He clustered somewhere near the Mongols and Hezhe. I think Koreans are a unique case where geographic distances don't correlate heavily. Same for Ryukyuans. Ryukyuans, who are geographically closer to Taiwan and China are closer to Japanese and Koreans, genetically. A Korean friend of mine took an ancestry test similar to 23andme in Korea.

I have a few minor suggestions to make it more useful for 23andMe's customers: - allow one to zoom in even more than is now possible. If one has several genome-sharing-friends from a similar ethnic background, one should be able to zoom in to a level so that one can clearly distinguish them. - Next to each user's advanced-global-similarity window, have 4 boxes into which a user can type text describing the ethnic/geographic group (or "unknown") of each one of his/her 4 grandparents (paternal grandfather, paternal grandmother, maternal grandfather, maternal grandmother). - Allow one to right-click on each user's square, upon which the info about his/her 4 grandparents is displayed. - Similarly, allow one to right-click on the literature samples to display info about each one (which study, etc.). - Please include more reference populations, such as Ashkenazi & Sephardi Jews, people from distinct geographic regions within a country: Franconia (in Bavaria, Germany), Sorb ethnic group in Germany, etc. Overall, I am very positively impressed by your pace of innovation. :) Thank you 23andMe for offering this new tool.

When a family is looked at together, shouldn't the children tend to be merging around a central cluster, with the grandparents potentially the furthest out?

But the UI can be a little more simpler.. Maybe a phylogenetic tree like interface would be easier to understand :) This is good information. But the UI can be a little more simpler..
