I didn't express surprise. I knew it.   What you don't know is that so far I have looked only at haplogroups, because I needed it for the purpose of my book. I haven't read virtually anything substantial about human or animal diversity until ca. 3 months ago and I was actually forced to study it, because I couldn't stand the crappy style of the Wikipedia article about race. Since I still have a lot of work with final editing the book, I don't have much time to occupy myself with it. Although I have collected about 100 articles about this topic during the last weeks, I have read only about half of them, mostly briefly. Hopefully next week, when everything will be eventually finished, I will start to read them in detail, one after another. So don't worry that I wouldn't catch up with you.
