...people residing in Europe, Middle East, and South Asia (India) share common ancestral markers
dating 10 to 50,000 years ago. In testing various world populations, for example, South Asian Indians are
found to have a substantial, but lower, level of “European” markers while Middle Easterners exhibit a
higher level of “European” markers. In the DNA Origins test, the average South Asian Indian exhibits
58% European ancestry, while Middle Easterners have about 80-90% European ancestry. Additional
examples of test results from various world populations are provided in the chapter, “Average Results for
Various Populations.”
The Indigenous American founding population also calls for more explanation, because of this group’s
migration history.
Indigenous Americans came into the New World from Central Asia over many thousands of years in
three major migrational waves: The first started possibly as long as 30,000 years ago and brought in
the Amerind speakers. This is the largest group of Indigenous Americans in the Western Hemisphere,
and over the ages they have intermingled with other populations like the Spanish invaders and other
Indigenous Americans....
Because of the migration pattern of Indigenous Americans, many people of Italian, Greek or Turkish
heritage (and some Middle Easterners) may show “Indigenous American” ancestry—as much as ten
percent—because of migrations from Central Asia south and west into those regions. Turkey was the
passageway into Europe from Asia (the region occupied by Uzbekistan, Kazhakstan, Afghanistan,
Southwestern Siberia, etc.). Central Asians do show overlapping markers with Indigenous Americans who
migrated North and East to the Bering land bridge and into the New World.
Further, many people with European heritage should take into consideration the fact that the Roman
(Italian) armies conquered and occupied much of Europe—including England—for more than 1,000
years, resulting in an intermingling of the genetics markers from that source. (Ireland, which is an island,
was never occupied by the Romans, so many of the descendants of earlier “Erse” ancestors approach
100% in their European genetic portraits.) Thus, low levels of Indigenous American heritage could be
detected in Europeans whose ancestors may have never set foot in the New World....
These ranges show the other percentages this person could be, though any percentage is up to two times
less likely than the percentage indicated by the red bar. Though this person is most likely to be 45%
European, and 55% Indigenous American, they could also possibly be 35% European, 65% Indigenous
American—though it is two times less likely than the MLE value of 45% European, 55% Indigenous
American. You will notice that there are confidence bars for the East Asian (EA) and African (AF) groups
too. Thus, it is possible that this person is 44% European, 54% Indigenous American, 1% Sub-Saharan
African and 1% East Asian, though again, it is significantly less likely than the most likely estimate of 45%
European, 55% Indigenous American.
