I mentioned last week that this news about being related to Genghis Khan is less interesting than it appears, now the NYTimes reports that the accountant in Florida is not a direct descendent after all. A second, more detailed test, by rival firm Family Tree DNA of Houston, showed that the first test was a fluke.
I've been skeptical of these tests because I'm not sure what kinds of quality controls exist for these companies, and I suspect that you might get different results depending on who does the test and when.
