DNA INFORMATION
Wallace's newest and most surprising discovery is a set of genetic markers found only in the Objiwa and other tribes living near the Great Lakes; the markers are not found in any other native Americans or in Asia.
"We just don't know how it got there," Wallace says, "but it is clearly related to the European population." The simple answer would be the DNA arrived with the European colonists, but the strain is different enough from the existing European lineage that it must have left the Old World long before Columbus. (US News and World Report, Jan 20, 2001 pp. 37-40)
Comment: Wallace measured "... long before Columbus." in milliniums, not cecnturies. The best estimate of the origin of the "genetic markers," to date, is 18,000 years before present. But the European "genetic markers" have not yet been found, for sure, in North America skeletons who died before 700 years ago. Thus, the "genetic markers" may be biological evidence of population(s) that originated in Europe but migrated to America in the last millinium.
