Since the new Ethnicity Results appeared I have noticed Iberian Peninsula showing up a lot in my Dad's results. I mentioned this to him at lunch this week and we were all guessing where the Iberian Peninsula is located. My husband said immediately "Spain". Since we are looking for Native American I was a bit disappointed.
Last night, however, I decided to dig further into the Ethnicity Results. Imagine my surprise when I saw under "Other regions commonly seen in people native to Native American - Iberian Peninsula - 8%".
Ancestry goes on state "For those that do share some DNA with neighboring regions, about 8% of people native to this region also have at least some DNA similar to either the people from the Iberian Peninsula region-which was likely introduced by the Spanish and Portuguese explorers".
Note: The above quote was transcribed exactly as written in the ancestry ethnicity estimate. However, perhaps the "either" should have been left out (?).
At any rate, I was happy I looked deeper into the explanations by clicking on "Native American" under the Region Approximate Amount on the left-hand side of the page, or I would have missed this.
Hope this helps someone else. :)
