This is a few years old, but this article was amazing to me! Topical with all the DNA testing gifts that will likely be given for Christmas. I have a few friends who have super interesting stories to tell re: their DNA testing adventures.

I also found a textbook photo they mention in the article, but do not show. I won't spoil it. But, it is available if you look on Amazon with their "Look Inside" feature. Fascinating and really makes you wonder......
