Ancestry.com just announced that with all the data they have now, they've been able to really refine their results. That means they can narrow down your DNA even better than before and they'll be sending you those results soon.
But it also means the results you originally got might change. Like, you might've thought you were part Viking because they estimated you were 9% Scandinavian. Well now, maybe they figured out that DNA was actually from England.
A spokesperson from Ancestry says they warn people that their results are an ESTIMATE and can change as more data comes in.
But people still aren't very happy with it. One woman told reporters that the update dropped her son from 31% Spanish to just 11% and quote, "It's quite upsetting."
"His ethnicity is massively different now. I haven't accepted it as I don't agree with the results."
