1. Glaciation may have caused its habitat loss, genetic isolation then local adaption. 2. We look at it as one of the ultimate genetic isolation mechanisms. 3. Also need to be concerned about genetic isolation of populations by dams. 4. Glaciation may have caused its habitat loss, genetic isolation then local adaptation. 5. They show subtle evidence of genetic isolation but less than Sardinians and French Basques. 6. He counted thirty-four local races in the world that had arisen from genetic isolation . 7. One reason that might not be thought of as a main reason is genetic isolation . 8. Genetic isolation is rarely complemented by morphological evolution.9. The geographic separation and subsequent genetic isolation of portions of an ancestral population can result in speciation. 10. The Simi's undeveloped native habitat provides routes that protect larger land wildlife of the Santa Monicas from genetic isolation .
