I am of Mongolian descent?
July 16th, 2007 was a special day for two reasons: it officially marked the end of my 3-year Spanish learning and on the same day when I went to see a dentist for dental scaling, he told me that I may be of Mongolian descent since I have oral tori, a genetic legacy from Mongols according to the dentist.
This probably explains why I find Japanese familiar to me (even though whether Japanese belongs to Altaic family is still disputed).
I'm beginning to find intriguing the interplay between genetics, anthropology and historical linguistics...
