in a large, panmictic ancestral population. |
| This is different than the traditional effective sizes, which are descriptions of the equilibrium behavior of genetic drift in the population. |
| This positive feedback loop implies an evolutionary pattern of divergent genetic drift to high or low GC contents. |
| Phenotypic variation among primates results primarily from Darwinian selection, mate choice, and genetic drift. |
