    3. Just be aware that the testing done by scientific studies like this are much more complex than those done by commercial organisations and they use carefully selected participants whose ancestors have not moved outside the areas being studied for generations. DNA inheritance is a lottery and you don't inherit DNA from all of your ancestors. Each one of us inherits half our DNA from our mother and half from our father. This is random so siblings haven't inherited the identical subset of their parents DNA unless they are identical twins. Over time the DNA from some of our ancestors will vanish competely. This exhibition at Oxford University's Museum of Natural History explains this: http://www.oum.ox.ac.uk/settlers/ As an example of how random the DNA distribution is after a few generations, I matched with two descendants of my great grandfather's sister who emigrated in the 1880s. They are first cousins but one is an "extremely high confidence 4-6 generation" match and the other is a "moderate confidence 5-8 generaton" match. I have to say I treat the commercial genealogical DNA ethnic origin tests with scepticism. I have read articles by scientists who consider them questionable and people who have taken the commercial tests with different companies report different results from each. Also, if you took the Ancestry DNA test more than a year ago and haven't checked for updates to the results I suggest you go in and do so. I took the Ancestry test last year and got the results on Christmas Eve. I was astonished to find that I was 34% Europe West, 33% Scandinavia, 13% Ireland and Scotland, 11% England, Wales and NW Europe, 8% Iberian Peninsula, 1% Europe South and 1% Europe East. There were also traces of Native American and Polynesian. A few months later I was telling this to a family member and went in to the DNA results to check the exact percentages when up popped a question "We have updated your DNA results, do you want to see the updated version? Obviously, I ticked yes, expecting a few percentage shift here and there but I now have the results 92% England, Wales and NW Europe (specifically Devon and Cornwall), 5% Ireland and Scotland and 3% France so make of that what you will. At least these results do correpond more closely with what I see in my family tree ( except for the French) but I still think the Ireland and Scotland percentages are wrong as that is half my mother's ancestry but maybe the DNA I inherited from her came mostly from the half she inherited from her English father and if my siblings took the test they might have a higher Scottish percentage. I still check for updates regularly, can't wait to see what my DNA ethnic origin will be next!

    3. You forgot the identical twins who were told they were from completely different ethnic backgrounds based on a DNA tests done at the same time.

    3. The following is from Ancestry’s FAQ which explains why ethnicity estimates have changed. Best regards Mike Rendle How could my estimate change over time? Your ethnicity estimate is based on the data we have and the methods we use to compare your results to that data. Because we're always collecting more data and our methods are constantly improving, your estimate may change over time. What might change? Your percentages for a region could change. Some new regions could appear. Some old regions, especially low-percentage regions, could disappear. Or you might not see much change at all. You could see new regions. When AncestryDNA launched in 2012, we compared your DNA against 22 possible regions. We now have more than 380. You could see old regions turn into new ones. For example, instead of one Iberian Peninsula region, we now have separate regions for Spain, Portugal, and Basque. And our Asia East region has been replaced by China, Korea and Northern Asia, Japan, Southeast Asia—Dai (Tai), Southeast Asia—Vietnam, and Philippines. You could see new percentages—higher or lower. Not only have new data and new methods enabled AncestryDNA to identify new regions, they have also improved our ability to determine how likely it is you belong to a region. These improvements mean that your percentages for a region could go up or down. You could see regions drop off your estimate. Because what AncestryDNA knows about the relationships between regions and DNA has improved, some regions may disappear from your estimate. This may be particularly true of regions that included 0% in the possible range on your earlier estimate.
