Important! If you score 90 for Ötzi and 30 for Beethoven, this does not mean that you are genetically closer to Ötzi than to Beethoven. It only means that you are closer to Ötzi than most modern Europeans are, whereas most modern Europeans are closer to Beethoven than you are.
Because Beethoven lived only around 200 years ago, you are genetically much more similar to him than to Ötzi, who lived more than 5,000 years ago. Keep that in mind when looking at the scores!
Also: When it says "closer than all Europeans", what is meant is of course the underlying reference values of modern Europeans. However, the values were weighted by the population size of the respective country, so the results can be indeed transferred to today's Europe and one can speak genetically with some reliability of "all Europeans". However, the countries for which there is no data yet are left out.
